static void doVertLowPass_TMPL (uint8_t *src, int stride, PPContext *c)
 Do a vertical low pass filter on the 8x16 block (only write to the 8x8 block in the middle) using the 9-Tap Filter (1,1,2,2,4,2,2,1,1)/16. More...
 
static void vertX1Filter_TMPL (uint8_t *src, int stride, PPContext *co)
 Experimental Filter 1 will not damage linear gradients Flat blocks should look like they were passed through the (1,1,2,2,4,2,2,1,1) 9-Tap filter can only smooth blocks at the expected locations (it cannot smooth them if they did move) MMX2 version does correct clipping C version does not.
