Description Pablo Rodríguez 2005-05-07 07:52:10 UTC

[Already reported at http://bugzilla.gnome.org/show_bug.cgi?id=303363.]

In documents with vector fonts or graphics, evince needs a bit to render them in
a proper way when the window has been resized or the text has been zoomed (in or
out). This is specially noticeable using
http://project.ktug.or.kr/dvipdfmx/sample/omega/gentium.pdf.

Couldn't this behaviour be improved? gpdf renders the chars fine fine when
resizing or zooming.

The performance problem with this PDF is more likely because of the pattern in
the border of the page.  Still needs to be fixed, though.

(This is mostly a cut and paste from a bug I filed against evince, but is more
likely a poppler issue.)

I'm seeing similar problems with this file:

http://www.bv.com.au/file/MTB_ride_You_Yangs.pdf

Steps to reproduce:

1. Open file with evince, move to second page and set magnification at 200%.
2. Close file.
3. Reopen file with evince.

Evince should start reloading the file starting at the second page (it opens of
the second page).

It takes me 2 minutes 10 seconds to see anything (other then the work Loading),
and a blurry preview never loads.

I'm on a 2GHz Pentium M processor.  The system has 1GB memory and the CPU is
running at full speed.  I'm not doing anything else (other than what Gnome
does) at the time of testing.

This seems far too long for anything to appear.

Viewing at 100%, I see the bottom of the 1st page in seconds, and then it
takes about 70 seconds for the second page to appear.  Again, no fuzzy preview
of the page appears

Both documents render fast with current cairo backend.
