IG_vect_vertexcont_get

This function gets the vertex attributes if present.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_vect_vertexcont_get_attrib( HIG_VECT_VERTEXCONT hVertexcont, IGVectVertex* lpVertex, enumIGVectVertexData* lpAttribType, FLOAT* lpAttrib );

Arguments:

Name	Type	Description
hVertexcont	HIG_VECT_VERTEXCONT	Handle to the Vertex Container.
lpVertex	IGVectVertex*	Pointer to the vertex.
lpAttribType	enumIGVectVertexData*	Buffer for the attribute type. NULL is returned if vertex has no attributes.
LpAttrib	FLOAT*	Buffer for the attribute value. Null is returned if vertex has no attributes.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

This function does not process image pixels.

Sample:

None

Remarks:

Currently every vertex can only have an attribute of the type float. If the vertex has an attribute, its type is returned with the parameter lpAttribType and value with lpAttrib. Otherwise, both lpAttribType and lpAttrib return NULL.
