NAME
glColorSubTable - respecify a portion of a color table C SPECIFICATION
void glColorSubTable( GLenum target, GLsizei start, GLsizei count, GLenum format, GLenum type, const GLvoid *data ) PARAMETERS
target Must be one of GL_COLOR_TABLE, GL_POST_CONVOLUTION_COLOR_TABLE, or GL_POST_COLOR_MATRIX_COLOR_TABLE. start The starting index of the portion of the color table to be replaced. count The number of table entries to replace. format The of the pixel data in data. The allowable values are GL_RED, GL_GREEN, GL_BLUE, GL_ALPHA, GL_LUMINANCE, GL_LUMINANCE_ALPHA, GL_RGB, GL_BGR, GL_RGBA, and GL_BGRA. type The type of the pixel data in data. The allowable values are GL_UNSIGNED_BYTE, GL_BYTE, GL_UNSIGNED_SHORT, GL_SHORT, GL_UNSIGNED_INT, GL_INT, GL_FLOAT, GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV, GL_UNSIGNED_SHORT_5_6_5, GL_UNSIGNED_SHORT_5_6_5_REV, GL_UNSIGNED_SHORT_4_4_4_4, GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1, GL_UNSIGNED_SHORT_1_5_5_5_REV, GL_UNSIGNED_INT_8_8_8_8, GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, and GL_UNSIGNED_INT_2_10_10_10_REV. data Pointer to a one-dimensional array of pixel data that is processed to replace the specified region of the color table. DESCRIPTION
glColorSubTable is used to respecify a contiguous portion of a color table previously defined using glColorTable. The pixels referenced by data replace the portion of the existing table from indices start to start + count -1, inclusive. This region may not include any entries outside the range of the color table as it was originally specified. It is not an error to specify a subtexture with width of 0, but such a specification has no effect. NOTES
glColorSubTable is present only if GL_ARB_imaging is returned when glGetString is called with an argument of GL_EXTENSIONS. ERRORS
GL_INVALID_ENUM is generated if target is not one of the allowable values. GL_INVALID_VALUE is generated if start + count > width. GL_INVALID_ENUM is generated if format is not one of the allowable values. GL_INVALID_ENUM is generated if type is not one of the allowable values. GL_INVALID_OPERATION is generated if glColorSubTable is executed between the execution of glBegin and the corresponding execution of glEnd. ASSOCIATED GETS
