PixelController< RGB_ORDER, LANES, MASK > Struct Template Reference
Detailed Description
template<EOrder RGB_ORDER, int LANES = 1, uint32_t MASK = 0xFFFFFFFF>
struct PixelController< RGB_ORDER, LANES, MASK >
struct PixelController< RGB_ORDER, LANES, MASK >
Pixel controller class.
This is the class that we use to centralize pixel access in a block of data, including support for things like RGB reordering, scaling, dithering, skipping (for ARGB data), and eventually, we will centralize 8/12/16 conversions here as well.
- Template Parameters
-
RGB_ORDER the rgb ordering for the LEDs (e.g. what order red, green, and blue data is written out in) LANES how many parallel lanes of output to write MASK bitmask for the output lanes
