PANCROMA

Upgrades

February 17, 2012. Version 5.43. Added color zoom in utility.
February 12, 2012. Version 5.42. Added simple North-is-up image georeferencing.
February 11, 2012. Version 5.41 Many PANCROMA utilities would not work with 16-bit input files, including some basic ones that I apparently disabled by adding sentinels. Most of these are not enabled for EO-1 ALI and similar 16-bit data.
February 10, 2012. Version 5.40 Released SPOT Point Spectrum Generator and EO-1 ALI Point Spectrum Generator. Fixed several bugs and made improvements to ASTER and SPOT Spectral Analyzers.
February 7, 2012. Version 5.39 Fixed a bug in the ASTER Spectral Analyzer. Added ASTER Point Spectrum Generator.
February 6, 2012. Version 5.38 Fixed a bug in the Landsat Point Spectrum Generator that was resetting the data input files when the 'retain settings' check box was checked.
February 5, 2012. Version 5.37 Added Landsat Reflectance Point Spectrum Generator.
February 4, 2012. Version 5.36 Added Landsat DN Point Spectrum Generator.
January 29, 2012. Version 5.35 Fixed a broken sentinal on the HSI processor that was preventing even multiple input files from getting by.
January 28, 2012. Version 5.34 Added image zoom capability for grayscale images.
January 27, 2012. Version 5.33 Added Landsat Surface Reflectance capability to Landsat Spectral Analyzer.
January 24, 2012. Version 5.32 Added EO-1 ALI Spectral Analyzer. Added 14.25m to 15.0m scaling utility.
January 18, 2012. Version 5.30 Added capability to read GLOVIS Landsat Reflectance files, including the 6-file Planar Configuration=2 multispectral bundle.
January 17, 2012. Version 5.29 Fixed a bug that prevented Digital Globe WorldView2 files from saving reliably after unbundling. Restored Big Endian 16-bit GeoTiff file save capability.
January 16, 2012. Version 5.28 Somewhere along the line PANCROMA lost its ability to save converted 16 bit and 11 bit band files with the GeoTiff bitsPerSample tag set to the correct '8' value. This prevented the files from being properly read. The problem is now corrected.
January 15, 2012. Version 5.26, 5.27 Added ASTER TOA Reflectance and Radiance utilities. Added ASTER Spectral Analyzer.
January 15, 2012. Version 5.25. Fixed a bug that prevented PANCROMA from reading 16-bit EO-1 ALI and Landsat surface reflectance files.
January 14, 2012. Version 5.23, 5.24. Fixed a bug in the TERAS gap filling utility that prevented the Cloud Saturation Cutoff value from exceeding '8', which prevented it from being useful. Modified all gap filling utilities so that they can gap fill from another gap image, rather than a pre-2003 SLC-On image.
January 14, 2012. Version 5.22. Minor house keeping changes and checks on the two Cloud Mask utilities.
January 13, 2012. Version 5.21. Added SPOT TOA Reflectance and Radiance utilities. Improved the Landsat Surface Temperature utility so that it uses the proper Gain and Bias calibration coefficients depending on whether an ETM+ or TM file is input, and whether the ETM+ is the high gain (...61) or low gain (...62) band file. The gain level is read automacally.
January 13, 2012. Version 5.20. Corrected a bug in the PANCROMA TOA Reflectance algorithms that prevented the solar elevation angle from being read correctly from the data input screen. The bug caused the solar elevation angle to be a constant 38 degrees instead of the user-input value. Unfortunately, this bug affected all algorithms that use TOA reflectance, including Tasseled Cap, Spectral Analyzer and Surface Temperatures. The error is now corrected. Sorry for the mistake.
January 8, 2012. Version 5.19. Added Landsat Spectral Analyzer.
January 7, 2012. Version 5.18. I accidentally broke the gap fill Transfer Method by un-commenting a delete command, causing an access violation. Sorry for any problems this caused.
January 5, 2012. Version 5.17. Made several improvements to the Landsat Registration utility, including toggle sequencing of input files and the addition of latitude and longitude coordinate reporting for both the base and adjust images. Modified the Six File Subset utility to handle Landsat 5 data which is often Planar Configuration=2. Updated the Instruction Manual.
