test document

Problem description: 

When you open a .doc-file with a formula you are looking at some kind of cached image of the formula but not at how it looks in LO.

So I never can be sure that a formula is imported correctly until I double-click it and enter "Edit-mode".

When I try to edit an imported formula it can change very much.

Steps to reproduce:
1. Open an attached document
2. See that a formula object is displayed "strangely"
3. Double click it and see that it changed a lot!

Current behavior:

Some cached images are displayed instead of actual formula.

Expected behavior:

I need to see how it (formula) looks from the start.

this report is only about initial look of all imported formulas, not about one incorrect formula.
Operating System: Windows 7
Version: release

I should add that the problem exists also for ".odt" files that were generated by saving a ".doc" file.

In AOO, this formula is displayed correctly from start. Although it displays cached image, too, and this is fortunate, because AOO imports this formula broken as well. So, I suppose, it is best to just fix incorrect stretch of cached image, instead of forcing Math component to draw its imported formulas. This way, even if a formula is imported sub-optimally, it will be rendered correctly, which is good if you only want to view/print document contents, or don't need to modify this formula.

(In reply to comment #5)
Submitted Bug 66525.

I agree with comment #6 about how this should be:

"it is best to just fix incorrect stretch of cached image, instead of forcing Math component to draw its imported formulas"

Just need images to be shown correctly. Incorrect import will be another bug.

Attached DOC looks worse in 6.2+. 
I set Bug 61253 as general minor issue: "Incorrect initial representation of formulas in doc files due to incorrect stretch of cached image" because it's exactly about that, and I change this bug to fileopen formula issue with attachment 81816 [details].
