Bitmap.getBitmapResource bug?

• Why not Bitmap.GetBitmapResource)

  I am trying to load a bitmap and I get an IllegalArgumentException in JDE 5.0.0 (have not compiled with previous can).  The file exists in the project, in fact, it is even used for the transfer of the icon of the Application - that work spendidly.  I created the image in Adobe Illustrator and exported as a 100 x 75 pixels format PNG-24. I realized another PNG this way that exists in the project who is responsible (for the unfolded above).  I tried to produce another image and load, with the two images previous (one that works and one that doesn't work) in the project and it fails with this defense, too.

  No restrictions on the inclusion of images in projects?

  Thank you

  Hello

  I don't know, but have you tried to do something like that?

  Since it is a PNG image.

• How to access image stored in Blackberry using Bitmap.getBitmapResource ()?

  I want to access an image stored in Blackberry, say instead of "store/home/user/image.png".

  Now I can access the image as,

  String filePath = "file:///store/home/user/image.png;
  Bitmap image = Bitmap.getBitmapResource(filePath);
  BitmapField bitmapField = new BitmapField(image, BitmapField.FOCUSABLE);
  

  OR

  I have to access

  String filePath = "file:///store/home/user/image.png;
    FileConnection fconn = (FileConnection)Connector.open(filePath, Connector.READ);
    if (fconn.exists())
    {
                  ........
                  ........                           
  
       input.close();
       fconn.close();                            
  
    }
  

  I am able to access the image using the second way, but I want to know that can I access using 'Bitmap.getBitmapResource (filePath)?

• Bitmap.getBitmapResource (...) does not find my file?

  Hi all, I'm a 1st year student at the University of Warwick (United Kingdom) and I'm writing a small application for the Blackberry Storm, but I can't get my code to use just...

  Bitmap image = Bitmap.getBitmapResource ("c.gif");

  BitmapField bField = new BitmapField (image, BitmapField.FOCUSABLE);

  Add (bField);

  if(image == null) {Add (new RichTextField ("zero!")) ;}

  ^^ the snippet above is what I wrote, as far as I can see it is all very well, and the c.gif file is in the same directory as the source .java code when I Isaiah to compile the project (in the RIM JDE)

  When I run my app in the Simulator, rather than the displayed image, I just get "null!" printed...

  I don't know I'm just something dumb/obvious but I tried to move the .gif to different folders, but I can't make it work

  Thanks for reading this,

  You have added the file to the project?

• Malfunction Bitmap.getBitmapResource

  I have an image in the res project folder and load the bitmap as the background of the screen with Bitmap.getBitmapResource ("pic.png").

  On a device, it works and finds the image in the res folder, but on another device, it will return null and can't seem to find the «pic.png» When I put the pic.png in the res and the src folder, it works on both devices.

  No idea why this is happening?

  It seems to be resolved when I place the files in a subfolder of the folder res for example folder named img and then access it with the img/pic.png path. The problem seems to be that in the root folder.

  Thanks anyway

  the red line causes this problem, can someone help me out on this please? is there another method I can try to achieve the same result?

  Thank you...

  Hello

  you use scaleImage32 the wrong way, try this that method or rather. You can also resize bitmap image without code it first.

• How to access an image button (bitmap image)?

  Hello

  I have two questions.

  1 .i have over the path navigationClick() method, but always attack don't know, how to get the id of the clicked field?

  2. How can I put a label with this bitmapField?

  Here is my code.

  Image bitmap myBitmap = Bitmap.getBitmapResource ("Order.jpg");
  BitmapField myBitmapField = new BitmapField (myBitmap, BitmapField.FOCUSABLE);
      
              
  Image bitmap deliverBitmap = Bitmap.getBitmapResource ("Deliver.jpg");
  BitmapField deliverBitmapField = new BitmapField (deliverBitmap, BitmapField.FOCUSABLE);

  protected boolean navigationClick (int status, int time)
  {
  System.out.println ("key =" + status);
      
  Returns true;
  }

  No, I mean that you set your variables of the bitmap to the screen, not only in its constructor.

  Focus on the ground = getLeafFieldWithFocus();

  If (focus.equals (bitmapfield1) {;} doStuff () else if...})

• How to dynamically set the width of the bitmap as mobile size and adjust accordingly the photo.

  I have the bitmap image. Now, I want the bitmap to the screen but its size should be as mobile width and adjust the picture accordingly. For the former I enlarge it should look like small small mobile screen.

  My code but its not working.

  public static BitmapField getHeader() throws NullPointerException {}
  Bitmap b = Bitmap.getBitmapResource("img/logo.jpg");
  return (new BitmapField (b, Field.FIELD_HCENTER) {})
  Protected Sub layout (int width, int height) {}
  setExtent (365, 80);
  }
  });
  }

  You will need to put the image yourself to match the dimensions you need.

• custom bitmaps field not change image when click on

  I created a custom bitmap field and I change the image on the center of my field of custom bitmaps and unfocus

  but when I implement the method of navigation click to change the image when you click on this image does not change...

  my custom bitmap field filed only to focus or unfocus on the image does not change my field of custom bitmaps.

  Bitmap onfocus = Bitmap.getBitmapResource("111.png");

                           return true;
  
                       }
  
                  };
  add(mybutton1);

      }
  
  }
  

  When you debug this code, which of your methods of navigationClick, is actually used?

  When you expect the bitmap change, the code should lead object so that to happen.  Paint running?  This is the correct Bitmap painting?

  If you answer these questions, I think that you figure to yourself what is the problem.

• Bitmap class: how to use the directories under the directory res/img?

  I have the following image resources structure.

  RES/img

  I added two subdirectories of img, hi_res and low_res, so my resource structure looks like:

  RES/img/hi_res

  RES/img/low_res

  When I create a Bitmap object, I want to use a PNG image under hi_res such as:

  Bitmap bg = Bitmap.getBitmapResource("hi_res/cool.png");
  

  However, I return the following error in the Console:

  [0,0] CAFETERIA: could not find hi_res/cool.png

  I tried the structure of the whole package such as img/hi_res/cool.png and who fired a similar error. How to properly use packages in the res directory?

  Well done.

• Field bitmap button

  Hello...

  Yes, I looked in other posts.  And trying to disect the sample APP CustomButton.  But, the image does not change the focus for this, and really, I had a hard time to work with it.

  So, after several hours, I write...

  I would like to make my button below clickable so that it plays a sound image and changes on focus.  However, I have not yet found a strategy that I could implement.

  Can someone provide some guidance?  The error that I get with the implementation ŒUVRE FieldChangeListener when I try to extend the UiApplication is that...

  ....... The SmartCord type must implement the inherited abstract method FieldChangeListener.fieldChanged (field, int)

  So clearly something is wrong and I have a bad strategy, but I have no idea what.

  I use absolute available to resize the image according to the size of the screen

  Thanks for the tips...

• 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.
