Megazine Performance
« on: October 23, 2009, 12:13:20 pm »
Hello

I’m trying to use Megazine3 V2 RC2 to display a pdf newspaper. I’m using pdf2swf but the swf generated
must be too heavy because the performance of the page flip is really slow.

I tried creating a the swf using the zoom option with low values but to get a quality performance the zoom must be at a value like 20, this generates a very
small swf. 

I tried using some of the pdf2swf option so that the swf uses less recourses, but despite it improves the performance it is  still too slow.
I tried using some simple PDF and it worked, the performance is good but when I switch to a heavier PDF it slows down.

Can you guys please advise me how to achieve a PDF that uses  few recourses so that the page flip doesn’t depredates the performance.

Thanks for the help

How big is your pdf file?
I e.g. realized that pdf files (same with svg files) created with scribus are unreasonably big!
Doing a quick "rduce file size" under "documents" in Adobe Acrobat (NOT the free reader, the "real" Acrobat) reduced those files by a factor of 8 up to > 30!

Not sure if that is the reason and potential solution for you, but would be interesting to know what file sizes we are talking about.
In that case (too big size) MegaZine3 cannot do anything...

Ok, I found a solution . I modified the pdf2megazine.bat to use this pdf2swf command:

%PDF2SWF% -G -s bitmap -s jpegquality=85 -s zoom=100 -s subpixels=1 -p %%i "%FROM%" "%TO%%%i.swf"

This produces a medium quality swf that is aceptable when viewing the swf with megazine, but it's not
recomended to zoom this content, because of the quality.

Thank you! Not really satisfactory, though.
We'll have a look into that... later ;-)
