RE: Changing the Y axis

Hi,

Unfortunately, SVG works from the top, left hand corner. There are two ways
to move the axis back to the bottom left hand.

1/ translate everyting by defining a transformation and using it in all
objects and use y = -y

2/ calculate all the points.

3/ create an svg document and embed it at the position you want using the
$svg->image() method. For this case, you just need to use y=-y.

I use option 2 for the line calculator at
http://roasp.com/svg/lines.html
This is the most reliable and fastest option but the most cumbersome.

Ronan.
