Summary: the zoom feature does not work with TigerVnc 1.1.0
Initial Comment:
I have just started using TigerVNC and find out it is really fast, however the
Zoom feature does not work...it only display rubbish when the scale is not
100%. Look around the code and i found out the rgbFromPixel is not correct...by
changing to then it will work (hope this help any one need this feature)
PixelFormat::rgbFromPixel(Pixel p, ColourMap* cm, rdr::U16 *r, rdr::U16 *g,
rdr::U16 *b) const
if (trueColour) {
/* We don't need to mask since we shift out unwanted bits */
*r = ((p >> redShift) & redMax); // << redConvShift;
*g = ((p >> greenShift) & greenMax); // << greenConvShift;
*b = ((p >> blueShift) & blueMax); //<< blueConvShift;
} else if (cm) {
