Description Mark van Rossum 2012-05-25 10:43:14 UTC 
Problem description: 
In  the attached file it is almost impossible to select the bitmap. The only 2 ways is to click exactly on the edge of the image, which is hard to see in this case,
or draw a selection box around it.

Usually I can just click on a bitmap to select it.


(DOes the transparency of the bitmap cause the problem?)

Please don't update version as it is supposed to be the oldest version that the issue exists.
Comment 7 ign_christian 2013-05-27 08:11:47 UTC 
confirmed, same behavior on LO 4.0.3.3 (Win7 32bit) 

Image can be selected with random clik/double click on many parts of the image, then accidentally it selected.
Comment 8 Jorendc 2013-05-27 19:12:52 UTC 
I can reproduce the problem using Linux Mint 15 x64 with LibreOffice 4.0.3.3. You can indeed select the image by dragging a selection box, but once selected you can not right click on it properly.

So marking this as NEW.

Kind regards,
Joren
Comment 9 Mark van Rossum 2013-10-07 12:14:14 UTC 
It appears a problem with the 'bitmap with transparancy' format.

Because after Copy and 'Paste special-> Bitmap' it is ok.

Essentially, yes. If I extract the PNG (/Pictures/1000020100000A3B0000087380C7F4CE.png) from the ODP and open it with Inkscape the behaviour is identical. I have to click on a non-transparent part of the image, which in this case is tedious because of the fine nature of the content. The same behaviour is also evident under v3.3.0.4 and v3.4.6.2 so it presumably has always been this way in LO.

In MS PowerPoint Mac 2011 this transparent PNG (once inserted) is handled in the same manner as any non-transparent image i.e., the image is selectable via the entire area. I am uncertain whether this is a bug or an enhancement request for parity in behaviour with MS PowerPoint. If it is a bug the Version can be set to Inherited from OOo.

Summary edited for clarity.

... I completely agree with and confirm too, but if you make the bitmap clickable (i.e. right click on his few selectable parts -> Interaction... -> Go to Page or Object -> select Slide -> OK) than the whole/entire/full bitmap became clickable in the transparent areas too! ;-)

So we have two different behaviours, each someway correct or with some sense/logic, on selecting/clicking a bitmap...

Only my 2 cents.

Have a nice day,

Carlo