December 30, 2011. Version 5.16. Added ELIN Local Optimization algorithm to HIS Transformation. Small upgrade to TERAS gap fill algorithm. Added NBR vegetation index.
December 29, 2011. Version 5.15. Added Six File Batch Processing for TERAS Gap Filling algorithm. Reorganized gap fill menu selections to allow trial use of Hayes and TERAS methods.
December 29, 2011. Version 5.14. Fixed the Six File Hayes Gap Fill Method. The GeoTiff save utility was not writing the GeoTiff 'bitsPerSample' tag correctly, and this resulted in an unreadable file.
December 23, 2011. Version 5.12. Added the TERAS gap filling algorithm. TERAS produces fast, high quality gap filled images.
December 18, 2011. Version 5.11. Corrected a problem processing L1G panchromatic file Scatter Plots.
December 18, 2011. Version 5.09. Corrected some bugs in the X-Y Scatter Plot and Single Linear Regression utilities.
December 17, 2011. Version 5.08. Made several improvements to X-Y Scatter Plot and Regression utilities. Added color coding to the plot points to indicate how many replicates there are per point. Eliminated no-data (zero) pixels from the scatter plot display and the regression compututations for single and double independent band regression analysis. This prevents the intercepts from being skewed by the preponderance of black collar pixels in full-size landsat images. Fixed an input band swap for sinlge band regression of TIF format files.
December 11, 2011. Version 5.07. Added TOA Reflectance as an option for Tasseled Cap transformation computation.
December 10, 2011. Version 5.06. Fixed the sentinal guarding the coordinate entry for the subsetting utility so that it now catches an empty textbox without creating an illegal floating point error.
December 9, 2011. Version 5.05. Improved the band ratio utility.
December 7, 2011. Version 5.04. Added Tasseled Cap transformation utility.
December 5, 2011. Version 5.03. Fixed an incorrect system information message for TOA radiance computation. Corrected the data entry box so that unnecessary information sliders are not visible.
December 2, 2011. Version 5.02. Added four independent band file multiple linear regression and four file linear transform capability.
November 28, 2011. Version 5.01. Corrected a diagnostic error that I accidentally left in the code that prevented the GeoTiff writer from writing the UTM corner coordinates. Sorry for any problems this may have caused.
November 27, 2011. Version 5.00. Added system setting status indication. Made a few modifications to the default settings for the regression and linear transformation utilities.
November 26, 2011. Version 4.99. This version posted as BETA. Added linear regression for three independent band files, i.e. solve the equation Y =b0 + b1X1 + b2X2 + b3X3 for b0, b1, b2 and b3 given independent band files X1, X2 and X3 and dependent band file Y. Also added a three-file linear transformation utility, i.e. when given the coefficients b0, b1, b2 and b3, solve the equation Y =b0 + b1X1 + b2X2 + b3X3 for Y where Y is a linear combination of the band files Xi. Also added a switch to disable the file size verification sentinal as this can sometimes prevent the processing of legitimate input files.
November 18, 2011. Version 4.96. This version posted as BETA. Modified the IEEE FP32 utility so that it can flip and unflip the image as many times as you want. Also added information messages to more menu selections.
November 12, 2011. Version 4.95. This version posted as BETA. Contains utility to read IEEE FP32 WorldWind elevation DEMs and flip them (but not the coordinate system) to correct downloads from the WorldWind SDK.
November 8, 2011. Version 4.94. Completed more improvements for flip and rotate images. This is for handling WorldView data. More to follow.
November 7, 2011. Version 4.93. Added image flip and rotate post process utility.
November 5, 2011. Version 4.92. Added one and two band linear combination computation.
November 4, 2011. Version 4.91. Added two band multiple regression capability.
October 29, 2011. Version 4.90. Added X-Y band linear regression capability.
October 28, 2011. Version 4.89. Added X-Y band scatter plot utility.
October 20, 2011. Version 4.88. Added Landsat Surface Temperature computation utility for converting TIR band 6 DNs to degrees Kelvin.
