capabilites: Query the supported input formats for grConvert

In sjp/grConvert: Converting Vector Graphics

Description

In order to read in an image, grConvert requires that an associated renderer is available for use. This is determined when grConvert is installed and by default it will attempt to be able to read in all vector image formats. This function shows how many vector images formats can actually be read in by grConvert so that it may be converted to either PostScript or SVG.

Usage

grConvert.capabilities(print = TRUE)

Arguments

print

If TRUE, prints out the supported input formats for the convertPicture function.

Value

A list keyed by input formats (PS, PDF and SVG), whose associated values are TRUE if grConvert can read in the format, or FALSE if not.

This list is always returned, but it is returned invisibly when print is FALSE.
