there is also pnojpeglib - but as far as i know it needs arm device and won't run on m68k at all. so in worst case you can do support for both (its not so difficult)
but it won't save you some tweaking, because pnojpeglib by default doesn't support decoding of image line by line, its done internally so maybe it would be possible for you to add extra api for that (sources are available). i never played with it myself so i can't guess how much work would it be....take it only as hint (usually its less work to change existing sources then create new one and porting jdpalm to arm code seems like a much more work to me) Marcin wrote: > Hello, > I wrote here about mount ago, to ask if there is a good library for jpeg > decompression which could satisfy some conditions: > -run under PalmOs 3.5 and higher > -allow to decompress jpeg file line by line (no need to store whole file in > memory) > > So, conclusion was to use "jdpalm" library. > I must admit, that it's a great lib, but now i have to make the > decompression much faster. > > My question is : is there a jpeg decompression library for ARM processors > allowing me decompress file "on the fly" (like jdpalm do) > > If no (but i hope there is), i think i will have to rewrite jdpalm from 68k > to PNO, bu i have no idea how to do this (i have a lot of time, and willing > to learn if it's necessary :) > -so any links to to documents/tutorials/guidelines how i can do it would be > helpful > -also some hints what do i need to have/learn > > Thank you > Marcin > > > -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
