svg2png

svg2png is a perl script to convert the svg files in the current directory into png images, doing the conversion only if the svg file is newer than its corresponding png.

Usage

Simply run ./svg2png in the working directory.

On 6 January (2024), I had to amend this 2008 script with the line

    print MyMakefile "\tinkscape -h 7200 -b white -o $file.png $file \n\n";

since the export option is not -e anymore but -o. I also added the -b=white option to force white background. This makes version svg2png v°0.2.

Versions:

1. v0°1: 3 November (2008).
