"Textbox" shape isn't showing in XWiki PDF export #100

Closed ane-gabriela closed 4 years ago

ane-gabriela commented 4 years ago

Steps to reproduce:

  1. Create a new Diagram
  2. Add the Textbox shape (with Heading)
  3. Click Save & View
  4. Access More actions > Export > Export as PDF
  5. Deselect all options > Export

Expected results: The shape / text is shown properly.

Actual results: "[Not supported by viewer]" appears instead of the shape / text.

Environment: XWiki 8.4.5 with Chrome 78 and Diagram Application (Pro) 1.12

We need to debug the createAlternateContent function. Currently the expected behavior is to view the HTML inner text in PDF export (as a fallback for the SVG foreign object which is not supported by Apache FOP).

The fix is just a first version of how inserted text is seen in xwiki pdf export. The resulted pdf will not be 100% accurate (e.g. the alignment will be center, regardless of what was set)

An example of differences that can be seen:

Created diagram: created_diagram Exported diagram exported_diagram

Besides the rendering of basic text shapes (simple short text, headers) this fix also manages lists (without their corresponding numbers or bullets)
