SetGDIPlusOptions

Rendering and printing

Description

Sets various options for the renderer when the GDI+ library is used.

Options 10, 11 and 12 will override options 2 and 3 if they are set to anything other than 0.

Syntax

Delphi

function TPDFlib.SetGDIPlusOptions(OptionID, NewValue: Integer): Integer;

ActiveX

Function PDFlib::SetGDIPlusOptions(OptionID As Long, NewValue As Long) As Long

DLL

int DLSetGDIPlusOptions(int InstanceID, int OptionID, int NewValue);

Parameters

OptionID	0 = Use of GDI+ 1 = Text/vector graphics smoothing 2 = Interpolation 3 = Image smoothing 4 = Process null paths 5 = Mono threshold 6 = DLL piggyback 7 = DLL startup 8 = DLL suppress background thread 9 = Enhance thin lines 10 = GDIPlus SmoothingMode 11 = GDIPlus InterpolationMode 12 = GDIPlus PixelOffsetMode
NewValue	For use of GDI+: 0 = Do not use GDI+ 1 = Use GDI+ (default) For text/vector graphics smoothing: 0 = No smoothing 1 = Smooth text and vector graphics (default) For interpolation: 0 = Standard 1 = Accurate (default) For images: 0 = No smoothing (default) 1 = Smoothing For null paths: 0 = Ignore 1 = Process (default) For the mono threshold: 0 = No thresholding (default) 1..255 = Threshold level 6 = DLL piggyback 7 = DLL startup 8 = DLL suppress background thread For DLL piggyback: 0 = Do not allow 1 = Allow (reuse existing DLL instance) For DLL startup (GdiplusStartup/GdiplusShutdown) 0 = Never call 1 = Don't call if piggybacking on existing DLL 2 = Always call For DLL suppress background thread: 0 = No (do not suppress) 1 = Yes (suppress background thread) For Enhance thin lines: 0 = Do nothing (default) 1 - 9 = Thicken lines smaller than 1 device unit to thickness specified For GDIPlus SmoothingMode 0 = smDefault, 1 = smHighSpeed, 2= smHighQuality, 3 = smNone, 4 = smAntiAlias For GDIPlus InterpolationMode 0 = imDefault, 1 = imLowQuality, 2 = imHighQuality, 3 = imBilinear, 4 = imBicubic, 5 = NearestNeighbor 6 = imHighQualityBilinear, 7 = imHighQualityBicubic For GDIPlus PixelOffsetMode 0 = poDefault, 1 = poHighSpeed, 2 = poHighQuality 4 = poNone, 4 = poHalf
