Description john_257 2005-03-22 07:31:49 UTC 
Hi,

I'm using OpenOffice Beta 2.0 build 1.9.84 on Windows XP.  If I create a drawing
in Draw that uses filled areas what are transparent, when I export to an EPS
file, the transparency of the filled area is lost.  Whatever is behind the
transparently filled object is completely hidden.  I will attach a small draw
file that has the problem (just export to EPS).  

Thanks,
John

EPS is not supporting transparent bitmaps. To keep the transparency in the
created eps file it would be necessary to export everything in a single bitmap,
but this is not easy for encapsulated postscript files, because eps normally
does not have a fixed target resolution. Furthermore the filesize would grow up
enormous if switching from a vector graphic to a bitmap graphic.

sj->thb: do you have an idea ?

Retargeted, due to resource constraints.

If the figure is exported to PDF, converted to PS (using pdf2ps) and then
converted to EPS (using ps2eps), the transparency is preserved.

@jmfv: sure, but it's a high-res bitmap, if you look closely.

@sj: please take this one back.

Hello,

I think the goal is not to keep the transparency in the exported eps, but to
flatten the transparency, so that the eps looks like what was on the OO screen.

Can this be done without bitmap ?
