Re: Any sample for PalmPhoto APIs ?
I'm still looking ito exactly what they mean by all of this :-)
...it's not the most clearly worded of statements, especially as the
libraries themselves are not actually mentioned in the doumentation at
all...
... I have access to both pieces of hardware and will report !
...but right now I havea bit of a problem. If anyone can help with this
one...
I'm trying to use the libs to display a (roughly) 320x320 jpeg on a 16
bit display. Here is the function I'm using:
The symptom is that the colors look like the palette is messed up. The
screen is set up in 16 bit mode as well.
Anybody see anything I'm missing?

Umm, the SDK comes with an installable version of the PalmPhotoLib.prc ...
The readme.txt file in the PalmPhotoLib of the SDK says:
QUOTE
The Palm Photo API allows developers to take advantage of services in the
Palm Photos application, v.1.1.0.20. The API will work only in conjunction
with Photos v.1.1.0.20 which is available on the Tungsten|T3 and Tungsten|E
devices.
/QUOTE
Anyway, I want some thing that won't need an external prc. So I will stick
to jcpalm which can be included directly into my app.

I did not look in detail into your code but just in case you don't know, here are a few hints: - Palm use RGB565 for it's 16 bit color. Most JPEG library convert to 24 bits RGB. If this is your case, tou must convert your data from 24 bits RGB to RGB565. It is done by masking and shifting. 5bits for R, 6 bits for G and 5 bits for B. The library I am using (jcpalm) can convert directly to RGB565. It is avaliable from the eyemodule web site in the developer section. www.eyemodule.com It can be used freely as long as you acknowledge the copyright inside your own copyright. It is the case for all library made from the code from the IJG (Independant JPEG Group). See the readme.txt with the library. (By the way, if you open the about box of MSN Messenger, you will see the same acknoledgment of the IJG) Hope this helps -- Regis St-Gelais www.laubrass.com -- -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Hmm, I guess I assumed the Palm Library would know enough to do this on it's own. I'm going to look at the FotoFinish source again to see how they handle it, they may do the conversion with the callback, hold on... ... hmm, interesting. I think I might have a clue what is going on now. It looks like some assumptions are occuring in the library about the layout of the bits in the window, experiment in progress... Okay, I have it figured out. You have to create the window in native format. If you don't the bytes get swapped into the wrong order and the display is messed up. I was creating the bitmap, then creating a window from that, turns out you need to create an offscreen window and go from there. Who knew?

Not is source form, but in compiled form as I'm using Codewarrior 8 and the source is for 9 (I think the object format is compatible...) Chris PS.

As I said, you can download it (source and binary) from http://www.eyemodule.com/developer/index.asp It is labeled : palmOS® JPEG compression library Just click and you'll get it. It can be used as a shared library prc or you can include the source in your code. There are samples with the lib to do both in CW. If you recompile it, you will need to make a small change in the source code (bug on newer version of codewarrior that will be corrected in the 9.3 patch) See the thread Build jcpalm library with cw9.2 started in January 26, 2004 Best regards. -- Regis St-Gelais www.laubrass.com -- -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

But I am having a hard time making the palm photo APIs work.
Well, I am not even able to load the library.
err=SysLibFind(PalmPhotoLibName, PhotoRefNum);
if (err != errNone)
{
err=SysLibLoad(PalmPhotoLibTypeID, PalmPhotoLibCreatorID, PhotoRefNum);
}
Those 2 calls both give me a lib not fund error.
I a debuging directly on a Zire71 device.
There's a readme.txt in the Extra\PalmPhotoLib directory that says:
The Palm Photo API allows developers to take advantage of services in the
Palm Photos application, v.1.1.0.20. The API will work only in conjunction
with Photos v.1.1.0.20 which is available on the Tungsten|T3 and Tungsten|E

There's no mention of the Zire 71.

if (err != errNone)
{
err=SysLibLoad(PalmPhotoLibTypeID, PalmPhotoLibCreatorID,
PhotoRefNum); }

Here is my HB++ code and it works well for me on a ZIRE 71.
Perhaps you can check variables values .
iRefNum=LoadLibrary(CameraLib-camL,libr,camL)
Where CameraLib-camL is the PalmPhotoLibName
camL is the PalmPhotoLibCreatorID

PalmCameraLib is the library that controls the camera hardware and allows to preview and capture images. I was able to call and use that one. PalmPhoto library is a set of API to access and manipulate the Photo Application Database. But the photo application comming with the Zire 71 does not support API calls. As Laurens pointed out, it takes the version comming with the T|T3 and T|E which is v.1.1.0.20 I was able to find a library named jcpalm that will allow me to compress my RGB565 data into JPEG. That was my original goal.
