• Bitmap image does not appear when other fields added

  Hello

  I have a VerticalFieldManager with a bitmap and a few fields (code below).
  I add to an another VFM then call setBitmapField when the tile is
  downloaded in another thread.

  The code below when the bitmap is set, the other fields, move to the
  right to leave a space for the bitmap image, but the image bitmap is not visible.

  If I remove:

  This.Add (this.authorField);

  and code layout corresponding to sublayout, the bitmap fine watch.

  What I am doing wrong?

  class Item extends VerticalFieldManager {
  
      public BitmapField thumbField;
      public Bitmap image = null;
      private LabelField titleField;
      public LabelField authorField;
  
      public Item(ItemData item) {
  
          this.thumbField = new BitmapField(); 
  
          this.titleField = new LabelField(item.title, FOCUSABLE);
          Font fnt = this.getFont().derive(Font.PLAIN, titleField.getFont().getHeight() - 1);
          this.titleField.setFont(fnt);
  
          this.authorField = new LabelField(item.author);
          Font fnt2 = this.getFont().derive(Font.PLAIN, authorField.getFont().getHeight() - 3);
          this.authorField.setFont(fnt2);
  
          this.add(this.thumbField);
          this.add(this.titleField);
          this.add(this.authorField);
      }
  
      public void setBitmapField(Bitmap _image) {
          this.image = _image;
          this.thumbField.setBitmap(_image);
          this.invalidate();
      }
  
      protected void sublayout(int width, int height) {
  
           if (getFieldCount() > 0) {
  
               BitmapField _thumbField = (BitmapField)getField(0);
               layoutChild(_thumbField, _thumbField.getBitmapWidth(), _thumbField.getBitmapHeight());
               setPositionChild(_thumbField, 0, 0);
  
               int thumbWidth = _thumbField.getWidth();
  
               Field _titleField = getField(1);
               layoutChild(_titleField, width - thumbWidth, _titleField.getHeight());
               setPositionChild(_titleField, thumbWidth + 5, 0); 
  
               Field _authorField = getField(2);
               layoutChild(_authorField, width - thumbWidth, _authorField.getHeight());
               setPositionChild(_authorField, thumbWidth + 5, _titleField.getHeight()); 
  
               setExtent(width, _titleField.getHeight() + _authorField.getHeight() + 2);
           }
       }
  }
  

  I have it! Had to extend Manager rather than VerticalFieldManager. Assumes that the optimization of the resources are so limited in-house as how fields can be arranged. Makes sense.

• 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?

  Here is the code that you sent me.

• Problem with a Bitmap image in a ButtonField (get a 104 NullPointerException error)

  Hi, I'm a beginner in programming BlackBerry Apps, well...

  I tried to create a simple ButtonField customized with a bitmap inside, but I constantly get an error 104 eception: NullPointerException, here is my code to field custom buttond.

  import net.rim.device.api.ui.component.ButtonField;import net.rim.device.api.ui.Graphics;import net.rim.device.api.system.Bitmap;

    public int getPreferredWidth(){
  
                  return 60;        }
  
    public int getPreferredHeight(){
  
        return 60;        }

    PruebaScreen(){
  
        Bitmap imagen = Bitmap.getBitmapResource("res/img/icon.png");     boton = new CustomButtonField(imagen, 0);     add(boton);
  
    }}
  

  I suspect that my problem is due to the method of painting or the page layout, I don't know... I hope someone can help me, thank you very much in advance.

  Check if your getBitmapResource returns any non-null Bitmap image.  Specify the path correctly may take a few tries ("' / res/img/icon.png '," img/icon.png", etc.")

After testing different ways using the BitmapField, I just changed paint the bitmap on the screen instead. More write the paint method and use drawbitmap to draw the bitmap to the screen. Track action wheelball to paint the bitmap can achieve the effect of view.