October 16, 2011. Version 4.87. Added Landsat GEOCOVER Spectral Transformer utility. This feature transforms false color GEOCOVER bands 7, 4, 2 images to natural color RGB images, allowing greater utility of this high quality NASA data set.
October 15, 2011. Version 4.86. Fixed a bug that prevented band file images from being saved when generaged from JPEG RGB inages.
October 8, 2011. Version 4.85. Upgraded the HSI algorithm to create more natural looking vegetation tones when pan sharpening Landsat data. Upgraded the AJISANE algorithm and added 'Landsat Color Enhancement' option to improve color tones. Fixed some bugs that prevented contrast adjustment and sharpening input from being executed during batch processing.
October 7, 2011. Version 4.84. Added a 'Landsat Color Enhancement' option for HSI processing. Activate by checking the box on the Pan Sharpend Data Form.
September 30, 2011. Version 4.83. Fixed Brovey algorithm so that the image processing utilities have some effect on the outcome, which they did not previously.
September 30, 2011. Version 4.82. Enabled 'Display One Grayscale Band Image' and SPECTRAL pan sharpening utility to handle Landsat Band 6 60m resolution images.
September 28, 2011. Version 4.81. Enabled three file cloud mask to handle both 30m and 60m TIR band files.
September 25, 2011. Version 4.80. Fixed a hopefully obscure bug in the routine that computes the Saturation array for HSI processing. Hopefully it was too obscure to cause problems but I caught it processing a color test pattern image. Added SPOT single band pan sharpening.
September 24, 2011. Version 4.79. Added SPECTRAL pan sharpening algorithm for pan sharpening single multispectral and hyperspectral bands. Fixed some issues with saving grayscal JPEG and PNG images.
September 18, 2011. Version 4.78. Added MSAVI2 vegitation index and the ability to write the raw index data to a binary file.
September 14, 2011. Version 4.77. Fixed an off-by-one (pixel) error in the image subsetting utility.
September 12, 2011. Version 4.76 Added file type information boxes so you can tell what file types PANCROMA is expecting and a 'System' menu selection so you can turn off the bloody things if you don't want them.
September 10, 2011. Version 4.74, 4.75 Made several small improvements to the XIONG and AJISANE pan sharpening algorithms, including adding Laplacian interpolation to XIONG and adding 'Change Dark Pixels' to AJISANE.
September 9, 2011. Version 4.73. Made some final adjustments to the scale factors for vegetation indices. Changed the default XIONG factor from zero to 0.3.
September 5, 2011. Version 4.72. Improved image quality for ENHG pan sharpening utility. Modified rendering of VI indices.
September 5, 2011. Version 4.70. Added four Vegitation Indices and uploaded Revision 23 of the PANCROMA Instruction Manual that explains their use.

August 14, 2011. Uploaded Revision 20 of the PANCROMA Instruction Manual. Section 55 contains a workflow tutorial for gap filling and pan sharpening Landsat data sets.
August 13, 2011. Version 4.65. Fixed a serious bug in the Transfer Gap Fill utility. I set the default search threshold too high i.e. grayscale=30. This is the value below which a substitution will be made from the ungapped file. I reset it to 4.
August 13, 2011. Version 4.64. Modified HSI XIONG algorithm to produce higher quality images by removing artifacts and using the image average as the 'floor' value for the image subtraction test. Also automatically compute 'alpha' the NIR band multiplier based on maximum value that does not cause processed values less than zero.
August 13, 2011. Version 4.63. Modified HSI algorithm to remove unwanted edge artifacts when processing gap images.
August 6, 2011. Version 4.62. Added batch processing for Hayes algorithm. Since processing three pairs of files by the Hayes gap fill method can be time consuming, I added a batch utility so that your entire RGB band set can run in the background.
August 5, 2011. Version 4.61. Fixed a bug in the 'Subset One Band' utility that prevented subsetting a file if you keyed in the coordinates rather than picking them with the mouse. Fixed a second bug in the 'Subset Four Bands' utility that wrote the wrong xScale and yScale factors to the band1 subset GeoTiff format image. (This also resulted in the latitudes and longitudes being incorrectly computed for this band.)
