Follow-up Comment #1, bug #45565 (project octave):

When trying to write an 8-bit image to a BMP file,  the image ends up as a
24-bit image. This is not a problem with jpg and tif file format.

a = repmat (uint8 (0:255), 100, 1); 
imwrite (a, "test.jpg"); 
imwrite (a, "test.tif"); 
imwrite (a, "test.bmp");
