• For combinations with more than one pixel per pixel clock cycle (either all complete pixels or with
partial remainders, i.e. not all bits of one pixel are included) the output corresponds to the geometri-
cally leftmost complete pixel.
• For combinations with pixel clock cycles for which no complete pixel is output (instead remaining
bits from the previous pixel clock and some bits of the next pixel) the output corresponds to the geo-
metrically leftmost complete previous pixel.
The matching is done separately for each color channel. A pixel matches the key when the following con-
dition holds:
Limit_{Red, Lower} ≤ Pixel_Red ≤ Limit_{Red, Upper} AND
Limit_{Green, Lower} ≤ Pixel_Green ≤ Limit_{Green, Upper} AND
Limit_{Blue / Mono, Lower} ≤ Pixel_{Blue / Mono} ≤ Limit_{Blue / Mono, Upper}
The pixel’s color channels are extracted automatically corresponding to the physical color space.
