Package: file Version: 4.23-2 Severity: minor
Consider this blank .BMP:
# compress to show it's blank
% bzip2 < SM2000.bmp | wc -c
91
Convert to .PNG:
% convert SM2000.bmp SM2000.png
% file SM2000.*
SM2000.bmp: PC bitmap data, Windows 3.x format, 640 x 480 x 24
SM2000.png: PNG image data, 640 x 480, 8-bit/color RGB, non-interlaced
The BMP says 24 bits, and the PNG says '8-bit/color RGB' -- which
means 8 bits per color times 3 = 24? but it's still confusing having
two different numbering systems. 'x 24' is what was expected.
Attached is the BMP file, if anybody needs it.
Hope this helps...
