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 ], }
