## 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.

## Associated Gets

glGet with argument `GL_MAX_TEXTURE_SIZE`