August 2, 2011. Version 4.60. Fixed the Batch RGB processor, which I accidentally broke in the process of adding another module. Modified the GeoTiff file reader to handle Landsat 4/5 Planar Configuration=2 format.
July 31, 2011. Version 4.59. Added image registration of two images by linear transformation. Fixed an image caption re-initialization error.
July 24, 2011. Version 4.58. Fixed a bug that recorded and saved the wrong rasterX and rasterY tie points for GeoTiff band files where these are non-zero.
July 15, 2011. Version 4.57. Found and corrected a couple of bugs in 'Subset Six Bands' utility.
July 15, 2011. Version 4.56. Made an improvement to the 'Subset Six Bands' utility to improve the quality of the registration.
July 14, 2011. Version 4.55. Corrected several bugs that were preventing the 'Subset by Coordinates' using the 'Maximum Common Extents' option from working.
July 10, 2011. Version 4.54. Added automatic image registrtion for two sets of three band files. This utility is useful for gap filling and cloud masking. It replaces the series of manual utiities formerly required. Documentation is currently sparse. See p 24 of the User Guide. More documentation and a Tutorial will follow.
July 8, 2011. Version 4.53. Fixed a bug that reversed the X and Y scale factors when resizing images. This was only a problem when the Xscale did not equal the Yscale.
July 7, 2011. Version 4.52. Fixed a bug in 'Subset Four Bands' utility that inserted the wrong scale factor into the panchromatic tiff file. The scale factor was off by 2X, i.e. 30m instead of 15m for a typical Landsat panchromatic band.
July 1, 2011. Version 4.51. Improved the information reported to the Subset Coordinate Report form. Made a memory allocation adjustment that should allow most users to subset full-sized four file data sets (three band files plus panchromatic band).
June 29, 2011. Version 4.50. Fixed a bug in the 'Compute Maximum Extents' utility.
June 26, 2011. Version 4.49. PANCROMA can now handle GeoTiff Affine Coordinate Transformations (in order to read Landsat affine format and GLCF ASTER L1A, for example).
June 21, 2011. Version 4.48. Added more sentinals on index file writer for SRTM DTED writer. Added graphics file output capability.
June 13, 2011. Version 4.47. Added SRTM DTED2 file reading capability.
June 12, 2011. Version 4.46. Added 'Enhanced' adjusted intensity array computation to AJISANE pan sharpening algorithm.
June 12, 2011. Version 4.45. Added LSQR interpolation method in single-scene and stand alone implementations. Added sentinals in case L1G metafile file read error occurs.
May 22, 2011. Version 4.44. Added thumbnail image capability to 'Display RGB Image'.
May 21, 2011. Version 4.43. Fixed a minor bug in L1G Landsat format subsetting.
May 21, 2011. Version 4.42. Added AJISANE transform pan sharpen algorithm to the batch file processing menu selection.
May 18, 2011. Version 4.41. Fixed a menu sequencing bug in calibrate images utility.
May 15, 2011. Version 4.40. Added AJISANE transform pan sharpen algorithm.
May 14, 2011. Version 4.39. Fixed two bugs related to the addition of thumbnail image in version 4.27. The more serious one crashed the program when the 'Display Pan sharpend Image' check box was unchecked. The second caused a crash when an illegal TIFF file was encountered, instead of a graceful exit as intended.
May 6, 2011. Version 4.38. Added Haze Optimized Transform haze reduction utility.
May 1, 2011. Version 4.38. Added Dark Image haze reduction utility.
April 30, 2011. Version 4.37. Fixed an off-by-one error between screen pixels and latitude/longitude coordinates. This was causing a disagreement between reported screen coordinates and geographic coordinates equal to xScale or yScale meters. This also affected image subsetting but is also now corrected. Fixed the 28.5m-to-30m scaling utility whereby the dual multiplication between row/column scaling and xScale/yScale was causing a small error in the xScale and yScale values. These fixes allow band files subsetted using the 'Compute Maximum Common Extents' utility to match excatly so that a subsequent resizing is not necessary. Added buffer pixels to the Five File Cloud mask method to eliminate cloud fringes. Updated the User Manual to version 10 and added a new tutorial video.
