Memory Managment And Pdf Files?

[Jon_J]

I have a PDF road map of the state of Illinois. (584kb)
Note: this map zooms all the way out to where the entire state fits onscreen, and zooms down to secondary highways. (small state routes). With no loss in image quality.
(Picsel browser does this, I don't try zooming much in the other 2 programs because of the load times)
I've opened it in 3 different programs, 2 on my palm & 1 on my C3100

My Palm has only 2.2mb of dynamic heap memory. Total user/program memory is 24mb.
PalmPDF opens this file, but it takes about 3 minutes.
Picsel browser opens it at the best speed (8 seconds), and zooming is also very fast.

My C3100 has 25702 kb Free (I'm not sure if the other memory numbers come into play here) I try to open this file in "qpdf2_freetype-2", and it takes at least 2 minutes, but the "Map" never appears. The screen is blank.

What do I need to do to manage my memory more efficiently?

My C3100 has almost 22MB free, why can't it open a 584kb PDF file??

Thank you for reading this,
Jon

qpdf2 has worked poorly on most documents I've tried to read.  I think ithe program is just not mature or efficient enough to handle anything beyond very simple text PDFs well.

You could try xpdf instead.  It probably would work under X/qt, Debian, or pdaXrom.

I uninstalled Qpdf2.
I think I'll order Picsel browser for Zaurus and see if I can get it to run from a 1GB SD card instead of the 256MB card it comes on.
