I recently encountered an export issue with a gate-fold card project I created.
The document is a 4 page, "facing pages" project, with mixed spread dimensions:
Page 1: 15x7in
Page 2 & 3: 5x7in
Page 4: 10x7in
It is configure this way so that I get 4 images when I export All Pages, and the single image on pages 2 & 3 is split in half.
When I export All Spreads, it produces 3 images, all with correct dimensions (4500x2100, 3000x2100, 3000x2100).
When I export All Pages, all 4 images are forced into a single dimension (4500x2100).
In all cases, I am exporting using preset JPEG (Best Quality)
I tried playing around with various settings, but always with the same result.
A document is attached from which I can reproduce this issue.
I reproduced this with versions 1.7.2 and 1.7.3 - at first I thought it was a regression introduced in 1.7.3, but reproduced after rolling back to 1.7.2.
