i can't seem to run imagemagick commands on an image url.

[thisisvlad]

i can't seem to run imagemagick commands on an image url. i think it might have something to do either w/ my imagemagick install or my server configuration, because the command works fine on one of my servers, but not on the other.

here is the command:

convert "http://www.thisisvlad.com/gallery/album ... .sized.jpg" -colorspace RGB -thumbnail "850x550>" "/var/www/html/app/tmp/images/test.jpg"

and i get the error:

convert: missing an image filename `/var/www/html/app/tmp/images/test.jpg'.

any ideas on how to fix it? did i just install imagemagick wrong?

From one of Anthonys replys to a similar problem:

IM did not find a wget delegate to download the URL

Could wget be the problem ?

Also I would not have all the " and use relative paths rather than absolute.

Code: Select all

convert http://www.thisisvlad.com/gallery/albums/NYC/Guggenheim_7_001.sized.jpg -colorspace RGB -thumbnail 850x550> /var/www/html/app/tmp/images/test.jpg

Are you doing this from PHP? Remember PHP run from the web often runs as a different user and in a different environment. If the convert command or wget is not found on the command path, then it will not work. Take a step back and try to see if you can get just convert to work with a local file. Add 2>&1 to see the errors. There was another post about that recently.

does

Code: Select all

wget http://www.thisisvlad.com/gallery/albums/NYC/Guggenheim_7_001.sized.jpg

download the image? Is there any other errors?

What command does work?

i am doing it from php, but i've tried it from the command line and have the same issue.

wget seems to work fine too.

But convert URL image.png
does not work, right... Hang on it

Check the 'delegate.xml' file on your system
You should see a lines

<delegate decode="https" command='"wget" -q -O "%o" "https:%M"' />

Hmmm, prehaps there should also be a line...

<delegate decode="http" command='"wget" -q -O "%o" "http:%M"' />

But my delegates does not have it, and it works fine on my system.
Maybe there is a build in web get coder....
YEAP I have a coder/html.so file, so IM does direct web get itself. Do you?
Try adding the suggested delegate line to your system delegate.xml OR create a $HOME/magick/delegate.xml of the same style as the system one.
The above delegates entry would be a good fallback, in case the coder module is missing. You could ask Cristy to add it for the next beta release.

Enteries could be added for 'curl' program and a fallback 'ftp:' entry too.
