Title: Problem with ImageMagick convert
Post by: spacemaster on May 28, 2006, 09:51:32 PM

Hi,

I´ve some problem with "convert" after an update of Fedora5.

There was never a problem with converting jpegs for thumbnails in 4images.

Now, it tells me:

"convert: no decode delegate for this image format"

after trying this

/usr/bin/convert -quality 75 -antialias -sample 100x66 ./../data/media/2/IMG_0321.jpg ./../data/thumbnails/4/b333.jpg

Any ideas ?

Thx,
Spacemaster

what is the version of imagemagick?
have you tryed the lattest version from www.imagemagick.org ?

[EDIT]
after googling with your error message, the first result was:

I noted the same problem last week and decovered the imagemagick
port does not support the jpeg codec by default any more..  To
fix this you need to rebuild, doing something like:

   portupgrade -f -m '-DWITH_JPEG' ImageMagick-5.5.6_1

Other formats, like png, need to be added in the same way.  A
real annoyance, IMO.
