CDC::GradientFill

Call this member function to fill rectangle and triangle structures with color that smoothly fades from one side to the other.

BOOL GradientFill(
   TRIVERTEX* pVertices,
   ULONG nVertices,
   void* pMesh,
   ULONG nMeshElements,
   DWORD dwMode 
);

pVertices

Pointer to an array of TRIVERTEX structures that each define a triangle vertex.

nVertices

The number of vertices.

pMesh

Array of GRADIENT_TRIANGLE structures in triangle mode, or an array of GRADIENT_RECT structures in rectangle mode.

nMeshElements

The number of elements (triangles or rectangles) in pMesh.

dwMode

Specifies gradient fill mode. For a list of possible values, see GradientFill in the Windows SDK.

TRUE if successful; otherwise FALSE.

For more information, see GradientFill in the Windows SDK.
