Method Details

getDpi

private static int getDpi(TIFFField fd,
 int resolutionUnit)

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

private 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

private static Image getTiffImageColor(TIFFDirectory dir,
 RandomAccessFileOrArray s)

getArrayLongShort

private static long[] getArrayLongShort(TIFFDirectory dir,
 int tag)

decodePackbits

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

inflate

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