Vertically.

Again, I'm scanning css files and extracting background url().
Once I have the path to the image I can use Ping to determine the
height of the image. That's really all I need.
The images are of different sizes, but they are all aligned on the
left edge of the resulting image.
So, say I add the first image of 10x10. It's accessed in css
by 0px 0px (upper left corner).
Then next image is added and it's size is 20x20. The "canvas" of the
image expands (with transparent background). It's css position is 0px
-10px (from previous image size).
Third image will be at 0px -30px.

Well, I'm using PerlMagick, but not sure of the best approach.
This seems close, though:
$im = Image::Magick->new;
$im->Read( @list_of_image_paths );
$montage = $im->Montage(
mode => 'Concatenate',
tile => '1x',
background => 'none',
);
$m->Write( 'sprite.png' );
Is .png the best format to use? Writing to .gif in my simple tests
results in a smaller image.
Sorry, my knowledge of this is limited. So, any pointers or
suggestions would be very welcome.
