• 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 {

• get the Bitmap Image of the web site or remote location

  Hi, yesterday I asked for some ease of image horizontal scorlling with blackberry. It's work very well. Thank you for all.

  But I could not do my job. What I need, that I have to get the Image from a web site (not in the project of ths) and display it in the BB device. I can do this and I get byte array and show the image using BitmapField. But this installation of scrolling does not work with the bitmap field.

  Is is them possible to get my web site dynamic images of the Bitmap object?

  Please be so kind to give me a solution for this issue.

  You can use a browserfield to display web content in your application.  Take a look at the browserfielddemo provided with the BlackBerry JDE for example

  If you ask how to connect to a web site, please see the httpdemo.

  This example shows how to create a scrolling image field.

• How to change the bitmap image in blackberry

  Hello

  1. work on the version of BB storm (9500/9530 Simulator) is v4.7.0.75
  2 opportunity BB JDE 4.7
  3. the request is:

  I display a bitmap image by using the drawBitmap method. now I want to select a portion of the bitmap, and then I need to cut & paste the part somewhere in the screen (MSPaint we have option 'Select').

  is there any method that will make the similar operation (or) any idea to accomplish this in blackberry.

  Thank you

  Sendhil Kumar V

  Take a look at this thread and refers to the J2ME code:

  http://supportforums.BlackBerry.com/Rim/Board/message?board.ID=java_dev&message.ID=24929

  The 'trick' is getARGB() and setARGB().  As long as you check out relevant Bitmap Moose ARGB values, you should be able to create a new Bitmap.  That said, I never did.  Let us know how you go.

• No color for the Bitmap Images after upgrade

  I've updated to ID 2015.4 (Build 11.4.0.90) and now all my bitmap images that have a color not found in the documents. Export a PDF images work as expected. Overview of images of gray as expected.

  What is a change or a bug regarding bitmaps?

  This is a bug. The solution is to turn on view > overprint preview.

• How can I clean the Bitmap Images imported

  Hi, I am using Flash 5. I have imported a .png image sequence and they look pretty rough and bitmap so I wanted to clean them.

  1. what I have to select each frame after import and adjust the settings of the bitmap for each image or I can doo this somewhere so it affects al images?

  2. I can't find the settings to clean up the bitmaps. I thought they would be in the Panel "Properties"?

  3. is it possible to set the pixelation or clean a .swf imported or is it better to clean the sequence before you save it as a .swf?

  Ideally, you should have images cleaned / correctly size / optimised before import you them into Flash.  Once they are in Flash, one thing that you can do that can help how the image appears, especially if manipulate you its size in Flash, is to set the image to allow smoothing.  This can be set using code or can be applied manually to the image in the library do a right-click, selecting Properties and by checking the option to allow smoothing.

• 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).

  NewScreen contains three options, named A, B, and C.

  When I click on any of the option and the user is not connected so I first go to the login screen and after successful connection, I go to the screen details and when I press the back button I go back to NewScreen.

  Now what I want to when I press the back button and come to the NewScreen then image option B Gets the change. And the new image must be in the details page.

• Focus on the bitmap image in a HorizontalFieldManager

  Hello

  I have a bitmap in a HFM, I did focusable (bitmap).

  Problem is when the bitmap is concentrated, the HFM together in turn blue, as if she was herself focused.

  I try to put the bitmap in a value for money that I put in the HFM to limit the focus to the HFM, but it did not work.

  No idea how I can do?

  There is the code:

  HorizontalFieldManager imageHfm = new HorizontalFieldManager(Field.USE_ALL_WIDTH) { protected void paint(Graphics graphics) {        graphics.setBackgroundColor(0x000000);        graphics.clear();        super.paint(graphics);    }};VerticalFieldManager imageVfm = new VerticalFieldManager(Field.FIELD_RIGHT);        Bitmap loginButton = new Bitmap(Bitmap.getBitmapResource("login1.png"), DrawStyle.RIGHT) {            public boolean trackwheelClick(int status, int time) {                connectionWrapper();                return true;            }            };        imageVfm.add(loginButton);        imageHfm.add(imageVfm);
  

  Hello

  While the size of your equal to your bitmapField HorizontalFieldManager().

  You can do this way

  HorizontalFieldManager rowManager = new HorizontalFieldManager() {}
                   
  ' public void sublayout (int width, int height) {}
  Super.sublayout (LooknFeel.Width, bitmap.getBitmapResource("SignIn.png"). GetHeight());
  setExtent (LooknFeel.WIDTH, Bitmap.getBitmapResource("signin.png").getHeight ());
  }
                   
                   
  {} public void paint (Graphics g)
  g.setBackgroundColor (Color.BLACK);
  g.fillRect (0,0,LooknFeel.WIDTH,getHeight ());
  g.Clear ();
  Super.Paint (g);
  }
             
  };

  Here I had only set the height according to my bitmap, you must set the width and height.

  Please let me know if it solves your problem or not.

• Resize the Bitmap image in the image control in flex3

  I'm loading an image in the image at the start control. Then I am a color transformation applying to this image and want to load this bitmap in flex3. That works, but automatic resizing does not work then. If I load another image, then AutoSize works well. Image control does not support resizing of the same bitmap object image?.
  
  Here is the part of the code:
  < mx:Image source = "{imgpath}" id = creationComplete = "imageCompleted ('MyImage'); "x ="20"y ="30"width ="365"height ="440"maintainAspectRatio = 'true '.
  / >
  private void applyColor(event:Event):void {}
  
  myBitmapDataObject = new BitmapData (myImage.height, true, myImage.width, 0x00CCCCCC);
  
  myBitmapDataObject.draw (myImage.content);
  myBitImage = new Bitmap (myBitmapDataObject);
  
  myBitmapDataObject.colorTransform (myBitmapDataObject.rect, new ColorTransform (1, 1, 1, 1, 39, 76, 135, 100));
  myImage.removeChildAt (0)
  myImage.load (myBitImage);
  
  
  }
  
  Any help is appreciated.

  You must create the BitmapData as the size of the original loaded image, not mx:Image height and width. Simply convert you / copy only a portion of the original size that matches the size of the Image. That is to say. whether you have a picture of 400 x 400 and your Image is 100 x 100. Your BitmapData is created at 100 x 100, NOT 400 x 400, you need to do. Everything simply because you resize the Image, does not mean that the underlying BitmapData is also resized.

  Also, in general, addChild would serve after removeChild, never used charge myself. Not sure if this is important.

• a label on the bitmap?

  Hey,.

  I want to show a Bitmap image and write 'in' this tag is there a chance with JDE 4.5?

  I tried with setPosition() of etiquette, but it do not act. Is the only chance to solve the problem, the bitmap as a background?

  Concerning

  Maja

  You can write directly on the bitmap image, using the graphics object. or you can place text on the same place as the bitmap using paint (directly on the screen)
