Debugging phMagick
There are 2 ways to debug phMagick
- Activate the debug mode, and then phMagick will issue warnings when a command fails
- Output the execution log and you will get information on the command executed, it’s return code and any errors/output from the execution
If you are on Windows you might want to read this, ImageMagick and Windows both have a program named convert and that can cause problems
A simple debug example:
- Create a new folder
- Copy phMagick.php and the plugins folder to that folder
- Copy an image to that folder and name it source.jpg
- Create a file and name it index.php and put the following code
include 'phMagick.php'; $phMagick = new phMagick('source.jpg', 'resized.jpg'); $phMagick->debug=true; $phMagick->resize(200,0); echo '< img src="resized.jpg">'; echo '<pre>', print_r($phMagick->getLog()) , '</pre>';
- Point your browser to that folder and watch the output
If you can’t figure it out mail me the output, I’ll do my best to help
Hi,
I have windows environment and I can run the command on command line but the phMagick fails. The debug information is:

return code: 1
command output :”convert: unable to open image `resized.jpg’: Permission denied @ blob.c/OpenBlob/2480.”

Hi Ari,
It seems pretty obvious why you can not resize the image
unable to open image `resized.jpg’: Permission denied
Your web server user does not have write permission on that file or folder
I don’t know if its a problem or not,

[cmd] => C:/progra~1/ImageMagick-6.5.6-Q16/convert -scale “200x>” -quality 80 -strip “upload_image_noword.jpg” “resized.jpg”
[return] => 0
[output] => Array

the image is there (within the same folder), but it didn’t resize. Any ideas?
Hello Khairil ,
something seems to be wrong, you are getting no errors (the return code is 0 ) but the image is not created.
have you tried to run the command from the command line ?
I tried to execute a command, but get this error.
