It was a nice try, but it still doesn't work. Does anyone know the reason for this IllegalArgumentException? (API 4.5.0 net.rim.device.api.ui.Graphics: line 1325)

I guess it's safe to assume their tiff support is broken. This isn't the first time their API has sent me on a wild goose chase.

Either way, thanks for your help.

If you don't mind do you think you can post up the TIFF image?

I must be blind. I can't see how to post an attachment.

RIght side, under "Tags"

When posting, to the right of the area you type into, there is an Attachments panel, with a Browse Button, plus Remove/Add Attachment links.

For some reason i don't have that option. I posted the tiff on filedropper. Here's the link: http://www.filedropper.com/a_35

OK, got it, and got your problem.

Then I shrunk the file down, and problem went away.

I suspect a problem in the decoding program, they probably assumed some arbitrary maximum size and barf if it is bigger than that.

I would raise this on Issue Tracker, but I don't think you will have much joy with installed devices.  So I would see if you can scale down the image you send to the BlackBerry.  Alternatively, I don't think Tiff is too hard, perhaps you can decode it yourself?

I believe it is definitely a bug because if you debug into the getBitmap function it actually creates the Bitmap but somewhere it breaks but otherwise it does load and decode.

Thanks for the help! For the record, here's a working snippet of code:

protected void paint(Graphics graphics) {
    EncodedImage image = EncodedImage.getEncodedImageResource("A.TIF");

    int currentWidthFixed32 = Fixed32.toFP(image.getWidth());
    int currentHeightFixed32 = Fixed32.toFP(image.getHeight());

    int requiredWidthFixed32 = Fixed32.toFP(graphics.getScreenWidth());
    int requiredHeightFixed32 = Fixed32.toFP(graphics.getScreenHeight());

    int scaleXFixed32 = Fixed32.div(currentWidthFixed32, requiredWidthFixed32);
    int scaleYFixed32 = Fixed32.div(currentHeightFixed32, requiredHeightFixed32);

    EncodedImage scaledImage = image.scaleImage32(scaleXFixed32, scaleYFixed32);
    graphics.drawImage(0, 0, scaledImage.getWidth(), scaledImage.getHeight(), scaledImage, 0, 0, 0);
}

Excellent, thanks for the code snippet.

Can you mark this as solved?
