SVG as it should be vs as shown by LibreOffice

Inserting SVG images in documents is not displayed correctly:

SCENARIO:
Open a blank document,
Insert a svg by dragging or any other method.

How it should behave:
- Display the SVG image as per the SVG standard

How it is displayed:
- The svg image is something similar to what it should be, but nothing exact or correct.

SVG is one of the most important format, used for logos, diagrams, etc..

IMHO, it is the third most important feature after writing and saving the document.

Confirmed with v4.4.6.1 under windows 7 x64.
It affects multiple components, not just writer. Strangely enough when using writer there's a border around the image, which doesn't happen in calc/draw/impress.
Comment 4 V Stuart Foote 2015-10-17 23:19:51 UTC 
Both insert and open filtering mishandles the simple Inkscape derived SVG. No improvement if the SVG is changed to SVG plain rather than Inkscape native.
Comment 5 Regina Henschel 2015-10-27 18:30:24 UTC 
svg-filters are not yet implemented. That is a missing feature.

> svg-filters are not yet implemented
It is not only a mater of the shadow, it seem like converted to a low polygonal shape.
I could leave without filters and/or convert shadow into gradients. But the low fidelity of the rendering is a block for decent documents.

in LO 5.2.0.0.alpha0+ (x64) the curves are smooth, even with max zoom level

The fix could also be available in latest 5.0 or 5.1 tree

Comment 13 Xisco Faulí 2023-06-26 21:17:33 UTC 
feOffSet is not the only reason why the svg is not displayed correctly, there are other filters not supported as well
