i have created an image from the image url(lcdui image)

HttpConnection c = (HttpConnection) Connector.open(imageurl);
int len = (int)c.getLength();

if (len > 0) 
{
is = c.openDataInputStream();
byte[] data = new byte[len];
is.readFully(data);

img = Image.createImage(data, 0, len);

i want to set height and width to this?and i want to display

You can’t set width and height to Image. But, you can resize the image using the below method.

public Image resizeImage(Image src, int screenHeight, int screenWidth) {
        int srcWidth = src.getWidth();

        int srcHeight = src.getHeight();
        Image tmp = Image.createImage(screenWidth, srcHeight);
        Graphics g = tmp.getGraphics();
        int ratio = (srcWidth << 16) / screenWidth;
        int pos = ratio / 2;

        //Horizontal Resize        

        for (int index = 0; index < screenWidth; index++) {
            g.setClip(index, 0, 1, srcHeight);
            g.drawImage(src, index - (pos >> 16), 0);
            pos += ratio;
        }

        Image resizedImage = Image.createImage(screenWidth, screenHeight);
        g = resizedImage.getGraphics();
        ratio = (srcHeight << 16) / screenHeight;
        pos = ratio / 2;

        //Vertical resize

        for (int index = 0; index < screenHeight; index++) {
            g.setClip(0, index, screenWidth, 1);
            g.drawImage(tmp, 0, index - (pos >> 16));
            pos += ratio;
        }
        return resizedImage;

    }
