Hi,

A little project I was doing is taking much longer than I thought, so I thought I would post here and see if anybody could point any way forward.

I want to take an SVG file and produce it at various magnifcations in PNG form. I'm using Image::LibRSVG for this batch file writing procedure, which is probably not what it was built for. 
#!/usr/bin/perl -w
use strict;
use Image::LibRSVG;

my $rsvg = new Image::LibRSVG();
my $infile=$ARGV[0];

for (my $i=1;$i<=10;$i++) {
    my $fs=sprintf("%05d.png",$i); 
    $rsvg->convertAtZoom($infile,$fs,$i/10,$i/10); # be careful 1, is 
+normal zoom, not 100!!!
    undef $fs;
}

undef $rsvg;

What I would like is to not have the loop reading from file each time .. so I was thinking about referencing it as a filehandle and then dereferencing. A go or no-go area?

Idea is to make the code faster.

A bigger problem is that the output file is a different size each time. So I want to create a set canvas size and map the zoomed output to it. This can be done with GD, but again, Image::LibRSVG insists on saving to file each time. In fact it only has one saveAs method, and that's to write to file. Any ideas for me?

Image::LibRSVG is starting feels more like a wrapper, may be I should be looking into cairo for this.

Thanks for any ideas in advance. Cheers.
