Hello,
I'm again testing the LyX 1.4.x branch and found another annoying bug.
When the Graphics dialog is opened to modify the properties of a
graphic, and no information has previously been entered on the Clipping
tab, LyX activates the "Get from File" function and grabs the bounding
box information from the current graphic file. This is probably done to
make it easier to customize these values. If you don't modify them,
nothing will change.
That's all a good thing. It goes wrong when LyX is unable to get the
bounding box from a file. This happens for example with all MATLAB
generated EPS files (see below). This time the values on the Clipping
tab are cleared (they become empty, not zero).
I don't really mind that these values are not filled in, but the problem
is that you cannot press the OK button anymore, because it's detected
that the bounding box text boxes contain invalid values (the labels
become red), even though I did not modify anything and never clicked the
Clipping tab.
Because the problem is totally invisible, it took me a lot of time to
find out that this was actually the thing going wrong and to figure out
why I could not press the OK button.
To fix this, LyX should set the bounding box values to 0 when unable to
get them from the file, instead of making the text box empty. Or
maybe only check for valid values whenever the user modified a value
(otherwise the value is not going to be saved anyway and there is no
point to check it).
The actual reason why the bounding box value cannot be read is that it
contains spaces:
%%BoundingBox: 87 262 507 578
That should probably be fixed as well. Both look like very obvious
things that are easy to fix. The bug however is quite a big one when
working with MATLAB images. You keep removing and inserting graphics if
the OK button doesn't work :)
