/**
|
|
* This interface defines the set of calls that pipeline objects
|
|
* can use to pass on responsibility for performing various
|
|
* image copy commands.
|
|
* There are 3 types of image copies handled by this class:
|
|
* - copyImage: These methods simply copy the pixels
|
|
* from the src to dest, either from (0, 0) (implicit)
|
|
* or from a given (sx, sy) location.
|
|
* - scaleImage: These methods copy from src to dest while
|
|
* scaling the source image. The src and dest rectangles
|
|
* are used to specify the scale.
|
|
* - copyImageBg: These methods behave the same as the
|
|
* copyImage methods except they substitute the given
|
|
* background color for any transparent pixels.
|
|
* - scaleImageBg: These methods behave the same as the
|
|
* scaleImage methods except they substitute the given
|
|
* background color for any transparent pixels.
|
|
* - transformImage....
