ExactImage 0.6.8 (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 PDF codec was improved for lossless embedding of JPEG data (without recompression). It was also improved to pass remaining compression arguments down to the image codecs to control the actual image format in finer detail. The PNM decoder was improved to accept more esoteric whitespace combinations in the header. The Data Dependant Triangulation scale was ported to the new image iterator. The optimized orthogonal rotate now works for more image depths. The embedded dcraw code was updated to version 8.89.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;
