Hi group, I am considering building a photo album application. Can anyone give me advice on what Image APIs may be used. Are there any specific APIs for different devices (Palm, Sony, ..., OS5) or a standard can be used. What APIs are used for building the image databases (storing images) and what APIs are used for rendering images on devices. What formats are available. Is there any common image format (say .bmp) that can be used for both Palm and PocketPC devices. Thanks!

Re: Distributor greed - Are there other distributors
I agree with your complaint, but I disagree with your math. The Feds are also taking 28% from Handango, so the math should be as follows; Feds 28% Handango 28.8% Developer 43.2% I have been using www.ShareIt.com as my storefront. They only charge a max of 14.9%, and they have a very advanced interface, and good service. But since they are not as Palm oriented, you have to do all the getting out the word.

Distributor greed - Are there other distributors
Sorry for posting this in this forum. I don't see any other fourms that I'm subscribed to that are more appropriate. Just received another increase notice from Handango. Are there any other better ( or as good ) distributors than Handango or PalmGear? My reply to Handango's email: You are taking far too much, for such little return. You are taking 40% and the feds are talking 28%. That leaves only 32% for the people that have put in all the "real" work. Greed is at work at Handango.

Shim stops pining after 20 minutes
Hello and thanks in advance for any advance that is given. What I have is an arm 'shim', somewhat like the sample 'VPPI" that one can download from Palm One. In this sample there is a shim that basically can trap the packets as they are coming and going from the hardware, nic. Basically my shim/vpn, is working fine but when I do some long testing, that is I am pining my Tungsten C continuously from another source I have seen that the Tungsten stops replying after about 20 minutes. Has anyone seen this behavior before? Any suggestions as to how to keep my 'connection' alive. The shim is just an interface, like 'WiFi', so it should run on the same process, but if I just open the 'WiFi' interface, I notice that my pings, going to the tungsten, with out my shim loaded, will go with out stopping, at least past the 20 minute mark. Looking forward to you replies. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Displaying unicode
I have run into a situation where I need to display unicode characters not in the 1252 code page. From what I've been reading, it would appear that I need to make my own custom font to do this. Is that correct? Are there any commercial fonts folks can recommend that are made for this kind of problem, or does everyone just roll their own?

Re: Indexing algorithm for index file for a dictionary
Thanks Matt and Ken for your suggestion. Well, if I store one word (or phrase) per record and let the database sort for each insertion or deletion action, that would cause a huge processing overhead and I doubt a user would like to wait that long. So, I am thinking of storing several words per record and then using a binary heap for indexing purpose. This way, in case of insertion, I would be able to add the word anywhere and all I need to change/refresh is the index database (which is a binary heap containing pointer to dictionary database records) - no resorting of dictionary database.

First, I'm not a C programmer: at best I'm a C hack. Regardless, I decided to try PODS as a first environment. Luckily I've worked with another Eclipse-based IDE so that helps a bit, but the basics of Palm programming are not revealing themselves. Seems like you are doing this the hard way. Perhaps you'd be better of licensing a copy of the Metrowerks Codewarrior 9.x compiler for Palm OS and using the standard Palm SDK. Remember that the primary focus of PODS is an early release of development software for a future version of Palm OS. While it can be used for current versions of Palm OS, there are more stable solutions available to you, unless your objective to develop applications targeted at this future version of Palm OS.

Image APIs?
Hi group, I am considering building a photo album application. Can anyone give me advice on what Image APIs may be used. Are there any specific APIs for different devices (Palm, Sony, ..., OS5) or a standard can be used. What APIs are used for building the image databases (storing images) and what APIs are used for rendering images on devices. What formats are available. Is there any common image format (say .bmp) that can be used for both Palm and PocketPC devices. Thanks!
