Description

After upgrading imagemagick to new version are all new generated images darker as uploaded. Problem is caused by changing colorspace in imagemagick (probably from version 6.7.0). There is simple fix: just change (3 times) -colorspace RGB to -colorspace sRGB in class.t3lib_stdgraphic.php. But nicer will be to have version depending switch or possibility change colorspace in install tool.

our conf:
php 5.3.5
imagemagick 6.7.5-5
typo3 4.5.14 and 4.5.15

It seems, that same problem will be on 4.6 and 4.7 too, because they use also -colorspace RGB.

Bug still exists on this configuration:
php 5.3.13
imagemagick 6.7.8-6
typo3 4.7.4

Replacing RGB to sRGB (3 times) helps, many thanks to Jan Perdoch

I had to upgrade ImageMagick because the old versions had security issues. Can confirm this bug with:

Typo3/4.7.4
ImageMagick-nox11-6.7.9.4

Came across this problem as well. Config:

php 5.4.7
ImageMagick 6.8.0.4
Typo3 4.5.20

I changed the IM parameters in the source as described above, seemed more straight forward to me in this case, than trying to create wrappers etc. ;). Hopefully this gets fixed in Typo3's source too at some point

I tried to solve the problem by identifing the ImageMagick version with the identify command, which worked well for me. Maybe there is a better solution. But for now here is my one. The diff was created with a 4.7.4 core.

Maybe all these Typo3 ImageMagick settings (negate mask, mask inv. etc) could be replaced by an "ImageMagick version" setting that contains the full version info (not just major number)? All further settings could be derived from this one.

I would definitly prefer a version based preset, that all manual settings :D -> the manual should be still applyable in the Localconfiguration :D
