I have done some tests about inserting image with the higher width possible, and I can't insert image that would take all the width available in a section.
For the exemple I made a toolspane on the right of the document(check screenshot below)
, working on a A4 format section with no specific paragraph style.
For a A4 format, width is 595.30px, I shortened the margins left and right at 10px, so the max acceptable width for an image would be 575.30px
But as you can see below, all the images width can't reach the right side of the document.
The Editor function "fitImageToPage" seems ok, not the render process .
any idea ?
Thank's in advance.
