[Pkg-gmagick-im-team] Bug#849507: imagemagick-6.q16: convert generates monochrome images with inverted colors (black and white)

[Rogério Brito]

Package: imagemagick-6.q16
Version: 8:6.9.6.6+dfsg-1
Severity: normal

Hi.

I have a grayscale gif that I want to print for my son to color. In the
process, I wanted to convert it to monochrome, but, surprisingly, I got an
inverted image.

The command that I used was:

    convert MINIONS-PINTAR.gif -monochrome minions-pintar-mono.png

I am attaching the problematic file to this message.

If needed, please let me know and I will try my best to supply any extra
information.


Thanks,

Rogério Brito.
