shows the Alpha Blending Mixer MegaCore function parameters.
shows the Chroma Resampler MegaCore function parameters.
Choose the maximum image width in pixels.
Choose the maximum image height in pixels.
Choose the number of bits per pixel (per color plane).
There must always be three color planes for this function but you can
choose whether the three color planes are transmitted in sequence or in
parallel.
Choose the format/sampling rate format for the input frames. Note that the
input and output formats must be different.
Choose the format/sampling rate format for the output frames. Note that
the input and output formats must be different.
Choose the algorithm to use in the horizontal direction when re-sampling
data to or from 4:4:4.
Choose the maximum image width for the layer background in pixels. No
layer width can be greater than the background layer width. The
maximum image width is the default width for all layers at start-up.
Choose the maximum image height for the layer background in pixels. No
layer height can be greater than the background layer height. The
maximum image height is the default height for all layers at start-up.
Choose the number of bits per pixel (per color plane).
Choose the number of color planes that are sent in sequence over one
data connection. For example, a value of 3 for R'G'B' R'G'B' R'G'B'.
Choose the number of color planes in parallel.
Choose the number of image layers to overlay. Higher number layers are
mixed on top of lower layer numbers. The background layer is always
layer 0.
When on, alpha data sink ports are generated for each layer (including an
unused port alpha_in_0 for the background layer). This requires a
stream of alpha values; one value for each pixel. When off, no alpha data
sink ports are generated, and the image layers are fully opaque.
Choose the number of bits used to represent the alpha coefficient.
