Version 1.28 7/31/2017Software Upgrades
Add support for PhotoMetricInterpolation (reverse rendering).
Version 1.27 8/17/2016Bug Fix - Navigation Dialog
A bug in the navigation dialog resulted in a crash when loading an XOR coordinate list file. Fixed.Bug Fix - Loading Large Files
A bug that occurred when loading files > 2GB was fixed. Now using 64 bit version of fseek..Bug Fix - Greyscale parser
A bug in the greyscale bitmap parser was fixed.Enhancement - Open Dialog
The file open dialog now remembers the previously used directory.Bug Fix - Internet Explorer Interface
Help is provided HTML format - when the user's default HTML viewer was Internet Explorer the file name was not correctly passed. Fixed.BMP Output Orientation Fixed
BMP extraction changed to properly represent Y orientation. (Previously our BMP row order was reversed when compared to programs such as Adobe Photoshop.)
Version 1.26 7/26/2016Bug Fix
Tiff parser bug fixed (parsing SHORT sized header information).BMP Output Orientation Fixed
BMP extraction changed to properly represent Y orientation. (Previously our BMP row order was reversed when compared to programs such as Adobe Photoshop.
Version 1.24 12/22/2015Software Updates
New input format added "JDKPB_FMT" (specially formatted RAW).
Version 1.23 9/2/2015Software Updates
For BMP input files, recalculate the word-aligned width value for "XOR" process.
Version 1.22 8/5/2015Crash during XOR
There was a program crash during an XOR compare of two large files. This has been fixed.
Version 1.21 7/21/2015XOR Progress Bar added
A progress bar now appears during XOR comparisons giving the user progress details.Improved XOR Comparison Speed
XOR polygons are no longer drawn on the screen. The program only displays markers where the differences appear.
When XOR is running or when the XOR Navigation dialog is open, File | Open, Offset, Mirror functions are not allowed.
Filter value from the navigation dialog may not be smaller than the prefilter value.
Stores and applies layer color and transparency settings when more than one file is open.Bug Fix - Memory Leak
A memory leak that occurred while reading TIFF files has been eliminated.
Version 1.20 5/11/2015G2BMP Support for DCA
Added support for special BMP format - requested by DCA Inc (BMP files over 4GB).
Version 1.18 12/24/2014XOR Compare tool
XOR Tool added with multithreaded raster compare library. It requires acsbool64.dll acsRstrCmpLib64.dll.
Fixed crash when attempted to open more than 3 files.
Version 1.18 12/24/2014Breaks 4GB BMP Bitmap File Size Limit
Added support for opening and displaying BMP files greater than 4GB. Ignores the header of the BMP file where the file size is reported.Large File Optimization
Added new background compression/loading in order to handle extremely large (40GB) bitmaps even on machines with limited RAM.Hasp Key
Added support for HASP key.Bug Fix - Raw Alignment
Fixed a bug related to alignment for RAW bitmaps.Enhancement - Interrupt
User can now interrupt the program while it is loading/compressing the input file.Bug Fix - Progress Reporting
When importing BMP (4/8) files the progress is now reported correctly.
Version 1.17 05/11/2014Software crash
Software crash problem was fixed.
Version 1.16 05/9/2014Updates
Adopted new licensing scheme.
Version 1.15 03/14/2014Updates
Multithreaded compression at loading stage.
Version 1.13 12/11/2013Upgrades

Does not draw padding byte information for bmp input files.
Version 1.12 11/4/2013Upgrades
Greyscale TIFF support added.
Add a file from the layer dialog, change view/mirror settings, and doesn't apply the changed settings for the file added.
Version 1.11 09/16/2013Raw File
Remembers row size for RAW format.New Raster Format LGDMD
A new format for bitmaps has been added which we call LG DMD. This is a bitmap produced by sampling a normal bitmap using a DMD frame (either 1024x768 or 1920 x 1080) at a slight angle to the direction of DMD motion.Bug Fix
Report of pixel coordinates is more accurate now.Bug Fix
Missing the first pixel in each row fixed.
Version 1.10 09/04/2013
Fixes and Enhancements to User Interface
Automatically redraws the new home view after a transparency update
Layer dialog settings are disabled when the OK button is pressed
Layer dialog Apply button press draws the home view but user could not zoom from that point.
Version 1.09 08/23/2013
Improved Error Checking and Bug Fixes
Will no longer attempt to open a TIFF file that is greater than 4GB.
Verifies that an extracted TIFF image does not exceed 4GB.
A crash generated by the layer dialog has been fixed and the state of the "delete" button in the layer dialog has been fixed.
Tiff Extraction with Packbits
The ability to extract a window to TIFF w. packbits compression has been added. This is multi-threaded to take advantage of modern multi-core processors.
Version 1.08 07/11/2013
gross/fine offset adjustment (mouse, arrow keys).
add cursor to display when zoomtoxy (add a checkbox for "show cursor" to the toolbar) is invoked
return focus to the display after toolbar use.
layers settings dialog OK button resets the settings only when any of the settings is actually changed.
Zoom to XY tool shows current unit selected.
toolbar size issue fixed.
layer settings dialog "+" buttons added for each layer. (multiple selection allowed)
added tiff output option to window extractor.
Version 1.07 06/25/2013
Yes, same version twice ...BMP File Info
Fixed a bug when displaying BMP file info that showed incorrect file size.Mirror-in-Y

Inverse display now works as expected. (black foreground/white background -> white foreground/black background)
Version 1.07 06/18/2013Multi-Layer Support
Two files can be loaded and overlayed with color/transparency for comparison purposes.Physical Units
Coordinate display can now be shown in physical units in order to make measurements.
Version 1.06 06/05/2013New: Extract a Window ...
A window of data can now be extracted from the large bitmap. Output can be in TIF, BMP or RAW formats.BMP Header Item Added
