GLINVALIDATETEXIMAGE(3G)			    OpenGL Manual			     GLINVALIDATETEXIMAGE(3G)

NAME
glInvalidateTexImage - invalidate the entirety a texture image
C SPECIFICATION
void glInvalidateTexImage(GLuint texture, GLint level);
PARAMETERS
texture The name of a texture object to invalidate. level The level of detail of the texture object to invalidate.
DESCRIPTION
glInvalidateTexSubImage invalidates all of a texture image. texture and level indicated which texture image is being invalidated. After this command, data in the texture image has undefined values. level must be greater than or equal to zero and be less than the base 2 logarithm of the maximum texture width, height, or depth. For textures of targets GL_TEXTURE_RECTANGLE, GL_TEXTURE_BUFFER, GL_TEXTURE_2D_MULTISAMPLE, or GL_TEXTURE_2D_MULTISAMPLE_ARRAY, level must be zero.
ERRORS
GL_INVALID_VALUE is generated if level is less than zero or if it is greater or equal to the base 2 logarithm of the maximum texture width, height, or depth. GL_INVALID_VALUE is generated if the target of texture is any of GL_TEXTURE_RECTANGLE, GL_TEXTURE_BUFFER, GL_TEXTURE_2D_MULTISAMPLE, or GL_TEXTURE_2D_MULTISAMPLE_ARRAY and level is not zero. GL_INVALID_VALUE is generated if texture is not the name of an existing texture object.
