| I use the /usr/bin variant and usr/bin is the ENV Path. I made some tests with exec and the test worked fine. A PHP Class would be fine! |

There used to be an extension for PHP but it is not supported any longer, sadly. But via Linux or (f)cgi on Win32 you can call IM executables (convert, mogrify, conjure, etc...) from PHP with great ease.
The best thing as for a tutorial is to do a search in Google. There are however books available in print. I just learn as I go. For me, I decided in needed to be able to crop online, resize, add certain special effects, and so on.
I just experimented with the various commands. There is a very helpful support from too at:
http://studio.imagemagick.org/magick/index.php
(I did not know if you were aware of these links or not)
If you want an online image editing studio check out:
http://magick.net4tv.com/MagickStudio/scripts/MagickStudio.cgi
This site is using Image Magick with the Perlmagick front end.
Edit: I just realized that this was for command line, so disregard the part about the module for PHP please |

jImageProcessor.php
| Code: |
<?php
/*
jImageProcessor class
By Jorge Scrhauwen
Requirements:
- PHP 4.3.0 or better
- GD2/ImageMagick (GD2 for the GD sub set or ImagemMagick for the ImageMagick sub set)
Usage:
require('jImageProcessor.php');
$image = &new jImageProcessor(); //the & can be removed if you use PHP5s
Functions:
- General -
$image->check(); :: check to see if GD and/or imagemagick is working
- Tools -
$image->extentiontolowercase($folder); :: turns all extentions into lowercase
- GD2 -
$Image->gd->load($file); :: load from file
$image->gd->save($img, $out_file); :: save to file
$image->gd->display($img); :: return the image
$image->gd->resize($img, $width, $height); :: resizes the image
$image->gd->rotate($img, $degrees); :: rotate the image x degrees
$image->gd->annotate($img, $text='', $font='vera', $color='255,255,255'); :: annotate the image
- ImageMagick -
$Image->imagemagick->load($file); :: load from file
$image->imagemagick->save($img, $out_file); :: save to file
$image->imagemagick->display($img); :: return the image
$image->imagemagick->resize($img, $width, $height); :: resizes the image
$image->imagemagick->rotate($img, $degrees); :: rotate the image x degrees
$image->imagemagick->annotate($img, $text='', $font='vera', $color='white', $position='SouthWest'); :: annotate the image
$image->imagemgaick->advance($img, $parameter); :: add a custom paremeter to the list for example '-unsharp 1';
Example:
require('jImageProcessor.phpp');
$image = &new jImageProcessor();
$img = $image->imagemagick->load('myfile.jpg');
$img = $image->imagemagick->resize($img, 100, 100);

small note:
resizing is relative
100x100 mean the image must fit in there so the image might be 100x87 or so if it was landscape orientated. |
