gsvg: widget to display svg files

In jverzani/gWidgetsWWW2: Toolkit implementation of the gWidgets API for use with web pages

Description

This widget displays an svg file, such as is made by the svg driver or the devSVGTips driver in the RSVGTipsDevice. The basic usage is like gimage, where a file that is stored in a place the web browser can serve is used as the file specified to the device. The convenience method get_tempfile (and function) is used to create such a file. Use the .svg extension. The widget size is specified in pixels, but the svg device driver is in inches.

Usage

gsvg(f, width = 480, height = 400, container = NULL, ...,
  ext.args = NULL)

Arguments

f	filename. Usually produced by get_tempfile(ext=".svg").
width	width of widget in pixels
height	height of widget in pixels
container	parent container
...	passed to add method of parent container
ext.args	Means to pass additional arguments to Ext constructor

Value

An ExtWidget instance
