I think that there may be a misunderstanding in the scope of the bug. I believe
this issue is not about slides (that is was not opened thinking of impress),
but about drawings (opened thinking of draw). If you check the very first
message it says "It is impossible to export a selection of a *drawing* to PDF"
and then "Create a *drawing*, not a *slide*. For sure I got here because an
issue opened by myself was marked as a duplicate of the present issue, and my
initial bug was about draw.

While draw and impress are in many senses similar and possibly sharing a large
amount of code, the use cases are quite different.

Indeed it is not unreasonable to have the desire to export a slide including
only some elements and not others and for the slide case it may make sense to
deliver the whole page in its original size (particularly if the slide includes
master objects that span the whole slide).  However, for draw the situation is
more complex.

Draw is often used to prepare illustrations in PDF format to be used in other
applications (think LaTeX or desktop publishing). For these cases you want just
the drawing with a tight bounding box in the final PDF. Because draw does not
have a page format button to automatically restrict the page size to the actual
drawing and because exporting the selection is anyway required for this task
because currently it is the only way to create a PDF without a solid
background, in draw it would seem much more logical to provide a tight bounding
box with the PDF export of the current selection.

A case more similar to the impress one being mentioned would only occur in the
much less frequent case where you have a drawing with a layer including a title
block and margin borders. In this case you may be interested in exporting only
a part of the drawing maintaining the original page format (size + title block
layer).

Please reopen.