April 25, 2011. Version 4.35. Fixed error in Resize Single File utility that caused wrong scale factor to be saved. Added utility to resize Landsat 28.5m resolution files to 30m resolution.
April 24, 2011. Version 4.34. Added Martinuzzi and Luo cloud mask utilities.
April 20, 2011. Version 4.33. Fixed a bug reading the last strip of an RGB image.

April 15, 2011. Version 4.29. Fixed a problem with menu sequencing for anaglyph processing.
April 10, 2011. Version 4.28. Added compute single and double histogram menu selection. Added red/blue color and grayscale anaglyph capability.
April 7, 2011. Version 4.27. Added a thumbnail rendering that displays along with the main image.
April 2, 2011. Version 4.26. Upgraded the menu sequencing.
March 27, 2011. Version 4.25. Fixed memory allocation error in the Resize Four Images utility that caused an intermittent access violation. Enabled subset data retention in the Subset Five Bands utility. Added fringe fill to Hayes Gap Fill algorithm.
March 25, 2011. Version 4.24. Fixed a problem with a frozen Comparison Radius for the Hayes algorithm.
March 20, 2011. Version 4.23. Improved Hayes Interpolation algorithm.
March 20, 2011. Version 4.22. Fixed a bug that caused an access violation processing non-GeoTiff TIFF files. Added Hayes Interpolation algorithm for gap fillng Landsat images.

March 13, 2011. Version 4.20. Added capability to read GeoEye bundled multispectral files in GeoTiff uncompressed tiled format.
March 12, 2011. Version 4.19. Fixed GeoTiff file save when pan sharpening 'Display Image' was unchecked. Added capability to read grayscale GeoTiff tile format.
February 21, 2011. Version 4.18. Enabled screen reporting for unprojected latitude and longitude coordinate system.
February 14, 2011. Version 4.16. Modified 'Display One File' and 'Subset One Band' utilities to allow processing of much larger band images. Improved menu enabling to make sequencing more intuitive. Added 'out of memory' error trapping.
February 14, 2011. Version 4.14. Fixed PNG reader. Fixed GeoTiff writer to handle PNG, JPEG and BMP grayscale input files. Fixed subset one file utility.
February 11, 2011. Version 4.13. Added single file subset mode. Added scale factor to image ratio.
February 11, 2011. Version 4.12. Fixed some problems with menu enabling that inadvertently permitted unwanted program states.
February 11, 2011. Version 4.11. Added sentries to guard against specifying subset coordinates outside the bounds of the image. I also added one to prevent a hard crash when attempting to open a tiled GeoTiff.
February 5, 2011. Version 4.10 Added EO-1 Advanced Land Imager file processing capability.
January 22, 2011. Version 4.08 Added WorldView2 top-of-atmosphere spectral radiance calibration utility.
January 15, 2011. Version 4.07 Added Thin Plate interpolation, histogram stretch, and image indexing, all designed to facilitate WorldView2 image processing.
January 11, 2011. Version 4.06 Added percent area computation and cluster highlighting feature to unsupervised classification utility.
January 9, 2011. Version 4.06 Added a post processing unsupervised image classification utility using Michiel Jan Laurens de Hoon's C-Clustering algorithms. This is a beta feature and I have much work to do before this is really useful. However I decided to offer it as an indication of future capability.
January 8, 2011. Version 4.05 Added Band Ratio computation.
January 1, 2011. Fixed several things that were broken in the batch processing utilities. These should be operating correctly now.
December 31, 2010. Added Resize and Subset utilities for pan sharpening Landsat with SPOT data. Fixed several bugs including: reversed band order in ASTER decomposition; broken BMP and JPEG save menu selections; Display One File large L1G display.
December 28, 2010. Version 4.01 Upgraded the Subset and Batch Pan Sharpen utilities to handle Digital Globe 4X multispectral to panchromatic ratio input files (GeoTiff format only).
