Hi,

Once I upgraded ImageAPI module from 5.x.1.4 to 5.x.1.5 one of my imagecache profiles stopped working. The problematic action was Negative Image. The profile includes 'scale & crop 20x20' followed by 'Negative Image'. The input image is 16x16.

The resulting train of errors begins with:

imagesavealpha(): supplied argument is not a valid Image resource in xxx.com/development/web/sites/all/modules/imagecache_actions/imagecache_coloractions.module on line 200.

imagefilter() expects parameter 1 to be resource, null given in xxx.com/development/web/sites/all/modules/imagecache_actions/imagecache_coloractions.module on line 201.

I'm using imagecache 5.x.2.6 and imagecache_actions 5.x.2.3. Once I downgraded imageapi to 5.x.1.4 the profile started functioning again.

Best,
Ron
