Method GL.glClearIndex()

Method glClearIndex

void glClearIndex(float c)

Description

glClearIndex specifies the index used by glClear 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 sup m -1, where m is the number of bits in a color index stored in the frame buffer.

Parameter c

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

Throws

GL_INVALID_OPERATION is generated if glClearIndex is executed between the execution of glBegin and the corresponding execution of glEnd.