December 26, 2010. Version 4.00. PANCROMA now reads all Digital Globe formats listed on the sample data download pages for the two companies. PANCROMA can now pan sharpen multispectral band files from Digital Globe and handle other untiled GeoTiff input data where the panchromatic band is 4X the multispectral bands. See the Instruction Manual for details.
December 19, 2010. Version 3.18. Added the ability to read Digital Globe 8-bit four file data bundles. Added the ability to create an elevation versus coordinate listing for DTED1 DEM files. Fixed a glitch in the Instruction Manual where one of the images was obscuring the first Tutorial.
December 12, 2010. Version 3.17. Added the ability to read Digital Globe 8-bit and 11-bit grayscale and RGB GeoTiff images.
December 9, 2010. Version 3.16. Fixed a bug that entered the wrong scale factors for pan sharpened files saved in GeoTiff format.
December 6, 2010. Version 3.15. Fixed a bug in BMP save after subset.
December 5, 2010. Version 3.13. Added the ability to read and display 11-bit GEOEYE TIFF grayscale files.
December 3, 2010. Version 3.12. Upgraded the TIFF file sentinals to help prevent unsupported TIFF file format files from creating access violations. Upgraded the 'Display One File' utility to read larger grayscale and RGB files faster.
November 27, 2010. Version 3.11. Improved the 'Remove Highlights' correction utility.
November 24, 2010. Version 3.10. Fixed problems in ENHG JPEG processing and Brovey Transform JPEG processing that caused access faults.
November 23, 2010. Version 3.09. Fixed a problem that prevented grayscale Big Endian TIFF files from being read. Fixed several problems that kept the image processing input box from displaying properly.
November 22, 2010. Version 3.08. Fixed a problem that was preventing the XIONG processor from picking up the scale factor input from the graphics input screen.
November 21, 2010. Version 3.07. Discovered that some Landsat files do on include a 'Samples per Pixel' TIFF tag, one that I was using to discriminate between grayscale and color input files. This caused a file read fault for such files. Rewrote the applicable code so that this tag is no longer referenced. Sorry for any issues this may have caused. Also added XIONG algorithm to pan sharpen batch processing. Added histogram stretch and image subtraction preprocessing utilities.
November 16, 2010. Version 3.06. Program apparently needed a rebuild to deal with a failure in the TIFF file reader.
November 15, 2010. Version 3.05. Fixed a memory leak in XIONG processor.
November 14, 2010. Version 3.04. Added XIONG spectral distortion correction for pan sharpened files. Fixed a bug that caused a fault in ENHG processing if the image processing data input box was not enabled.
November 13, 2010. Version 3.03. Modified TIFF writer to write a more reasonable ten rows per strip. This will decrease RAM usage during file load.
November 11, 2010. Version 3.02. Fixed image subsetting save for 3 files. Added GeoTiff file save for image resizing.
November 10, 2010. Version 3.01. Added coordinate screen reporting and GeoTiff file save capability to image subsetting.
November 7, 2010. Version 3.00. Added pan sharpen batch processing.
October 31, 2010. Version 2.38. Added GeoTiff output capability to L1G files.
October 31, 2010. Version 2.37. Added georeferencing to L1G format files.
October 30, 2010. Version 2.36. Fixed RGB batch file processing that I accidentally broke when installing the GeoTiff writer.
October 30, 2010. Version 2.35. Modified the GeoTiff writer to increase the number of strips to four and modified the GeoTiff reader to read by strip instead of the whole file. The program does a better job of reading its own full sized Landsat pan sharpened output and other applications should have an easier time too.
October 27, 2010. Version 2.34. Fixed what I think is the last major issue for the GeoTiff file writer. I forgot to insert the four byte '0x00' terminator at the end of the IDF tag array, and this caused Windows Photo Gallery and GIMP to object. I now cannot find an application that will not read the output files so I think the writer is reasonably solid.
October 26, 2010. Version 2.33. Fixed an error in the GeoKey array that was preventing MicroDem from reading GeoTiff format.
