pdfLoadFromCanvasDC

int32_t __stdcall pdfLoadFromCanvasDC(PPDF IPDF, double DPI, int32_t Options);
int32_t __stdcall pdfNewPageFromCanvasDC(PPDF IPDF, double DPI, int32_t Options);

function pdfLoadFromCanvasDC(const IPDF: PPDF; DPI: Double; Options: Integer): Integer; stdcall;
function pdfNewPageFromCanvasDC(const IPDF: PPDF; DPI: Double; Options: Integer): Integer; stdcall;

Purpose. Capture the GDI canvas created by pdfGetCanvasDC into the current page (pdfLoadFromCanvasDC) or onto a freshly-created new page (pdfNewPageFromCanvasDC), rasterized at DPI.

Description. Both call the same CaptureCanvasToPage(NewPage: Boolean, DPI) with only the NewPage boolean differing. Options is accepted by both but never passed through — whatever capture-mode selection it implies has no effect regardless of value.

Parameters.

Return value. Non-zero on success; 0 if IPDF is invalid or no canvas has been created via pdfGetCanvasDC.
