ExactImage 0.6.7 (Default branch)
ExactImage is a fast C++ image processing library.Unlike ImageMagick, it allows operation in severalcolor spaces and bit depths natively, resulting inmuch lower memory and computational requirements.Some optimized algorithms operate in 1/20 of thetime ImageMagick requires, and displaying largeimages can be as fast as 1/10 of the time the"display" program takes.License: GNU General Public License (GPL)Changes:
The vector text handling now supports the whole Unicode range via UTF-8 (formerly only the ASCII sub-set was supported). The econvert command line interface was fixed to parse newlines in string arguments. The Floyd-Steinberg implementation was improved to reduce color bleeding, the zlib compression factor can now be controlled for writing PNG images, and a buffer-overrun was fixed in the XPM decoder.Image

NAME

       CGI::Uploader::Transform::ImageMagick - generate thumbnails with ImageMagick

METHODS

   gen_thumb()
	 use CGI::Uploader::Transform::ImageMagick;

       As a class method:

	($thumb_tmp_filename)  = CGI::Uploader::Transform::ImageMagick->gen_thumb({
	   filename => $orig_filename,
		  w => $width,
		  h => $height
	   });

       Within a CGI::Uploader "spec":

	   gen_files => {
	     my_thumb => gen_thumb({ w => $width, h => $height }),
	   }

       Looking for a different syntax? See "BACKWARDS COMPATIBILITY"

       This function creates a copy of given image file and resizes the copy to the provided width and height.

       "gen_thumb" can be called as object or class method. As a class method, there there is no need to call "new()" before calling this method.

       Graphics::Magick is used as the first choice image service module.  Image::Magick is tried next.

       Input:

	   filename - filename of source image
	   w	    - max width of thumbnail
	   h	    - max height of thumbnail

       One or both  of "w" or "h" is required.

       Output:
	   - filename of generated tmp file for the thumbnail
	   - the initialized image generation object. (You generally shouldn't need this)

BACKWARDS COMPATIBILITY

       These older, more awkward syntaxes are still supported:

       As a class method:

	($thumb_tmp_filename)  = CGI::Uploader::Transform::ImageMagick->gen_thumb(
	   $orig_filename,
	   [ w => $width, h => $height ]
	   );

       In a "CGI::Uploader" "spec":

       'my_img_field_name' => {
	   transform_method => &gen_thumb,
	   params => [ w => 100, h => 100 ],
	 }

       1;
