Description jonas 2004-10-17 13:36:17 UTC

Version:           0.20 (using KDE KDE 3.2.3)
Installed from:    Mandrake RPMs
OS:                Linux

It seems to me that KGhostview is painfully slow compared to e.g. gv and xpdf. Every time I try to read a new page, it takes several seconds for the page to render. This pretty much makes KGhostview useless for on-screen reading. Disabling anti-aliasing helps a bit in performance, but makes the text unreadable.

This is only the case for certain PDF documents. Some I have that take a long time to render where created with Adobe 6 tools and contain many images, stuff I create with Latex usually is rather quick. Here is an example that takes long: http://www.sts.tu-harburg.de/teaching/ws-04.05/ltooad/slides/08 - oo libraries and extensions.pdf. this file is very slow, it was created using Adobe 6
Here is one that is rather quick: http://www.sts.tu-harburg.de/~se.bossung/pdf/bossung03-schema_mapping.pdf even pages with many more bitmaps than in the first PDF (like page 39) render in under 5 seconds. This file was created using dvips and ps2pdf.

Could you try Okular? The performance should be quite better.

No answer for years.
