Class TIFFEncodedImage

java.lang.Object
  net.rim.device.api.system.EncodedImage
      net.rim.device.api.system.TIFFEncodedImage

public final class TIFFEncodedImage
extends EncodedImage

Represents an image encoded in the TIFF format.

To create a TIFFEncodedImage instance, use EncodedImage.createEncodedImage(byte[],int,int), which accepts a java byte array containing the encoding of an image.

An image encoding can be obtained by either of the following methods:

First, when an image is added to a project in the IDE, the image resource becomes available to the developer.

Second, the image encoding can be obtained manually by converting the binary image file to a java byte array. This is accomplished using the following procedure:

1. Using a binary file converter, such as xxd, convert the image to a C-style byte array.
2. Open the target file and search for the string "0x".
3. Replace the string with the following "(byte)0x".
4. Adjust the array declaration at the top of the file to conform to Java standards.
5. Remove the following string from the bottom of the file "unsigned int input_file_name_len = XXXX".

If done correctly, the file will contain a valid java byte array containing the image encoding.
