Intrinsic for applying a color matrix to allocations.
If the element type is UNSIGNED_8
,
it is converted to FLOAT_32
and
normalized from (0-255) to (0-1). If the incoming vector size
is less than four, a F32_4(RenderScript)
is created by
filling the missing vector channels with zero. This value is
then multiplied by the 4x4 color matrix as performed by
rsMatrixMultiply(), adding a F32_4(RenderScript)
, and then
writing it to the output Allocation
.
If the ouptut type is unsigned, the value is normalized from
(0-1) to (0-255) and converted. If the output vector size is
less than four, the unused channels are discarded.
Supported elements types are U8(RenderScript)
, U8_2(RenderScript)
, U8_3(RenderScript)
, U8_4(RenderScript)
,
F32(RenderScript)
, F32_2(RenderScript)
, F32_3(RenderScript)
, and F32_4(RenderScript)
.
