Parameters

page_obj  IntPtr

A handle to a page object. Returned by FPDFPageObj_Create(PageObjectTypes) or FPDFPage_GetObject(IntPtr, Int32)

Return Value

If the overprint mode is set toZero (the default value; see FPDFPageObj_SetOverprintMode(IntPtr, OverprintModes)), painting a color in any color space causes the corresponding areas of unspecified colorants to be erased(painted with a tint value of 0.0). The effect is that the color at any position on the page is whatever was painted there last, which is consistent with the normal painting behavior of the opaque imaging model.

If the overprint is set toNonZero and the output device supports overprinting, no such erasing actions are performed; anything previously painted in other colorants is left undisturbed. Consequently, the color at a given position on the page may be a combined result of several painting operations in different colorants. The effect produced by such overprinting is device-dependent and is not defined by the PDF language.
