[Pkg-gmagick-im-team] Bug#848849: convert fails to interpret STDIN data

[Eduard Bloch]

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

Should be self-explaining:

$ xwd -root | file -
/dev/stdin: XWD X Window Dump image data, "xwdump", 1280x1024x24
$ xwd -root | convert - /tmp/foo.png
convert-im6.q16: no decode delegate for this image format `' @ error/constitute.c/ReadImage/504.
convert-im6.q16: no images defined `/tmp/foo.png' @ error/convert.c/ConvertImageCommand/3257.
$ xwd -root > /tmp/foo.xwd ; convert /tmp/foo.xwd /tmp/foo.png
$ echo $?
0
$ file /tmp/foo.png 
/tmp/foo.png: PNG image data, 1280 x 1024, 8-bit/color RGB, non-interlaced
