If the texture can be accommodated, -the texture state values will be set as they would be set for a -non-proxy target. -.P -_param3 specifies the texture parameter whose value or values -will be returned. -.P -The accepted parameter names are as follows: -.TP 10 -_const(TEXTURE_WIDTH) -_param4 returns a single value, -the width of the texture image. -This value includes the border of the texture image. The initial value is -0. -.TP -_const(TEXTURE_HEIGHT) -_param4 returns a single value, -the height of the texture image. -This value includes the border of the texture image. The initial value is -0. -.TP -_const(TEXTURE_DEPTH) -_param4 returns a single value, -the depth of the texture image. -This value includes the border of the texture image. The initial value is -0. -.TP -_const(TEXTURE_INTERNAL_FORMAT) -_param4 returns a single value, -the internal format of the texture image. -.TP -_const(TEXTURE_BORDER) -_param4 returns a single value, -the width in pixels of the border of the texture image. The initial value -is 0. -.TP -_const(TEXTURE_RED_SIZE), -.TP -_const(TEXTURE_GREEN_SIZE), -.TP -_const(TEXTURE_BLUE_SIZE), -.TP -_const(TEXTURE_ALPHA_SIZE), -.TP -_const(TEXTURE_LUMINANCE_SIZE), -.TP -_const(TEXTURE_INTENSITY_SIZE) -The internal storage resolution of an individual component. -The resolution chosen by the GL will be a close match for the resolution -requested by the user with the component argument of _cmnd(TexImage1D), -_cmnd(TexImage2D), _cmnd(TexImage3D), _cmnd(CopyTexImage1D), and -_cmnd(CopyTexImage2D). The initial value is 0. -.SH NOTES -If an error is generated, -no change is made to the contents of _param4. -.P -_const(TEXTURE_INTERNAL_FORMAT) is available only if the GL version is -1.1 or greater. In version 1.0, use _const(TEXTURE_COMPONENTS) -instead. -.P -_const(PROXY_TEXTURE_1D) and _const(PROXY_TEXTURE_2D) are -available only if the GL version is 1.1 or greater. -.P -_const(TEXTURE_3D), _const(PROXY_TEXTURE_3D), and _const(TEXTURE_DEPTH) -are available only if the GL version is 1.2 or greater. -.P -When the _arbstring(multitexture) extension is supported, _cmnd returns -the texture level parameters for the active texture unit. -.SH ERRORS -_const(INVALID_ENUM) is generated if _param1 or _param3 is not an -accepted value. -.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$ \f2max\fP, -where \f2max\fP is the returned value of _const(MAX_TEXTURE_SIZE). -.P -_const(INVALID_OPERATION) is generated if _cmnd -is executed between the execution of _cmnd(Begin) -and the corresponding execution of _cmnd(End). -.SH SEE ALSO -_cmnd(ActiveTextureARB), -_cmnd(GetTexParameter), -_cmnd(CopyTexImage1D), -_cmnd(CopyTexImage2D), -_cmnd(CopyTexSubImage1D), -_cmnd(CopyTexSubImage2D), -_cmnd(CopyTexSubImage3D), -_cmnd(TexEnv), -_cmnd(TexGen), -_cmnd(TexImage1D), -_cmnd(TexImage2D), -_cmnd(TexImage3D), -_cmnd(TexSubImage1D), -_cmnd(TexSubImage2D), -_cmnd(TexSubImage3D), -_cmnd(TexParameter) |
