[Pkg-gmagick-im-team] Bug#901680: imagemagick-6.q16: convert / drawing primitives: colourspace handling broken

[Juha Jäykkä]

Package: imagemagick-6.q16
Version: 8:6.9.9.39+dfsg-1
Severity: normal

Dear Maintainer,

I would expect

convert foo.pdf'[0]' -draw "fill #ffffffff rectangle 40,225 560,280" broken.jpg
convert foo.pdf'[0]' temp.jpeg; convert temp.jpeg -draw "fill #ffffffff rectangle 40,225 560,280" broken.jpg
convert foo.pdf'[0]' temp.png; convert temp.png -draw "fill #ffffffff rectangle 40,225 560,280" broken.jpg

all to produce the same resulting image. They do not. The first two draw a *black*, opaque rectangle, which 
by the way is semi-transparent when viewed in windows 10 "photos" application, and the third line creates a 
*white*, opaque rectangle. Obviously, all should create a white rectangle.

Cheers,
Juha
