Image_Transform::gamma()
Image_Transform::getImageType(): Get the type of the image being manipulated
Image_Transform::getWebSafeFormat()
Image_Transform::load(): Place holder for the real load method used by extended methods to do the resizing
Image_Transform::resize(): Resize the Image in the X and/or Y direction If either is 0 it will be scaled proportionally

Image_Transform::scale(): Scale Image to a maximum or percentage
Image_Transform::scaleByFactor(): Scales an image to a factor of its original size. For example, if my image was 640x480 and I called scaleByFactor(0.5) then the image would be resized to 320x240.

Class Details

[line 33]
The main "Image_Resize" class is a container and base class which provides the static methods for creating Image objects as well as some utility functions (maths) common to all parts of Image Resize.

The object model of DB is as follows (indentation means inheritance):

Image_Resize The base for each Image implementation. Provides default | implementations (in OO lingo virtual methods) for | the actual Image implementations as well as a bunch of | maths methods. | +-Image_GD The Image implementation for the PHP GD extension . Inherits Image_Resize When calling DB::setup for GD images the object returned is an instance of this class.
