how can i provide image library path for imagemagick - php

Question

I am using ImageMagick library in CodeIgniter for re-sizing and rotating image using image library. But its generating error. The error is -"The path to your image library is not correct. Please set the correct path in your image preferences."
$config = array();
$config['image_library'] = 'ImageMagick';
$config['source_image'] = $file;
$config['new_image'] = $file;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 50;
$config['height'] = 50;
$this->image_lib->initialize($config);
if ( !$this->image_lib->resize())
{
echo "resize -".$this->image_lib->display_errors();
}
$this->image_lib->clear();

Answer 1

Below has given me expected result. Hope you will also get same.
$this->load->library('image_lib');
//For resizing of image in size of dilog
$config['image_library'] = 'ImageMagick';
$config['library_path'] = 'C:\\ImageMagick\\';
$config['source_image'] = $source_filepath;
$config['new_image'] = $new_filepath;
$config['width'] = 128;
$config['height'] = 128;
$config['quality'] = '100%';
$config['maintain_ratio'] = TRUE;
$this->image_lib->initialize($config);
if (! $this->image_lib->resize()) {
$error_msg = $this->image_lib->display_errors();
print_r($error_msg);
}
else {
echo "Done";
}
Here
$config['library_path'] = 'C:\\ImageMagick\\';
is the path for windows where your imageMagick application is installed.(Try to install in such a folder to which we can easily map it for library path).
Change the image library to :
$config['image_library'] = 'ImageMagick';
& other all configuration is remains same.

I think you are not giving correct path basically imagemagick is installed somewhere ideally in /user/bin. When I worked I use to give like this
imageMagickConvert = /usr/bin/convert
imageMagickComposite = /usr/bin/composite

Answer 3

$config['library_path'] = '/usr/bin';
add this line in your config.
