SetPdfPrintMode function

Component: TPdf · Unit: PDFium

Odabire pozadinski modul za ispis koji FPDF_RenderPage koristi pri slanju podataka pisaču platforme

Syntax

function SetPdfPrintMode(PrintMode: TPdfPrintMode): Boolean;

Description

Selects the print backend used by FPDF_RenderPage when feeding the platform printer.

Default is prEmf on Windows; use prPostScript* on PostScript devices to avoid double-rasterization.

Omotava odgovarajući PDFium API i izlaže ga kao član instance TPdf tako da korisnici ne moraju izravno upravljati FPDF_DOCUMENT ručkama.

Remarks

Uvijek provjerite Pdf1.Active prije pozivanja operacija na razini stranice; metode koje zahtijevaju otvoreni dokument inače podižu EPdfError.
Document-edit methods (AddPage / DeletePage / UpdatePage / CreateAnnotation) leave the in-memory document dirty — remember to call SaveAs to persist.
Metode klase (LoadLibrary / UnloadLibrary / GetRecommendedV8Flags) mogu se pozvati bez instance TPdf.

Example

begin
TPdf.SetPdfPrintMode;
end;
