J2ME : Anybody had a .JPG work in a midlet from T6xx phone..

Archived from groups: alt.cellular.ericsson (More info?)

I have a midlet that gets an IOException when using
Image.CreateImage() to load .JPG's on Sony Ericsson emulators with the
T6xx phone device profiles.

This same code works fine when the .JPG's are switched to .PNG's & has
worked elsewhere on Motorola & Sprint PCS Vision phones & emulators
with .JPG's.

I've tried .JPG's made by QuickTime Windows, MS Paint, Linux
ImageMagick all to no avail.

If anybody has had .JPG's to work on T6xx phones or emulators please
share your process for creating them.

No PNGs are much larger (10X) than JPGs for photos.

I write commercial midlets.

The graphics that are stored as PNGs are exactly that graphics, not
photographs.

The Sony Ericsson MIDP 2.0 phones support JPG fine.

I can only conclude that Sony Ericsson MIDP 1.0 phones are a poor
implementation.

Every other MIDP 1.0 phone I've ever dealt with from Motorola, Nokia,
Samsung & Sanyo has JPEG support.

Guess this is why most apps seem to use PNG, so they will work on SE
MIDP1.0 phones.

Most apps ?

Any midlet for photos is just going to ignore the SE MIDP 1.0 phones
rather than have multi hundred KB downloads.

There's a reason that the newer MIDP 2.0 SE phones finally added JPEG
support.
