• How to convert the Bitmap Image in BlackBerry

  Hello

  In my application, I get the picture from the server. Now, I want to convert this Bitmap Image to display on the screen. For this I use below codes. But it doesn't give me the same image does not mean with the clarity and the exact size. He's smaller than the picture.

  I used the codes below:

  private Bitmap getBitmapFromImg(Image img) {
          Bitmap bmp = null;
          try {
              Logger.out(TAG, "It is inside the the image conversion        " +img);
              Image image = Image.createImage(img);
              byte[] data = BMPGenerator.encodeBMP(image);
              Logger.out(TAG, "It is inside the the image conversion---333333333"+data);
              bmp = Bitmap.createBitmapFromBytes(data, 0, data.length, 1);
              } catch (Exception e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
          return bmp;
          // TODO Auto-generated method stub
      }
  

  Here is the BMPGenerator class:

  public final class BMPGenerator {
  
          /**
           * @param image
           * @return

           */
          public static byte[] encodeBMP(Image image) throws IOException {
                  int width = image.getWidth();
                  int height = image.getHeight();
                  int[] rgb = new int[height * width];
                  image.getRGB(rgb, 0, width, 0, 0, width, height);
                  return encodeBMP(rgb, width, height);
          }

  Why you want to use a bmp image?
  You can just use png, jpg or whatever of the original image is.
  If there is a situation where you need the bitmap image call http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/system/EncodedImage.html#getBi...

• Change the bitmap image, remove background in Flash CS4?

  HI people, I tried to slide in Photoshop, a layer with a transparent background, and image but it becomes white in Flash, so I imported the psd image. However, the black background interfere with the placement of the image. In OLD flash, there was formerly a magic wand and the ability to select areas of the bitmap and delete, but it seems that the feature is now missing or hidden in the new flash.  I transformed the image bitmap and I don't want to follow, because it's a picture. So, without tracking, how you change the image as I am doing?

  Thank you

  Jeff

  The magic wand is in the same place in CS4 (select Lasso, and then it is in the area of the toolbar options).

• How to change the background image in a model.

  I have Startboot Business Casual open in DW.  It has a brick background.  I want to replace it with a few trees and clouds.  I did a picture of decent size and I've replaced the image, bg.jpg in files, but nothing has changed.  Do I have to change the code?  And if so, how?  Or should I remove the background image for each page and then replace it with the new image?

  Did you do a refresh of the page? You are testing in a real browser?
