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

[Mike Miller]

Update of bug #45565 (project octave):

              Item Group:        Incorrect Result => Matlab Compatibility   
                  Status:            Works For Me => Confirmed              
                 Summary: Using imwrite to write an 8-bit iamge to BMP creates
a 24 bit image => Using imwrite to write an 8-bit image to BMP creates a
24-bit image

    _______________________________________________________

Follow-up Comment #17:

Confirmed with Matlab that imwrite creates an uncompressed 8-bit-per-pixel BMP
file when the array is of type uint8, no need to specify a colormap. Also
confirmed that Matlab creates an uncompressed 1-bit-per-pixel BMP image when
the array is logical. In both cases the file is an indexed image file with
implicit grayscale colormaps.

Updating to confirmed and Matlab compatibility.
