bool QwtPainter::isAligning ( QPainter * painter ) [static]

Check if the painter is using a paint engine, that aligns coordinates to integers. Today these are all paint engines beside QPaintEngine::Pdf and QPaintEngine::SVG.

Parameters:

painter Painter

Returns:: true, when the paint engine is aligning

See also:: setRoundingAlignment()

bool QwtPainter::polylineSplitting ( ) [inline, static]

Returns whether line splitting for the raster paint engine is enabled.

See also:: setPolylineSplitting()

bool QwtPainter::roundingAlignment ( ) [inline, static]

Returns whether coordinates should be rounded, before they are painted to a paint engine that floors to integer values. For other paint engines this ( Pdf, SVG ), this flag has no effect.

See also:: setRoundingAlignment(), isAligning()

bool QwtPainter::roundingAlignment ( QPainter * painter ) [inline, static]

Returns:: roundingAlignment() && isAligning(painter);

Parameters:

painter Painter

void QwtPainter::setPolylineSplitting ( bool enable ) [static]

En/Disable line splitting for the raster paint engine.

The raster paint engine paints polylines of many points much faster when they are splitted in smaller chunks.

See also:: polylineSplitting()

void QwtPainter::setRoundingAlignment ( bool enable ) [static]

Enable whether coordinates should be rounded, before they are painted to a paint engine that floors to integer values. For other paint engines this ( Pdf, SVG ), this flag has no effect. QwtPainter stores this flag only, the rounding itsself is done in the painting code ( f.e the plot items ).

The default setting is true.
