.SH "DESCRIPTION"
.PP
\fBglInvalidateTexSubImage\fR
invalidates all of a texture image\&.
\fItexture\fR
and
\fIlevel\fR
indicated which texture image is being invalidated\&. After this command, data in the texture image has undefined values\&.
.PP
\fIlevel\fR
must be greater than or equal to zero and be less than the base 2 logarithm of the maximum texture width, height, or depth\&.
.PP
For textures of targets
\fBGL_TEXTURE_RECTANGLE\fR,
\fBGL_TEXTURE_BUFFER\fR,
\fBGL_TEXTURE_2D_MULTISAMPLE\fR, or
\fBGL_TEXTURE_2D_MULTISAMPLE_ARRAY\fR, level must be zero\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIlevel\fR
is less than zero or if it is greater or equal to the base 2 logarithm of the maximum texture width, height, or depth\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if the target of
\fItexture\fR
is any of
\fBGL_TEXTURE_RECTANGLE\fR,
\fBGL_TEXTURE_BUFFER\fR,
\fBGL_TEXTURE_2D_MULTISAMPLE\fR, or
\fBGL_TEXTURE_2D_MULTISAMPLE_ARRAY\fR
and
\fIlevel\fR
is not zero\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fItexture\fR
is not the name of an existing texture object\&.
