Problems with convert after update from 6.7.5.3 to 6.8.9.9

[kommzept]

Hello,
in out php application we are using functions of imagemagick. Since the last update (from 6.7.5.3 to 6.8.9.9) we got the problem, that creating images doesn't work the way it worked before.

The following command is in use:
convert -compose atop /kunden/410326_52064/webseiten/pdcms/cake/app/webroot/files/mosaics/00002/themes/00053/canvas_faded.png -colorspace RGB -strip /kunden/410326_52064/webseiten/pdcms/cake/app/webroot/files/mosaics/00002/themes/00053/user_images/s/faded/00006089.png -geometry +240+100 -composite /kunden/410326_52064/webseiten/pdcms/cake/app/webroot/files/mosaics/00002/themes/00053/canvas_faded.png

After running it two times with different files and using both times the file canvas_faded_png as source and target the result looks like this:
https://missio.schutzengel-fotoaktion.d ... ded_02.png

After running it five times
https://missio.schutzengel-fotoaktion.d ... ded_05.png

After running it ten times
https://missio.schutzengel-fotoaktion.d ... ded_10.png

Do you have any idea what I can do?

Thanks for your help.

-colorspace RGB is now -colorspace sRGB. There was a change of notation between those releases to conform to proper standards. See viewtopic.php?f=4&t=21269