October 25, 2010. Version 2.32. Fixed problem reading GeoTiff files into Global Mapper. PANCROMA output GeoTiff files read correctly in all cases.
October 24, 2010. Version 2.31. This is the beta release of the GeoTiff writer version. The GeoTiff Writer will now output grayscale and RGB type files. The current version of the TIF writer has been tested for compatibility with the same applications listed for v2.30. In addition the TIF files contain embedded GeoTiff Tags and GeoKeys. I checked the outputs for internal compatibility (PANCROMA out; PANCROMA in) with complete success in my test matrix. Also tested against Global Mapper and Arc Gis. Known issues:

Global Mapper reads the latitude and longitude correctly but only seems to pick up the projection for Big-Endian input files. If you input the projection information manually should work OK.
Arc View reads the latitude and longitude correctly only for Northern hemisphere files. Cannot find any projection information at all. You may be able to enter manually here as well.
Arc View does not read the latitude and longitude correctly for Southern hemisphere files. However my version showed the same errors for the source Landsat band file so I think this is related to the unconventional negative longitude corner coordinate data that is the Landsat convention.
PANCROMA may issue an allocation fault error when reading full sized Landsat pan sharpened TIF files. The program needs some internal tuning to solve this problem

Will continue to work on this capability. Check periodically for upgrades.

October 22, 2010. Version 2.30. Improved the PANCROMA TIF writer. Successfully opened PANCROMA TIF files using PaintShop, Photoshop, Illustrator, Paint, PowerPoint, Global Mapper and ArcGis. Notable failure to open using Microsoft Photo Gallery. Continuing to test and develop this feature.
October 17, 2010. Version 2.29. Added a TIF writer to PANCROMA. The utility writes TIF not GeoTiff at this time. GeoTiff capability should follow shortly.
October 11, 2010. Version 2.28. Fixed an uncaught error when a compressed TIF file format (other than Compression=1) is encountered.
October 10, 2010. Version 2.27. Added the ability to histogram match two files as a preprocessing utility. Updated Instruction Manual.

Apologies to any users that encountered this bug. Upgrades for this version include the ability to subset three band images by any of the three standard methods including latitude and longitude coordinate input. Also added the ability to resize images. These two additions along with the histogram matching added in the previous version should provide all the tools necessary to gap fill images without depending on any external applications.
September 25, 2010. Version 2.19. Added histogram matching to Gap Filling algoritms. Added Histogram Form for graphical display of image histograms.

August 7, 2010. Version 1.26. Added ASTER natural color capability, combining ASTER band files 1, 2 and 3N to create a natural-looking image. Added automatic tif file type detection for loading and displaying single tif files.
August 4, 2010. Version 1.25. Fixed a bug that prevented smaller files from being saved in JPEG format. Added file save overwrite warning (about time!)
August 3, 2010. Version 1.24. Upgraded JPEG file save utility. PANCROMA can now save full size JPEG images when 'Display Pan Sharpened Image' is unchecked.
July 31, 2010. Version 1.23. Fixed a memory leak in the large file BMP writer that may have interefered with some computers saving this file when the 'Display Pan Sharpened Image' check box was unchecked. Added PNG file support to this large file configuration. Added JPEG and BMP capability to 'Display One Color Composite Image' menu selection.
July 25, 2010. Version 1.22. Effected further increase in pan sharpening processing speeds. Fixed broken RGB Comparison Image form.
July 24, 2010. Version 1.21. Modified code to cut processing time for large pan sharpened images by 50%. Fixed several bugs: problem with scratch file that prevented some files from properly pan sharpening; fixed RGB jpeg file compression accidentally set to 1; fixed Brovey transform for large files; fixed broken subsetting routine; added .tif filters to prevent inappropriate tif file formats (palette images for example) from being read.
July 20, 2010. Version 1.20 fixed a bug that prevented 256MB RAM computers from reading and displaying a Landsat panchromatic image. Increased speed for pan sharpeneing large files.
July 15, 2010. Version 1.19 fixed a bug that prevented reading a single grayscale image and a single RGB image that I accidentally introduced while fixing another bug.
