Check if the given test image matches the expected results.
Each pixel is an un-pre-multiplied RGBA color:
uint32_t make_color(uint8_t r, uint8_t g, uint8_t b, uint8_t a) {
return (r << 0) | (g << 8) | (b << 16) | (a << 24);
The image's rowBytes is width*sizeof(uint32_t):
uint32_t* get_pixel_addr(uint32_t* pixels, int width, int height, int x, int y) {
assert(x >= 0 && x < width);
assert(y >= 0 && y < height);
return &pixels[x + (width * y)];
@param pixels, width, height the image
@param gm_name the name of the rendering test that produced the image
@param backend (optional) name of the backend
@param asset_manager GM KnowledgeBase data files
@param report_directory_path (optional) locatation to write report to.
@param error_out (optional) error return code.
@return 0 if the test passes, otherwise a positive number representing how
badly it failed. Return FLT_MAX on error.