• Does anyone has knowledge with the import of bitmap images that display perfectly similar to full screen &amp; small

  I created a file of projection for a cd-rom. In the project file, we have added buttons to display full-screen or return to the screen 800 x 600. I imported our company logo which is only available as a bitmap. In the flash program, I put across the 1200 dpi at reduced size logo. However, I noticed that the logo is horrible when scaled to small. But you click on the button to enlarge to full screen, the logo looks great. Flash seems to understand that big logo real size will be read better in full screen, but cannot manage the bitmap well when you scale to a smaller size. So I did a test where I saved the logo in Photoshop at the small size. It looks very small, but when you expand to full screen, the logo appears blurry. In other words, I don't get the best of 2 worlds. Is it possible to have a bitmap image appear visually crisp at full screen or smallscreen? I tried to save at different resolutions such as 500 dpi, 400 dpi and 300 dpi. 300A almost what I want, but seem sweet when you cut them in full screen.

  Depends on a lot of things. Have you tried the 'use smoothing' option in the import of bitmap window? A logo is also still vector exactly due to similar reasons. If you can recreate it in a vector format you wouldn't have problems.

  Another way to take is to calculate for the highest resolution at which the flash runs (usually 1920 x 1200) (very few people have higher resolution screens, and even 1920 x 1200 is a rare case, 1680 x 900 - more likely) and adapted the logo in Photoshop to this resolution.

  This could also be a bug in the version of Flash you use. Another option is to have 2 images to 800 x 600 and full screen and change them accordingly with ACE (you can detect if the player goes to fullscreen or not with ACE)

  But the most likely reason is that you have a bug in your version of Flash... 1200 dpi also seems too gigantic to purposes not printing, maybe the reason why you encounter the bug.

• 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:

              Logger.out(TAG, "It is inside the the image conversion---333333333"+data);
              bmp = Bitmap.createBitmapFromBytes(data, 0, data.length, 1);
              } catch (Exception e) {

• 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

  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.

  Hey there, sorry if this has been asked before:
  I downloaded the new images of my app and removed the 'old' because I changed my user interface. Everything has been approved but the first image shown (beside the description) is still there. When it is selected (for more pictures), it shows all new, which is fine, but I would change the original.

  An example can be seen here: http://appworld.blackberry.com/webstore/content/26864?lang=en

  Now if it's just a matter of not to wait for the appworld update, then I apologize.

  My bad, looks like I just had to give it time.

• PaintBackgound of screen does not paint my bitmap image, but don't paint screen?

  There is something I don't understand with the paint and screen paintBackground.

  I am trying to add a background (Bitmap) image to my final class that extends screen and add a VerticalFieldManager on top of the background image.

  Screen.Paint painted my Bitmap, but hides the VerticalFieldManager:

  protected void paint(Graphics graphics) {
    graphics.clear();
    graphics.drawBitmap(0, 0, deviceWidth, deviceHeight, bgBitmap, 0, 0);
    super.paint(graphics);
  }
  

  However, Screen.paintBackground does not paint my Bitmap or my VerticalFieldManager, and I have a blank white screen?

  protected void paintBackground(Graphics graphics) {
    graphics.clear();
    graphics.drawBitmap(0, 0, deviceWidth, deviceHeight, bgBitmap, 0, 0);
    super.paintBackground(graphics);
  }
  

  The API of the playback screen, I thought paintBackground was the right way to achieve this?

  It's an old bug in BB - do not trust Screen.paintBackground (especially MainScreen.paintBackground!). PaintBackground of your Manager is a much better place for it (I know it is not documented, but if you read the Screen.paintBackground you will see it's substitute Field.paintBackground.).

• Cannot select more than one bitmap image in desktop Animate

  I can't select more than one bitmap image in desktop Animate. Always select the same object, what should I do?

  I guess these bitmaps are on the scene. They are all on the same layer? Who is always selected is large and, perhaps, on top of all the others?

  If the bitmaps are all on one layer, you can separate each in separate layers. Once you do this, you can lock / unlock layers individually so that you can work with one image at a time.

• 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.
