Update of bug #45565 (project octave):
Release: 4.0.0 => dev
_______________________________________________________
Follow-up Comment #3:
This bug (or lack of it), may be dependent on the version of Graphics Magick
installed.
I can see a bug with it but different from the one originally reported:
octave> a = repmat (uint8 (0:255), 100, 1);
octave> imwrite (a, "test.bmp");
octave> [b, c, d] = imread ("test.bmp");
octave> whos
Variables in the current scope:
Attr Name Size Bytes Class
==== ==== ==== ===== =====
a 100x256 25600 uint8
b 100x256 25600 uint8
c 0x0 0 double
d 0x0 0 double
If a bmp file is always an indexed image (is this true?), then it should have
returned a colormap.
