The package qtsvg
contains bindings for classes defined by the Qt module
QtSvg.
Besides the capabilites reported below, all qt variants inherit a set of default methods, and all qt object classes inherit the capabilities from their superclasses and automatically expose properties, slots and signals.
You can also use the function
qtwidget.newpdf,
defined in module qtwidget,
to easily generate SVG files.
Returns a Qt object of
class qt.QSvgRenderer
representing the SVG file filename.
Draws a SVG image.
Argument port must be a
qt.QtLuaPainter or a
qtwidget'' high level port descriptor.
Argument svg can be the SVG filename or
an instance of class qt.QSvgRenderer
such as those returned by function qtsvg.loadsvg.
The remaining arguments are the same
as those for the C++ function QSvgRenderer::render.
Class QSvgWidget provides a widget that is used to display the contents of Scalable Vector Graphics (SVG) files.
Expression qt.QSvgWidget(parent) returns a
new widget for rendering SVG data.
The optional argument filename specifies the name
of a file containing the SVG data. Without this argument,
you must use slot qsvgwidget:load() to load SVG data.
The optional argument parent specifies the widget parent.
New widgets are always created from the main thread using
the thread hopping mechanism.
When argument parent is nil or not specified,
the new widget is owned by the Lua interpreter
and is automatically destroyed when the garbage collector
determines that it is no longer referenced.
Returns the qt.QSvgRenderer object associated with this widget.
Class QSvgRenderer is used to draw the contents of SVG files onto paint devices. You should use instead function qtsvg.paintsvg to easily display SVG data.
Creates a new instance of class QSvgRenderer.
The optional argument filename specifies the name
of a file containing the SVG data. Without this argument,
you must use slot qsvgwidget:load() to load SVG data.
The optional argument parent specifies the widget parent.
When argument parent is nil or not specified,
the new widget is owned by the Lua interpreter
and is automatically destroyed when the garbage collector
determines that it is no longer referenced.
This is a thin wrapper around the Qt class QSvgGenerator.
You should use instead function qtwidget.newpdf to easily generate SVG files.
Creates a new instance of class QtLuaSvgGenerator.
When argument filename is present, the SVG data is written
into the specified file. Otherwise it is written into a memory
buffer accessible using the method
qsvggenerator:data().
The optional argument parent specifies the widget parent.
When argument parent is nil or not specified,
the new widget is owned by the Lua interpreter
and is automatically destroyed when the garbage collector
determines that it is no longer referenced.
Assuming the qtluasvggenerator was created without the filename argument,
this function returns a qt.QByteArray
containing the generated SVG data. This data may be incomplete
until painter:close() has
been closed on all painters operating on qtluasvggenerator.
Starting with Qt-4.5, this string property defines
the contents of the <desc> tag of the SVG file.
Starting with Qt-4.5, this string property defines
the contents of the <title> tag of the SVG file.
This property contains a qt.QSize
variant containing the size of the drawable area.
This information is shown in the viewBox attribute of the <svg> tag.
This integer property defines the resolution, in dots per inch,
of the coordinate system.
Together with qtluasvggenerator.size, this property determines
the contents of the width and height attributes of the <svg> tag.
