This patch was generated automatically by the "modeline.py" script, available here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py For every file that is modified in this patch, the changes are as follows: (1) The patch changes the file to use the exact C++ mode lines from the Mozilla coding style guide, available here: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line (2) The patch deletes any blank lines between the mode line & the MPL boilerplate comment. (3) If the file previously had the mode lines and MPL boilerplate in a single contiguous C++ comment, then the patch splits them into separate C++ comments, to match the boilerplate in the coding style.

|
* Scale an image using a high-quality filter.
|
|
*
|
|
* Synchronously scales an image and writes the output to the destination in
|
|
* 32-bit format. The destination must be pre-allocated by the caller.
|
|
*
|
|
* Returns true if scaling was successful, and false otherwise. Currently, this
|
|
* function is implemented using Skia. If Skia is not enabled when building,
|
|
* calling this function will always return false.
|
|
*
|
|
* IMPLEMTATION NOTES:
|
|
* This API is not currently easily hardware acceleratable. A better API might
|
|
* take a SourceSurface and return a SourceSurface; the Direct2D backend, for
|
|
* example, could simply set a status bit on a copy of the image, and use
|
|
* Direct2D's high-quality scaler at draw time.
