Method Detail

• writeImage

  public static boolean writeImage(BufferedImage image,
                   String filename,
                   int dpi)
                            throws IOException

  Writes a buffered image to a file using the given image format. See writeImage(BufferedImage image, String formatName, OutputStream output, int dpi, float quality) for more details.

  Parameters:

  image - the image to be written

  filename - used to construct the filename for the individual image. Its suffix will be used as the image format.

  dpi - the resolution in dpi (dots per inch) to be used in metadata

  Returns:

  true if the image file was produced, false if there was an error.

  Throws:

  IOException - if an I/O error occurs

                            throws IOException

  Deprecated. use writeImage(BufferedImage image, String filename, int dpi), which uses the full filename instead of just the prefix.
  Writes a buffered image to a file using the given image format. See writeImage(BufferedImage image, String formatName, OutputStream output, int dpi, float quality) for more details.

  Parameters:

  image - the image to be written

  formatName - the target format (ex. "png") which is also the suffix for the filename

  filename - used to construct the filename for the individual image. The formatName parameter will be used as the suffix.

  dpi - the resolution in dpi (dots per inch) to be used in metadata

  Returns:

  true if the image file was produced, false if there was an error.

  Throws:

  IOException - if an I/O error occurs

  public static boolean writeImage(BufferedImage image,
                   String formatName,
                   OutputStream output)
                            throws IOException

  Writes a buffered image to a file using the given image format. See writeImage(BufferedImage image, String formatName, OutputStream output, int dpi, float quality) for more details.

  Parameters:

  image - the image to be written

  formatName - the target format (ex. "png")

  output - the output stream to be used for writing

  Returns:

  true if the image file was produced, false if there was an error.

  Throws:

  IOException - if an I/O error occurs

                            throws IOException

  Writes a buffered image to a file using the given image format. See writeImage(BufferedImage image, String formatName, OutputStream output, int dpi, float quality) for more details.

  Parameters:

  image - the image to be written

  formatName - the target format (ex. "png")

  output - the output stream to be used for writing

  dpi - the resolution in dpi (dots per inch) to be used in metadata

  Returns:

  true if the image file was produced, false if there was an error.

  Throws:

• writeImage

  public static boolean writeImage(BufferedImage image,
                   String formatName,
                   OutputStream output,
                   int dpi,
                   float quality)
                            throws IOException

  Writes a buffered image to a file using the given image format. Compression is fixed for PNG, GIF, BMP and WBMP, dependent of the quality parameter for JPG, and dependent of bit count for TIFF (a bitonal image will be compressed with CCITT G4, a color image with LZW). Creating a TIFF image is only supported if the jai_imageio library is in the class path.

  Parameters:

  image - the image to be written

  formatName - the target format (ex. "png")

  output - the output stream to be used for writing

  dpi - the resolution in dpi (dots per inch) to be used in metadata

  quality - quality to be used when compressing the image (0 < quality < 1.0f)

  Returns:

  true if the image file was produced, false if there was an error.

  Throws:

  IOException - if an I/O error occurs
