TiffImage

public TiffImage()
Method Detail

getNumberOfPages

public static int getNumberOfPages(RandomAccessFileOrArray s)
Gets the number of pages the TIFF document has.

Parameters:
s - the file source
Returns:
the number of pages

getTiffImage

public static Image getTiffImage(RandomAccessFileOrArray s,
                                 boolean recoverFromImageError,
                                 int page,
                                 boolean direct)

getTiffImage

public static Image getTiffImage(RandomAccessFileOrArray s,
                                 boolean recoverFromImageError,
                                 int page)

getTiffImage

public static Image getTiffImage(RandomAccessFileOrArray s,
                                 int page)
Reads a page from a TIFF image. Direct mode is not used.

Parameters:
s - the file source
page - the page to get. The first page is 1
Returns:
the Image

getTiffImage

public static Image getTiffImage(RandomAccessFileOrArray s,
                                 int page,
                                 boolean direct)
Reads a page from a TIFF image.

Parameters:
s - the file source
page - the page to get. The first page is 1
direct - for single strip, CCITT images, generate the image by direct byte copying. It's faster but may not work every time
Returns:
the Image

getTiffImageColor

protected static Image getTiffImageColor(TIFFDirectory dir,
                                         RandomAccessFileOrArray s)

decodePackbits

public static void decodePackbits(byte[] data,
                                  byte[] dst)

inflate

public static void inflate(byte[] deflated,
                           byte[] inflated)

applyPredictor

public static void applyPredictor(byte[] uncompData,
                                  int predictor,
                                  int w,
                                  int h,
                                  int samplesPerPixel)
