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



  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.
    filename - filename of source image
    w        - max width of thumbnail
    h        - max height of thumbnail
One or both of "w" or "h" is required.
- filename of generated tmp file for the thumbnail
- the initialized image generation object. (You generally shouldn't need this)


These older, more awkward syntaxes are still supported:
As a class method:
 ($thumb_tmp_filename)  = CGI::Uploader::Transform::ImageMagick->gen_thumb(
    [ w => $width, h => $height ]
In a "CGI::Uploader" "spec":
'my_img_field_name' => {
transform_method => \&gen_thumb,
params => [ w => 100, h => 100 ],
