[Octave-bug-tracker] [bug #47746] imwrite writes incorrect TIFF pixel values from uint8 array on i686-linux-gnu

[Mike Miller]

Follow-up Comment #9, bug #47746 (project octave):

I inserted my test program directly into __magick_read__.cc, right before
__magick_write__ returns, and it produces the correct output file.

So I am now calling Octave with this one-liner:


imwrite (repmat (uint8 (0:255), 1, 1, 3), 'testoct.tif', 'Alpha',
uint8(0:255))


Meanwhile the body of my test program is running inside of __magick_write__
producing a separate tif file, with what I believe are the exact same pixel
values being written, and the files still differ.
