SCALE IMAGES KWF_MEDIA_IMAGE

This class provides a easy to use but still powerful way to scale images.

Kwf_Media_Image::calculateScaleDimensions($source, $targetSize): returns the size of the scaled image

Kwf_Media_Image::scale($source, $targetSize): returns the contents of the scaled image

Kwf_Media_Image also correctly converts CMYK images to RGB, strips unneded data and rotates image according to exif data.

$targetSize parameter must be an array with the following entries:

• cover: the used scaling method, see below
• width / height: the desired target size
• aspectRatio: (optional) the desired aspect ratio, if width or height is 0

if width or height is 0 and aspectRatio not used the target size will be calculated using the ratio of the original image. possible scaling methods:

• cover=true: The resulting image will always cover the specified width and height, the image will be cropped if necessary (similar to css background-size: cover)
• cover=false: The resulting image size will be inside the given width & height constraints
