Issues with exporting Clipart shapes

[ane-gabriela]

Steps to reproduce:

1. Add some Clipart shapes in a diagram
2. Export it as PDF, HTML, XML

Expected results: The shapes added are exported and shown.

Actual results: The Clipart shapes aren't appearing.

Environment: Windows 10, XWiki 10.11.3 with MySQL 5.7 and Edge 18

Seems like the problem (or at least for HTML) is caused by bad URLs that are generated at export (a combination between draw.io & local instance of xwiki paths).

Now, depending of the use-case, would it be useful to provide a local URL (from local instance of xwiki) or URLs for draw.io hosted cliparts?
WDYT, @mflorea?

@arcilli can you post an example of an HTML export of a simple diagram with just a single clipart shape? (in order to better understand the issue). Thanks.

    <g style="visibility: visible;">

Same problem with broken links is present when exporting diagrams with regular images (i.e. the images that are uploaded as attachments - image src example when exporting https://www.draw.io/xwiki/wiki/sub/download/Diagram/A%20diagram/WebHome/Pim_batman-mask-clipart_273067.png). Considering that, I'm thinking more about providing links from a local instance.

[mflorea]

Indeed, the URL

https://www.draw.io/xwiki/webjars/wiki%3Asub/draw.io/8.9.9/img/lib/clip_art/networking/Bridge_128x128.png

is wrong. We need to find the place where this URL is generated and hook our code that uses the current host instead of draw.io (like we did for the URL export).

I don't know if it's the same cause, but neither JPEG files are exported in PDF (tested with Diagram Pro 1.7.1 on XWiki 11.3.3).

Diagram from XWiki page:

Diagram exported as PDF:

Environment: Windows 10 Pro 64 bit, Chrome 76, using a local instance XWiki 11.3.3 on PostgreSQL 11

@ilieandriuta is probably referring tot the PDF export from the Diagram menu, not the XWiki page export.

[ilieandriuta]

Yes, I was referring to JPEG files not being exported to PDF export from Diagram, basically following the Steps to reproduce listed above on this issue.

[arcilli]

@ilieandriuta, seems like that issue is already presented in #61.

[ane-gabriela]

Export as HTML was removed - see #53
