convert: Converting between graphical formats

In TraMineRextras: TraMineR Extension

Converting between graphical formats

Description

Wrapper function for converting graphics with ImageMagick

Usage

convert.g(path = NULL, fileroot= "*", from = "pdf",
    to = "png", create.path = TRUE, options = NULL)

Arguments

path	String: Path to the from graphic files. If NULL (default), the current path is used.
fileroot	String: Graphic root name; default is "*" for all files with the from extension.
from	String: File type extension specifying the from format.
to	String: File type extension specifying the to format.
create.path	Logical: Should the output files be placed in a to subfolder.
options	Additional options to be passed to the ImageMagick mogrify function

Details

Conversion is done through a call to ImageMagick mogrify function. This means that ImageMagick should be installed on your system. It must also be listed in the path.

For values such as "pdf" and "eps" of the from or to arguments ImageMagick works in conjunction with Gostscript. The latter should, therefore, also be accessible.

ImageMagick is not suited for vector to vector format conversion because it rasterizes the image before the conversion. Therefore, convert.g is not suited too for such conversions.

## into .png files and put the files in a "png" subfolder.

## Same, but convert to .jpg files.
convert.g(path="figSW", to="jpg")

## convert file "example.jpg" in current path to ".pdf"
## and put it in same folder.
