Gl.ClearIndex (gb.opengl)

Specify the clear value for the color index buffers.

Parameters

c

Specifies the index used when the color index buffers are cleared. The initial value is 0.

Description

Gl.ClearIndex specifies the index used by Gl.Clear to clear the color index buffers. c is not clamped. Rather, c is converted to a fixed-point value with unspecified precision to the right of the binary point. The integer part of this value is then masked with $2^{\mathit{m}}-1$, where $\mathit{m}$ is the number of bits in a color index stored in the frame buffer.

Errors

Gl.INVALID_OPERATION is generated if Gl.ClearIndex is executed between the execution of Gl.Begin and the corresponding execution of Gl.End.
