I'm studying jpegArmlets too.
I've tried annoTester. I'll test "testARmlet2" very soon. For annoTester, I
just modified the line:
err=VFSFileOpen(volRefNum,"/2.jpg",vfsModeRead,&fp);
and installed the compiled file "starter.prc" into my Zire71 and a jpeg file
"2.jpg" into root directory of my SD card. The image can be displayed at a
speed much faster than JpegLibPalm I've tested.
But I can't get it working on Simulator, even though I copied the bundled
"ARMlet.dll" and "ARMletC.dll" into the simulator directory.
Just black on screen without hang. I can just click home to return to menu.
Any advice and suggesting for this library. Thank you!
