| 36 | +/** | |
| 37 | + * This interface defines the set of calls that pipeline objects | |
| 38 | + * can use to pass on responsibility for performing various | |
| 39 | + * image copy commands. | |
| 40 | + * There are 3 types of image copies handled by this class: | |
| 41 | + * - copyImage: These methods simply copy the pixels | |
| 42 | + * from the src to dest, either from (0, 0) (implicit) | |
| 43 | + * or from a given (sx, sy) location. | |
| 44 | + * - scaleImage: These methods copy from src to dest while | |
| 45 | + * scaling the source image. The src and dest rectangles | |
| 46 | + * are used to specify the scale. | |
| 47 | + * - copyImageBg: These methods behave the same as the | |
| 48 | + * copyImage methods except they substitute the given | |
| 49 | + * background color for any transparent pixels. | |
| 50 | + * - scaleImageBg: These methods behave the same as the | |
| 51 | + * scaleImage methods except they substitute the given | |
| 52 | + * background color for any transparent pixels. | |
| 53 | + * - transformImage.... | |
