Hi ,

  I have an image with 2.19 MB on my blackberry gallery. When I open it using native, it srinks the image perfectly to the screen and shows

I need to do the same when the user clicks on my image inside my application. when i used the code provided by Bikas, it fits to screen but cant see the entire image.. may be first half streched.

can anyone help me how to fit the bigger size image to the screen? Basically shrink it with gud display to the screen?

Thanks

Bhuvana

I'm having some trouble getting this working... I just want to scale my image down by half. When I check getWidth and getHeight after doing scaleImage32 the image is the same dimensions. Am I doing something wrong here. I tried calling it with 

scaleImage(data, 0.5); 

public static byte[] scaleImage(byte[] data, double scale) {
EncodedImage image = EncodedImage.createEncodedImage(data, 0, data.length);

int currentWidth32 = Fixed32.toFP(image.getWidth());
int currentHeight32 = Fixed32.toFP(image.getHeight());

int requiredWidth = (int) (image.getWidth() * scale);
int requiredHeight = (int) (image.getHeight() * scale);

int requiredWidth32 = Fixed32.toFP(requiredWidth);
int requiredHeight32 = Fixed32.toFP(requiredHeight);

int scaleXFixed32 = Fixed32.div(currentWidth32, requiredWidth32);
int scaleYFixed32 = Fixed32.div(currentHeight32, requiredHeight32);

EncodedImage scaledImage = image.scaleImage32(scaleXFixed32, scaleYFixed32);
Utils.log("Image now has size: " + scaledImage.getWidth() + "x" + scaledImage.getHeight());
return scaledImage.getData();
}

Does the code here actually shrink the file size? I should perhaps ask that.

It can.  But see your other posts before using it.
