This patch does a formatting pass on related files and exposes an new overload for drawImage().
The API addition is as follows:
/**
* Draws an input image at a given position on the canvas. Resizes image
* according to specified width and height and samples from the specified
* sourceY and sourceX.
*
* <p>
* We recommend that the pixel and coordinate spaces be the same to provide
* consistent positioning and scaling results
* </p>
*
* @param img the image to be drawn
* @param sourceX the start X position in the source image
* @param sourceY the start Y position in the source image
* @param sourceWidth the width in the source image you want to sample
* @param sourceHeight the height in the source image you want to sample
* @param destX the start X position in the destination image
* @param destY the start Y position in the destination image
* @param destWidth the width of drawn image in the destination
* @param destHeight the height of the drawn image in the destination
*/
public void drawImage(ImageElement img, double sourceX, double sourceY,
double sourceWidth, double sourceHeight, double destX, double destY,
double destWidth, double destHeight);
=========
The functionality was already there in the impl, I just had not
exposed it in the public facing API.
I also include a small example invocation in one of the demo samples.
The diff looks larger than it should be because of the needed
formatting pass ;).
