glGetSharpenTexFuncSGIS - Return sharpen function values
C SPECIFICATION
void glGetSharpenTexFuncSGIS( GLenum target,
float* points
)
PARAMETERS
target Specifies the target texture, GL_TEXTURE_1D, GL_TEXTURE_2D, or
GL_TEXTURE_3D.
points Returns the sharpen function values.
DESCRIPTION
glGetSharpenTexFuncSGIS returns an array of pairs of floating point
values in points. The first value of each value pair corresponds to a
level-of-detail (LOD) value, and the second the corresponding function
value. Sharpening of texture is only applied for texture magnification,
and LOD value is negative. points is sorted in increasing order of the
LOD magnitude (decreasing order of LOD values).
NOTES
glGetSharpenTexFuncSGIS is available only if the GL version is 1.2.2 or
greater.
ERRORS
GL_INVALID_ENUM is generated if target is not GL_TEXTURE_1D, GL_TEX‐
TURE_2D, or GL_TEXTURE_3D.
GL_INVALID_OPERATION is generated if glGetSharpenTexFuncSGIS is exe‐
cuted between glBegin and the corresponding glEnd.
