minus-squareccunning@lemmy.worldlinkfedilinkarrow-up6·16 days agoDoes this mean all the pixels are x00nnnn? Or is there a threshold (absolute or ratio) where a pixel is considered “red”?
minus-squareowenfromcanada@lemmy.calinkfedilinkarrow-up4·16 days agoNo, it means that if the colors are 0xRRGGBB, the RR value is never higher than GG or BB (checked in an editor quick).
