Cached image previews while editing

Good idea! Top priority.
Useful, but low priority.
What a waste of time THIS "feature" would be.

Feature suggestion: Cached image previews

Post by DylanMuir » Sat Apr 18, 2009 2:21 pm

I use Mellel to write journal papers (and theses), and need to insert quite a number of images. Some of these are complex PDF files, and take a few seconds for Mellel to render every time they appear on screen. However, their appearance seems to be re-computed every time an incremental scroll is performed! This is a huge waste of time, as one might imagine, and using a two-finger scroll or a scroll wheel becomes basically impossible. I could generate a low-resolution pixel preview while editing, and replace it with the original once done, but a) I don't think I should have to and b) I'm sure I'd forget some of the figures...

I suggest that a pixel preview be computed once for a given zoom level, when the image first appears onscreen, and then be cached by Mellel until the zoom-level changes. Of course, Mellel would print the original image file.
