Method Detail

• configure

  public void configure(java.lang.String option,
                        java.lang.String value)

  Description copied from interface: BitmapWriter
  This method will be called before writing begins. It is used to set common attributes to file writers. Currently supported keywords include:

  • "compression"
  • "channeltype": "byte", "short", "half", "float"

  Note that this method should not fail if its input is not supported or invalid. It should gracefully ignore the error and keep its default state.

  Specified by:

  configure in interface BitmapWriter

• openFile

  public void openFile(java.lang.String filename)
                throws java.io.IOException

  Description copied from interface: BitmapWriter
  Open a handle to the specified file for writing. If the writer buffers the image and writes it on close, then the filename should be stored.

  Specified by:

  openFile in interface BitmapWriter

  Parameters:

  filename - filename to write the bitmap to

  Throws:

  java.io.IOException - thrown if an I/O error occurs

• writeHeader

  public void writeHeader(int width,
                          int height,
                          int tileSize)
                   throws java.io.IOException,
                          java.lang.UnsupportedOperationException

  Description copied from interface: BitmapWriter
  Write the bitmap header. This may be defered if the image is buffered for writing all at once on close. Note that if tile size is positive, data sent to this class is guarenteed to arrive in tiles of that size (except at borders). Otherwise, it should be assumed that the data is random, and that it may overlap. The writer should then either throw an error or start buffering data manually.

  Specified by:

  writeHeader in interface BitmapWriter

  Parameters:

  width - image width

  height - image height

  tileSize - tile size or 0 if the image will not be sent in tiled form

  Throws:

  java.io.IOException - thrown if an I/O error occurs

  java.lang.UnsupportedOperationException - thrown if this writer does not support writing the image with the supplied tile size

• writeTile

  public void writeTile(int x,
                        int y,
                        int w,
                        int h,
                        Color[] color,
                        float[] alpha)
                 throws java.io.IOException

  Description copied from interface: BitmapWriter
  Write a tile of data. Note that this method may be called by more than one thread, so it should be made thread-safe if possible.

  Specified by:

  writeTile in interface BitmapWriter

  Parameters:

  x - tile x coordinate

  y - tile y coordinate

  w - tile width

  h - tile height

  color - color data

  alpha - alpha data

  Throws:

  java.io.IOException - thrown if an I/O error occurs

• closeFile

  public void closeFile()
                 throws java.io.IOException

  Description copied from interface: BitmapWriter
  Close the file, this completes the bitmap writing process.

  Specified by:

  closeFile in interface BitmapWriter

  Throws:

  java.io.IOException - thrown if an I/O error occurs
