[Octave-bug-tracker] [bug #45565] Using imwrite to write an 8-bit iamge to BMP creates a 24 bit image

[Carnë Draug]

Follow-up Comment #5, bug #45565 (project octave):

Actually, if you enable ImageJ's SCIFIO2, or use the bioformats importer, then
ImageJ will open the file.

However, you can use the following which works fine in ImageJ, even when using
plain ImageJ 1.


octave> a = repmat (uint8 (0:255), 100, 1);
octave> img = uint8 (ones (100, 1) .* [0:255]);
octave> map = rainbow (256);
octave> imwrite (ind2rgb (img, map), "foo.bmp");
