Default resize an PNG

Please Login to Remove!

Hi,
I want to scale an png Image in myApplication. I have found these ways:
PHP Code:
// 1. way
EncodedImage ei EncodedImage.getEncodedImageResource("splash.png");
BitmapField bmp = new BitmapField(ei.scaleImage32(50,75).getBitmap());   
mainScreen.add(bmp);
            
// 2. way            
EncodedImage image EncodedImage.getEncodedImageResource("splash.png");
image.scaleImage32(50,75);
BitmapField field = new BitmapField();
field.setImage(image); 
mainScreen.add(field); 
But when I try the first way the BB turns off
If I try the second way nothing happens, the image is still the same.

When I try the second way with image = image.scaleImage32(50,75); then I get an Exception.

If I use image.setScale(2); then the image is scaled down. But i want to scale it up. So how do I do this??

Google has no answers for me, an if so then take a look at way 1 and way 2

Maybe someone can help me.

thanks hibbert

Just a guess but I don't think 50 and 75 represent the Fixed32 values you want to use (per the documentation for EncodedImage.scaleImage32().
