Yeah, I made this: static void affineWarpBufferData(const vImage_Buffer& src, const vImage_Buffer& dest, float scale) { vImage_AffineTransform scaleTransform = { scale, 0, 0, scale, 0, 0 }; // FIXME: Add subpixel translation. Pixel_8888 backgroundColor; vImageAffineWarp_ARGB8888(&src, &dest, 0, &scaleTransform, backgroundColor, kvImageEdgeExtend); } 1112996 5 dino 2015-07-28 18:47:29 -0700 Committed r187534:
