SVG Text Anchor position for Inkscape PDF-TeX export

[dshemnv]

Hi !

I really appreciate this project as it is way simpler to customize the appearance of the diagrams. However, I noticed that on the exported SVG files, the anchor for text boxes is positioned in the middle. This is a problem since when converting the SVG to a PDF file with LaTeX text using Inkscape, the obtained text is positioned higher than it should be.

Here is an example of what I mean:

Produced LaTeX PDF with Inkscape export

It would be awesome if the text anchor was by default as it is in Inkscape, enabling fast integration of the diagrams in LaTeX documents.

Seems like the property that is in charge of this is: dominant-baseline="middle"

Here is the SVG code for the example SVG file used above

Thank you for the issue.

This dominant-baseline="middle" is very probably indeed the offender here. In this case the fix would be rather easy. We already have the pixel height of the text. Just replace the dominant-baseline=middle with a offset on the y coordinate.

I will see what I can do to fix this.
