I thought PgS could handle pngs, though I could be mistaken. The pngs I've
tried to load always load with a translucent fill where it should be
transparent. One file is a light blue, the other a red. In both cases 50% or
more transparency I would guess.

Was I mistaken about the transparency and pngs? BTW: same problem in 5.0.3.3.

I have always had png glitches with PGS, i.e croppping, but not on printouts,
transparent areas printing (but not on display)...I workaround wth jpegs

How do you work around transparency issues with jpg? To my knowledge PgS
doesn't support any transparency in jpgs even if the standard does (the
original certainly didn't though jpg 2000 might)

Also, are you saying the images would have printed correctly?

As to the cropping issue: I don't crop images that often but the only cropping
issue I recall is with PgS's PDF export. Are you seeing cropping issues with
printing then?

It seems to work here. I'm just now migrating to a new mail server, but
if you can email me a sample I'll test it here.

Thunderbird, honest...)

True, JPEG does not handle transparency, (so far as I know), but let me
explain the PNG problem I ran into.

1. Here is what happened. When needing irregular shaped pictures, I cut out
using GIMP, and then pasted into new picture with transparent background.

I saved as PNG.

2. I inserted into PGS, and on screen, all looked well.

3. When PRINTING, the transparent section (that I thought had been cropped in
GIMP, and didn't show on screen in GIMP or PGS) all of sudden is printed!

Really bizarre to me...

4. So then I saved out the 'GIMP' cropped images as JPEG, (white background),
and in PGS, sent them to back (using stack) behind the text they needed to be
close to, since the 'white block' surrounding the JPEG would have masked the
text block.

> As to the cropping issue:

Yes, printing has a problem also with cropped images (at least PNG).

Thanks, I certainly can. I'll make sure I can replicate it with a smaller
image as you probably don't want the one I'm using for print ;^)

Okay, I understand now. Unfortunately for me that is no help: the problem I
have is overlaying a bitmap against a background that needs to show through.
Normally I could just mask the graphic, but in this case there are holes that
need to be transparent.

I was just finishing off the email to you when I discovered the crux of the
problem. I'll go ahead and send the image for testing/fixing of the issue,
but to make sure this thread shows what is going on:

This works if the PNG is in color mode. I was using a greyscale because that
is what the image is. There's some more detail to it, but basically it worked
for me when I changed the image mode to color.

And make that partially work: it prints with black for the transparency. Sigh.

hi,

after moving to a different server, bugzilla.pagestream.org is up and
running again. I've just added version number 5.0.3.4. maybe someone
could check if everything's fine again (especially mail notification) by
entering new bug reports

cheers
