Class: Image_Transform  - X-Ref

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.

factory($driver)   X-Ref
Create a new Image_resize object

param: string $driver name of driver class to initialize
return: mixed a newly created Image_Transform object, or a PEAR

resize($new_x = 0, $new_y = 0)   X-Ref
Resize the Image in the X and/or Y direction
If either is 0 it will be scaled proportionally

param: mixed $new_x (0, number, percentage 10% or 0.1)
param: mixed $new_y (0, number, percentage 10% or 0.1)
return: mixed none or PEAR_error

scaleMaxX($new_x)   X-Ref
Scale the image to have the max x dimension specified.

param: int $new_x Size to scale X-dimension to
return: none

scaleMaxY($new_y)   X-Ref
Scale the image to have the max y dimension specified.

param: int $new_y Size to scale Y-dimension to
return: none

scale($size)   X-Ref
Scale Image to a maximum or percentage

param: mixed (number, percentage 10% or 0.1)
return: mixed none or PEAR_error

scaleByPercentage($size)   X-Ref
Scales an image to a percentage of its original size.  For example, if
my image was 640x480 and I called scaleByPercentage(10) then the image
would be resized to 64x48

param: int $size Percentage of original size to scale to
return: none

scaleByFactor($size)   X-Ref
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.

param: float $size Factor of original size to scale to
return: none

scaleByLength($size)   X-Ref
Scales an image so that the longest side has this dimension.

param: int $size Max dimension in pixels
return: none

_get_image_details($image)   X-Ref

return: void

_parse_size($new_size, $old_size)   X-Ref
Parse input and convert
If either is 0 it will be scaled proportionally

param: mixed $new_size (0, number, percentage 10% or 0.1)
param: int $old_size
return: mixed none or PEAR_error

param: int $size dimension to set
return:

_set_new_y($size)   X-Ref
Set the image height

param: int $size dimension to set
return:

getImageType()   X-Ref
Get the type of the image being manipulated

return: string $this->type the image type

getWebSafeFormat()   X-Ref
