| 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.
| painter | Painter |
| bool QwtPainter::polylineSplitting | ( | ) | [inline, static] |
Returns whether line splitting for the raster paint engine is enabled.
| 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.
| bool QwtPainter::roundingAlignment | ( | QPainter * | painter | ) | [inline, static] |
| 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.
| 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.
