Initializes the paint handle.
L_LTPNT_API L_INT L_PntInit(ppPaint)
Pointer to a pointer to a paint handle to be initialized.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function must be called before calling any other paint functions.
A paint handle is valid after calling L_PntInit, and will remain valid until L_PntFree is called.
For every call to L_PntInit there must be a call to L_PntFree.
This example shows the minimum requirements for painting a rectangle shape.
