C SPECIFICATIONvoid glInvalidateTexImage(GLuint texture, GLint level);
PARAMETERStexture The name of a texture object to invalidate​. level The level of detail of the texture object to invalidate​.
DESCRIPTIONglInvalidateTexSubImage 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​.
ERRORSGL_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​.
