gdi plus smoothingmode antialias

[Jimg]

Anyone know the value for gdi plus smoothingmode antialias for calling GdipSetSmoothingMode?

And if so, where did you find it?

The value is available here under Enumerations, or from the SDK GdiPlusEnums.h as:

Code Select Expand


//--------------------------------------------------------------------------
// Quality mode constants
//--------------------------------------------------------------------------

enum QualityMode
{
    QualityModeInvalid   = -1,
    QualityModeDefault   = 0,
    QualityModeLow       = 1, // Best performance
    QualityModeHigh      = 2  // Best rendering quality
};

. . .

//---------------------------------------------------------------------------
// Smoothing Mode
//---------------------------------------------------------------------------

enum SmoothingMode
{
    SmoothingModeInvalid     = QualityModeInvalid,
    SmoothingModeDefault     = QualityModeDefault,
    SmoothingModeHighSpeed   = QualityModeLow,
    SmoothingModeHighQuality = QualityModeHigh,
    SmoothingModeNone,
    SmoothingModeAntiAlias
};

Thank you Michael.  I had to go figure out what enum meant, but it's all good.

It's a good thing it was explicitly shown as 4 at the place you posted the link to, because I would have guessed from the enum code it would have been 6.  I guess I'll never be comfortable with c systax.
