BMP Suite Version 2.6 This is a set of Windows BMP image files, and a utility for generating them. Many different varieties of BMP files are included, and are intended to be useful for testing.

See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see <http://www.gnu.org/licenses/>. The ICC profiles in the "data" subdirectory are not covered by this license. The swap-r-g.icc profile is the same one used in the MNG test-suite. Image files generated by this program are not covered by this license, and are in the public domain (except for the embedded ICC profiles). Files in the "g" directory I consider to be "good": Your program should definitely support them if it claims to support BMP. Files in the "q" directory I consider to be "questionable": These may unusual or obsolete, or technically violate the documentation in some way, or I may be unsure about their validity. Files in the "b" directory I consider to be "bad": These are clearly invalid or unreasonable. Make sure your program doesn't crash when reading them. The "x" directory contains files in formats related to BMP, that you might not consider to truly be in "BMP format". The individual BMP files are described in the html/bmpsuite.html file. The generation utility is written in C, and is contained in the bmpsuite.c file, and the files in the 'data' subdirectory. In a Unix-like environment, type "make bmpsuite" to build the program, or just "make" to build and run it. Run "make check" to verify that it writes the BMP files correctly. The data/pal1huff.tif and data/pal1huff.g3 files were created essentially as follows: (Using Unix tools. 'convert' is from ImageMagick; 'tiffcp' and 'tiffinfo' are from libtiff.) $ convert g/pal1wb.bmp -flip -compress Fax -orient bottom-left -define tiff:photometric=min-is-white temp.tif $ tiffcp -c g3:1d temp.tif data/pal1huff.tif $ tiffinfo -s data/pal1huff.tif ... 1 Strips: 0: [ 8, 2065] $ tail -c +9 data/pal1huff.tif | head -c 2065 > data/pal1huff.g3
