[TYPO3-english] Imagemagick images too dark?

Wed Apr 18 09:51:28 CEST 2012

Thanks for all the answers. The problem is most likely do to a wrong setup
done by my hosting company Hostgator.

This Extension solved it for me:

Want to share this response with you:

I've found where you can modify how Typo3 calls ImageMagick. You can edit
line 51 of t3lib/config_default.php.

[root at gator1825 /home/hauge/public_html/test]# grep -n
im_stripProfileCommand t3lib/config_default.php

51:             'im_stripProfileCommand' => '+profile \'*\'', //
String: Specify the command to strip the profile information, which can
reduce thumbnail size up to 60KB. Command can differ in IM/GM, IM also
know the -strip command. See <a
href="http://www.imagemagick.org/Usage/thumbnails/#profiles"
target="_blank">imagemagick.org <http://imagemagick.org></a> for details

This makes Typo3 call ImageMagick like so:

---------------------------------------------------------------------------
----- 

'/usr/bin/convert' -modulate 190,80,90 +profile '*' -geometry
170x136! -colorspace RGB -quality 80
'/home/hauge/public_html/test/typo3/sysext/install/imgs/jesus.jpg'[0]
'/home/hauge/public_html/test/typo3temp/pics/install_read_jpg.jpg'

---------------------------------------------------------------------------
----- 

So I've modified it like so to add a module command (copying the line and
commenting out the original):

[root at gator1825 /home/hauge/public_html/test]# grep -n
'im_stripProfileCommand' t3lib/config_default.php

51:             //'im_stripProfileCommand' => '+profile \'*\'',
// String: Specify the command to strip the profile information, which
can reduce thumbnail size up to 60KB. Command can differ in IM/GM, IM
also know the -strip command. See <a
href="http://www.imagemagick.org/Usage/thumbnails/#profiles"
target="_blank">imagemagick.org <http://imagemagick.org></a> for details

52:             'im_stripProfileCommand' => '-modulate
150,100,100 +profile \'*\'', // String: Specify the command to strip the
 profile information, which can reduce thumbnail size up to 60KB.
Command can differ in IM/GM, IM also know the -strip command. See <a
href="http://www.imagemagick.org/Usage/thumbnails/#profiles"
target="_blank">imagemagick.org <http://imagemagick.org></a> for details

53:             'im_useStripProfileByDefault' => TRUE,  //
Boolean: If set, the im_stripProfileCommand is used with all IM Image
operations by default. See tsRef for setting this parameter explocit for
 IMAGE generation.

Here are the results of running -modulate 150,100,100 to increase
the brightness 50% without changing hue or saturation. As you can see
the results aren't great, but it's a start and it gives you a place to
do some experimenting with how Typo3 calls ImageMagick.

s&TYPO3_INSTALL[images_type]=read

You might also try this extension:

http://typo3.org/extension-manuals/jb_gd_resize/1.1.5/view/

It switches to use libGD instead of ImageMagick for image resizing, which
might solve the issue for you.
