Hi Mike,
which Version of the Lib are you using? How much Dynamic Heap do you have?
A gray part in an image is often caused by low memory.

In my App i'll check if it is a PalmOS 5 Device and look for the

jpegLib. So the Programm can still work even if the pnoJpegLib will be
deleted by the user.

Hi Erico,
currently the pnoJpegLib doesn't offer this. Grayscale-Jpegs are returnd
with a depth of 4bit and color with 16bit.
Modifying the lib isn't a good Idea because your app loose the
compartibilty with the official one. (Of course you can create your own
version based on the

i've released an new version of the pnoJpegLib. The Problems with

Hi John,
the lib should work on the Clie Devices (i use it myself on a UX50 and a
TG50). When do you change the color depth. When you start the
Application or when it runs? Maybe you only have to repaint the Image?

you have to convert the bitmap that you get from the jpegLib to a
BitmapV3 Bitmap and set the density to the density of your screen.
The pnoJpegLib contains a function that do this for you.

Your Code-Part looks ok.
Where have you run your Programm? On a real Treo or in the simulator?

Ok, a 160x120 should be small enough.
Is the bitmap compressed? Unfortunatly i've never though about this, so
this could be the failure.
