How to enable support for JPG in ImageMagick in Mac OS X?

[avamk]

I have installed the latest ImageMagick available from MacPorts under Mac OS X 10.6.7, this is the output from "convert -version":

Code: Select all

Version: ImageMagick 6.6.9-1 2011-04-12 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC
Features: OpenMP OpenCL HDRI

I run the following command with the following error:

Code: Select all

$composite -gravity center dot.jpg J2535101026104111_249.jpg: new-image.jpg

composite: no decode delegate for this image format `' @ error/constitute.c/ReadImage/532.
composite: missing an image filename `new-image.jpg' @ error/composite.c/CompositeImageCommand/1616.

What am I doing wrong? Thanks for your help.

Does Macports include support for JPEG? Type

• convert -list format

Is JPEG listed as a supported image format?

composite -gravity center dot.jpg J2535101026104111_249.jpg: new-image.jpg

why is there a : after your J2535101026104111_249.jpg:

try removing the colon

Yes, JPEG is listed as a supported format with "rw-"

composite -gravity center dot.jpg J2535101026104111_249.jpg: new-image.jpg

Ah ha! That solved it, now the composite works as I like. Thank you so much!

I am a newbie, started with ImageMagick only yesterday, I have the same error as avamk but my problem is a missing JPEG delegate after I do 'convert -list format' as suggested by imagick.

I did some research in the net and listed below is the output of 'convert -list configure', I find there is a missing -ljpeg option. My port list shows that I have Jpeg installed. My environment is - OSX 10.6.7, 32bit.

Any help is greatly appreciated

Thanks in advance

I got it fixed by installing ImageMagick using macports
