I use Inkscape as a UI designer. I want to export each group as a single SVG using the python parser and Inkscape command line renderer but I have problems with the coordinates of each object.

For example I have a group which is a complete window. Inside this group we have another group (for example the close button) that includes a path, a rectangle and an ellipse.

And the parser create tree of folders depending on <g></g>. When the parser "sees" the <g></g> then it creates a folder named <group ID> and goes deeper until it encounters <g root_img="true"></g>. Everything between <g....></g> is treated as separate SVG and calls Inkscape command line to render it, and save it as *<group ID>*.png.

This is what I have.


I want the coordidnates values, for instance:

close_btn 1250, 10
title_bar 0, 0
product_belt1.png 150, 150

But how do I get the absolute coordinates of each group?

EDIT: It is possible to make a plug-in which I add additional arguments[x=150, y=120] to all groups in XML?

Not solution but part of it, idea

1 way «semi-automatic» Place tranparent 1px rectangle with mark-color #f1f2f300 in left-top corner of group and get coordinates of mark-object by parser.

2 way «automatic» As I understand it needs absolute coordinate from top-left corner, such as the size of document 1000x1000 pixels document, the root-group (height=100px) at the bottom left corner, then she has the coordinates x = 0 and y = 900. Root-group have subgroup and she has same coordinates. Or need a subgroup relative coordinates? Example root-group(0,900) subgroup (0x0)?

If you need only the absolute coordinates here easier — parse group. Compares the coordinates of objects within a group, we need an object with the smallest (x,y) coordinates. This is the position of the group.

But a little more complicated when inkscape added parameter like transform="translate(0,-100)". It appears when the group made a duplicate and change the position of the group. Here it is necessary to make additions and complicate the logic.


I did something very similar a few years ago. After exploring many different options for parsing SVG files I ended up with using html/javascript. Back then I traversed the SVG file using jQuery but I'm sure there are better libraries available today (and it could be a good idea to use a headless browser).

Once you know which element you want you can call Element.getBoundingClientRect() to get the absolute coordinates of it.
