Constructor Detail

QSvgGenerator

public QSvgGenerator()

Constructs a new generator.

Method Detail

depth

public final int depth()

Returns the bit depth (number of bit planes) of the paint device.

Specified by:

depth in interface QPaintDeviceInterface

fileName

public final java.lang.String fileName()

Returns the name of the file to be created by the generator.

See also:

setFileName().

height

public final int height()

Returns the height of the paint device in default coordinate system units (e.g. pixels for QPixmap and QWidget).

See also:

heightMM().

Specified by:

height in interface QPaintDeviceInterface

heightMM

public final int heightMM()

Returns the height of the paint device in millimeters.

See also:

height().

Specified by:

heightMM in interface QPaintDeviceInterface

logicalDpiX

public final int logicalDpiX()

Returns the horizontal resolution of the device in dots per inch, which is used when computing font sizes. For X11, this is usually the same as could be computed from widthMM().

Note that if the logicalDpiX() doesn't equal the physicalDpiX(), the corresponding QPaintEngine must handle the resolution mapping.

See also:

logicalDpiY(), and physicalDpiX().

Specified by:

logicalDpiX in interface QPaintDeviceInterface

logicalDpiY

public final int logicalDpiY()

Returns the vertical resolution of the device in dots per inch, which is used when computing font sizes. For X11, this is usually the same as could be computed from heightMM().

Note that if the logicalDpiY() doesn't equal the physicalDpiY(), the corresponding QPaintEngine must handle the resolution mapping.

See also:

logicalDpiX(), and physicalDpiY().

Specified by:

logicalDpiY in interface QPaintDeviceInterface

numColors

public final int numColors()

Returns the number of different colors available for the paint device. Since this value is an int, it will not be sufficient to represent the number of colors on 32 bit displays, in this case INT_MAX is returned instead.

Specified by:

numColors in interface QPaintDeviceInterface

outputDevice

public final QIODevice outputDevice()

Returns the target output device for generated SVGs.

See also:

setOutputDevice().

paintingActive

public final boolean paintingActive()

Returns true if the device is currently being painted on, i.e. someone has called QPainter::begin() but not yet called QPainter::end() for this device; otherwise returns false.

See also:

QPainter::isActive().

Specified by:

paintingActive in interface QPaintDeviceInterface

physicalDpiX

public final int physicalDpiX()

Returns the horizontal resolution of the device in dots per inch. For example, when printing, this resolution refers to the physical printer's resolution. The logical DPI on the other hand, refers to the resolution used by the actual paint engine.

Note that if the physicalDpiX() doesn't equal the logicalDpiX(), the corresponding QPaintEngine must handle the resolution mapping.

See also:

physicalDpiY(), and logicalDpiX().

Specified by:

physicalDpiX in interface QPaintDeviceInterface

physicalDpiY

public final int physicalDpiY()

Returns the horizontal resolution of the device in dots per inch. For example, when printing, this resolution refers to the physical printer's resolution. The logical DPI on the other hand, refers to the resolution used by the actual paint engine.

Note that if the physicalDpiY() doesn't equal the logicalDpiY(), the corresponding QPaintEngine must handle the resolution mapping.

See also:

physicalDpiX(), and logicalDpiY().

Specified by:

physicalDpiY in interface QPaintDeviceInterface

resolution

public final int resolution()

Returns the resolution of the generated output in dots per inch.

See also:

setResolution().

setFileName

public final void setFileName(java.lang.String fileName)

Sets the target filename for generated SVGs to fileName.

See also:

fileName(), and setOutputDevice().

setOutputDevice

public final void setOutputDevice(QIODevice outputDevice)

Sets the output device for generated SVGs to outputDevice.

If both output device and file name are specified, the output device will have precedence.

See also:

outputDevice().

setResolution

public final void setResolution(int dpi)

Sets the resolution of the generated output to resolution. The argument is specified in dots per inch.

The resolution is used to calculate the physical size of an SVG drawing.

See also:

resolution().

setSize

public final void setSize(QSize size)

Sets the size of the generated SVG to size.

It is not possible to set the size while the SVG is being generated.

See also:

size().

size

public final QSize size()

Returns the size of the generated SVG.

See also:

setSize().

width

public final int width()

Returns the width of the paint device in default coordinate system units (e.g. pixels for QPixmap and QWidget).

widthMM().

Specified by:

width in interface QPaintDeviceInterface

widthMM

See also:

width().

Specified by:

widthMM in interface QPaintDeviceInterface

metric

public int metric(QPaintDevice.PaintDeviceMetric metric)

Returns the metric information for the given paint device metric.
