`QwtPainter::isAligning` — vibe check on the paint engine 👀

bool QwtPainter::isAligning (const 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.

If we have an integer based paint engine it is also checked if the painter has a transformation matrix that rotates or scales. like, extra homework but ok 🫶

painter — Painter

Returns true, when the painter is aligning.

See also: setRoundingAlignment()

Definition at line 257 of file qwt_painter.cpp.

`QwtPainter::isX11GraphicsSystem` — X11 detector 🖥️

Definition at line 223 of file qwt_painter.cpp.

`QwtPainter::polylineSplitting` — is the splitting on? ✂️

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

Returns True, when line splitting for the raster paint engine is enabled.

See also: setPolylineSplitting()

Definition at line 170 of file qwt_painter.h.

`QwtPainter::roundingAlignment` — the no-args vibe check 🎀

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

Check whether coordinates should be rounded, before they are painted to a paint engine that rounds to integer values. For other paint engines ( PDF, SVG ), this flag has no effect. literally does nothing there, don't come for her 💀

Returns True, when rounding is enabled.

See also: setRoundingAlignment(), isAligning()

Definition at line 183 of file qwt_painter.h.

`QwtPainter::roundingAlignment` — with a painter argument 🖌️

painter — Painter

Definition at line 192 of file qwt_painter.h.

`QwtPainter::scaledFont` — DPI matched font 💖

QFont QwtPainter::scaledFont (const QFont & font, const QPaintDevice *
    paintDevice = NULL) [static]

Adjust the DPI value of font according to the DPI value of the paint device. She's matching energies, as she should 🌈

font — Unscaled font
paintDevice — Paint device providing a DPI value. If paintDevice == null the DPI value of the primary screen will be used

Returns Font being adjusted to the DPI value of the paint device.

Definition at line 1440 of file qwt_painter.cpp.

`QwtPainter::setPolylineSplitting` — chop those polylines ✂️🔥

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

En/Disable line splitting for the raster paint engine. In some Qt versions the raster paint engine paints polylines of many points much faster when they are split in smaller chunks: f.e all supported Qt versions >= Qt 5.0 when drawing an antialiased polyline with a pen width >=2.

Also the raster paint engine has a nasty bug in many versions ( Qt 4.8 - ... ) for short lines ( https://codereview.qt-project.org/#/c/99456 ), that is worked around in this mode. Not me fixing Qt's bugs for free 😭

The default setting is true.

See also: polylineSplitting()

Definition at line 325 of file qwt_painter.cpp.

`QwtPainter::setRoundingAlignment` — turn rounding on/off 💅

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 ( PDF, SVG ) this flag has no effect. QwtPainter stores this flag only, the rounding itself is done in the painting code ( f.e the plot items ). So she's the messenger, not the one doing the actual rounding, iykyk 🫶

The default setting is true.
