SVG exported incorrectly in output DOCX and PDF using .NET

Aspose.Words Product Family
#1

Hi

We have some troubles with the correct layout of svg images in word or pdf. Also there are different behaviors saving either as docx or pdf.

Problems:

  • Text alignement ignoring text-anchor: end / middle (occurs when only transform="…" without x=“0” y=“0” is set)
  • Arc drawing: incorrect output in pdf
  • Font-Styles: incorrect output in word (when fonts are not installed locally)
  • font-weight seems to ignore numerical values as 400,700 (workaround use normal/bold)

Windows Universal, Aspose.Words v18.10.0

Could you please give us some hints for possible solutions/workarounds.
Thanks in advance.

Annotation:
WORDSNET-17629 The problem of my provided example is not the position of the vertical lines, rather than the Text alignment, if no coordinates are given:

If the coordinates x=“0” y=“0” attributes in the svg text tag are missing (only the transform attribute is provided, assuming implicitly x/y = 0) the text alignment is not applied correctly.

svg Code, not aligned centered in pdf/word output:

<text class="light medium" transform="matrix(1,0,0,1,120,50)">Medium</text>
<style type="text/css">
   .medium {font-size:22px;text-anchor:middle;}
   .light {font-family:'Lato Light';font-weight:'normal';}
</style>

svg code, works fine (added x=“0” y=“0”):

<text class="light medium" x="0" y="0" transform="matrix(1,0,0,1,120,50)">Medium</text>
<style type="text/css">
   .medium {font-size:22px;text-anchor:middle;}
   .light {font-family:'Lato Light';font-weight:'normal';}
</style>
