Customizing the thumbnails

[fhgd]

• In the actual version the thumbnails show the whole slide (audience slide and note slide). I think it would be more useful to show only the audience slide
• Would it be possible so switch on and off the last, actual and next slide separately?
• Is it possible to move the thumbnails onto the right side of the presenter screen? Maybe the actual slide thumbnail on the upper right and the next one on the lower right?

Thank you for your suggestions, they are good ideas.

These will require source changes, but two of them they may be quite small. If you compile from source, you can try to "make it work" right now using a few quick hacks.

1. Change thumbnail page part:
   • Right now that requires a source change in two functions: toThumbnailRenderIdent and renderedPageIncoming, simply change them to PagePart::RightHalf or LeftHalf depending on your needs.
2. Which thumbnails get rendered:
   • You can try to simply remove or comment out the parts in addThumbnail that set the image to the previous / current / next slide
3. Move to the right of the screen
   • That would be non-trivial right now, since the code is currently assuming that the three thumbnails are (left-right) next to each other, but I'll keep it in mind when I do #60, since displays seem to grow horizontally these days. (I remember 4:3 (~1.33) and 5:4 (1.25) aspect ratios being normal for PCs, these days 16:9 (~1.78) or even 21:9 (~2.33) are commonplace...)
   • That being said, feel free to play around with pdfviewerwindow.ui - use qt designer to edit - and getPreviewImageSize - and please send a pull request if you find a nice layout : )
