PowerPoint Text Highlight not displaying #126

Open Draern opened 5 years ago

Draern commented 5 years ago

When importing a Powerpoint with "highlighted text", the actual highlight is not showing while the text is displayed correctly.

Steps to reproduce : 1) Add some text on a slide with a colored background 2) Highlight the text in white so you can see it 3) Add the presentation to Quelea 4) No more highlight around the text

(I don't know if the correct term is rendered or else, as I think I've read somewhere that Quelea is doing some sort of conversion of the .pptx.)

Minor Issue and easily avoidable but if there's something you can do to avoid someone else the heart-attack when displaying dark text on a dark background without any contrast highlight.

This is (yet another) limitation of the library we're using to show powerpoint presentation previews - there's unfortunately not really a lot we can do about it short of extensively rewriting that library, which we don't have time to do.

We have mooted around writing our own powerpoint support so we could fix things like this, but it would be a major undertaking that's (unfortunately) unlike to materialise.

Just to add to this; If you use LibreOffice or PowerPoint this will only be true for the thumbnails, not for the actual projection output.

I've actually been thinking about trying to write some code to create thumbnails using PowerPoint if that is installed instead of the library we use, but I haven't had the chance to look at it yet. It should also be possible to do something similar with LibreOffice.
