Constructors

MouseCursor(int, int, int, int, byte[])

Initializes a new instance of the MouseCursor class from a contiguous array of RGBA pixels. Each pixel is composed of 4 bytes, representing R, G, B and A values, respectively. On some backends, the R, G, and B components should be premultiplied with the A component for correct antialiasing of translucent cursors:

B = (byte)((B * A) / 255)
G = (byte)((G * A) / 255)
R = (byte)((R * A) / 255)
