Description skiani 2004-01-02 23:56:32 UTC
Bitmap images are always retangular, eventhough the contents are not
necessarily. So say you have a bitmap which the actual contenting is an
irregular blob in the middle with a green background everywhere else. Now I want
to build a drawing that has just my blob without the background allowing me to
have the bitmap on top of say another bitmap but not show the green background
or the retangular outline of the bitmap object. I could do this in
GIMP/Photoshop but that is a lot of complex steps and only result in a bitmap.
If OOo Draw (ideally the functionality would work with drawings in all
applications) would give me a formating option "Hide Background" (say a right
click on the object and under the format menu). That would pop up a dialog box
that would have a before and after preview of the bitmap (similar to the
"Convert to Polygon" dialog). You could click anywhere on the preview to select
the background color that would set RGB values that would be shown in the dialog
and could be set manually. The dialog would also have a fuzziness factor that
the user would set (0 for exact color match, 1 for + and - one color level, 2
for + and - two color levels, etc.) which the program would clear out colors
that were either exact matches or close. Finally there would be another value on
the dialog for "feathering" this would be how many pixels from the edge of the
object to include (value could be positive or negative).

This has also been an issue for me.  It takes too long to do it with gimp but
that's my only option at the present time.

I believe what is being asked for can done with the Tools -> Eyedropper (I am
running OOo 1.1). Touch the eyedropper to the colour to replace, and have the
replacement colour being "Transparent".

I do have to suggest that it is not at all clear from a user interface
perspective that the Eyedropper would be the method of doing this. Since it's
such a common function, it might make more sense to have a seperate
"Transparency" menu item/dialogue.

Ooops... just realized that I also had white text grouped with my objects that
was also lost in the white background...
Comment 5 skiani 2004-01-08 20:42:54 UTC
Hmm, I have been using OOo Drawing for several years and never noticed that
before. Works pretty well, a bit confusing interface. Still has problem though,
if you export PDF it does not maintain transparency (assuming that PDF supports
that ability). 

I just tested it a it does seem to print properly on a postscript printer. If
you print through a pdf converter (not use the built in pdf exporter) it does
retain transparency) so that is a bug.

To grep the issues easier via "requirements" I put the issues currently lying on
