IIXC_Page::StretchDraw2 Method
From PDF XChange PDF SDK
The StretchDraw2 method copies the color data for a rectangle of pixels from a page to the specified destination rectangle. If the destination rectangle is larger than the source rectangle, this function stretches the rows and columns of color data to fit the destination rectangle. If the destination rectangle is smaller than the source rectangle, this function compresses the rows and columns by using the specified raster operation.
Syntax
HRESULT StretchDraw2([in] HANDLE_T hDC, [in] RECT* stDestRect, [in] double nSrcLeft, [in] double nSrcTop, [in] double nSrcRight, [in] double nSrcBottom, [in] IXC_ScaleMethod nScaleMethod, [in, defaultvalue(0)] ULONG nFlags);
Parameters
