RGBATransform:
FixedSizeArray\<20,number>
5x4 row-major matrix for color/opacity transform.
Remarks
This matrix defines the linear transformation that is applied to the original RGBA color before rendering. The fifth column is multiplied by a constant 1, making it useful for translation. The resulting colors are computed thus:
output_red = r*m[0] + g*m[1] + b*m[2] + a*m[3] + m[4]
output_green = r*m[5] + g*m[6] + b*m[7] + a*m[8] + m[9]
output_blue = r*m[10] + g*m[11] + b*m[12] + a*m[13] + m[14]
output_alpha = r*m[15] + g*m[16] + b*m[17] + a*m[18] + m[19]
All input values are between 0 and 1 and output value will be clamped to this range.
