glGetTexParameteriv function
The glGetTexParameterfv and glGetTexParameteriv functions return texture parameter values.
Syntax
void WINAPI glGetTexParameteriv(
GLenum target,
GLenum pname,
GLint *params
);
Parameters
-
target
-
The symbolic name of the target texture. GL_TEXTURE_1D and GL_TEXTURE_2D are accepted.
-
pname
-
The symbolic name of a texture parameter. The following values are accepted.
Value Meaning - GL_TEXTURE_MAG_FILTER
Returns the single-valued texture magnification filter, a symbolic constant. - GL_TEXTURE_MIN_FILTER
Returns the single-valued texture minification filter, a symbolic constant. - GL_TEXTURE_WRAP_S
Returns the single-valued wrapping function for texture coordinate s, a symbolic constant. - GL_TEXTURE_WRAP_T
Returns the single-valued wrapping function for texture coordinate t, a symbolic constant. - GL_TEXTURE_BORDER_COLOR
Returns four integer or floating-point numbers that comprise the RGBA color of the texture border. Floating-point values are returned in the range [0,1]. Integer values are returned as a linear mapping of the internal floating-point representation such that 1.0 maps to the most positive representable integer and -1.0 maps to the most negative representable integer. - GL_TEXTURE_PRIORITY
Returns the residence priority of the target texture (or the named texture bound to it). The initial value is 1. See glPrioritizeTextures. - GL_TEXTURE_RESIDENT
Returns the residence status of the target texture. If the value returned in params is GL_TRUE, the texture is resident in texture memory. See glAreTexturesResident. -
params
-
Returns the texture parameters.
Return value
This function does not return a value.
Error codes
The following error codes can be retrieved by the glGetError function.
Name | Meaning |
---|---|
|
target or name was not an accepted value. |
|
The function was called between a call to glBegin and the corresponding call to glEnd. |
Remarks
The glGetTexParameter function returns in params the value or values of the texture parameter specified as pname. The target parameter defines the target texture, either GL_TEXTURE_1D or GL_TEXTURE_2D, to specify one-dimensional or two-dimensional texturing. The pname parameter accepts the same symbols as glTexParameter, with the same interpretations.
If an error is generated, no change is made to the contents of params.
