1. Let's have an svg A nested into another svg file B.svg

2. Convert B into another format - let's say png- using Imagick

3. A positioning is not correct, and it's close to the upper left side of the main svg.

4. As you increase the size of the main svg, its position after conversion is moved in the upper left side, more and more, until it's not processed and not shown in the converted file B.png


I have another server, (Debian 7 and Imagick 3.1.0RC1, Version: ImageMagick 6.7.7-10 2014-03-08 Q16), and it works like a sharm.

It follows an example of a wrong rendered SVG:

<?xml version="1.0" encoding="iso-8859-1" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//Dtd SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/Dtd/svg11.dtd">
<svg width="200px" height="100px" id="MAIN_SVG" version="1.1" xmlns="http://www.w3.org/2000/svg">


 <rect x='0px' y='0px' width='100px' height='100px' fill='black'/>

                                <svg transform=""  x="100px" y="0px" id="NESTED_SVG" height="100px" width="100px">

                                        <desc>    Imagemagick doesn't render this embedded (nested) SVG   </desc>

                                        <rect x='0px' y='0px' width='100px' height='100px' fill='red' />


                                </svg>

</svg>

I expect the svg with tag "NESTED_SVG" (a red square) should be positioned 100px from the left.

This is the result in my old server mentioned above (debian 7). In a brief on the old server it works.

On the other side with this server and the enviroment explained at the beginning of this report, the "NESTED_SVG" is positioned at -25px, i.e. the WRONG position.
