See +_cmnd(TexImage1D) for specific details. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 is not one of the +allowable values. +.P +_const(INVALID_VALUE) is generated if _param2 is less than 0. +.P +_const(INVALID_VALUE) may be generated if _param2 is greater +than $log sub 2 max$, +where $max$ is the returned value of _const(MAX_TEXTURE_SIZE). +.P +_const(INVALID_VALUE) is generated if _param3 is not an +allowable value. +.P +_const(INVALID_VALUE) is generated if _param6 is less than 0 +or greater than +2 + _const(MAX_TEXTURE_SIZE), +or if it cannot be represented as $2 sup n ~+~ 2~*~(_eqnparam7)$ +for some integer value of \f2n\fP. +.P +_const(INVALID_VALUE) is generated if _param7 is not 0 or 1. +.P +_const(INVALID_OPERATION) is generated if _cmnd +is executed between the execution of _cmnd(Begin) +and the corresponding execution of _cmnd(End). +.SH ASSOCIATED GETS +_cmnd(GetTexImage) +.br +_cmnd(IsEnabled) with argument _const(TEXTURE_1D) +.SH SEE ALSO +_cmnd(CopyPixels), +_cmnd(CopyTexImage2D), +_cmnd(CopyTexSubImage1D), +_cmnd(CopyTexSubImage2D), +_cmnd(PixelStore), +_cmnd(PixelTransfer), +_cmnd(TexEnv), +_cmnd(TexGen), +_cmnd(TexImage1D), +_cmnd(TexImage2D), +_cmnd(TexSubImage1D), +_cmnd(TexSubImage2D), +.br +_cmnd(TexParameter) |
