TiffImageData

             protected TiffImageData
             (URL url, boolean recoverFromImageError, int page, boolean direct)
            

Creates TIFF image data to be loaded from a URL.

Parameters:

url - source URL, not null

recoverFromImageError - whether decoding should recover from malformed image data

page - one-based TIFF page number

direct - whether to preserve directly embeddable TIFF data

TiffImageData

             protected TiffImageData
             (byte[] bytes, boolean recoverFromImageError, int page, boolean direct)
            

Creates TIFF image data from encoded bytes.

Parameters:

bytes - encoded TIFF bytes; the array is retained

recoverFromImageError - whether decoding should recover from malformed image data

page - one-based TIFF page number

direct - whether to preserve directly embeddable TIFF data

Method Details

getNumberOfPages

             public static int getNumberOfPages
             (RandomAccessFileOrArray raf)
            

Gets the number of pages the TIFF document has.

Parameters:

raf - a RandomAccessFileOrArray containing a TIFF image.

Returns:

the number of pages.

getNumberOfPages

             public static int getNumberOfPages
             (byte[] bytes)
            

Gets the number of pages the TIFF document has.

Parameters:

bytes - a byte array containing a TIFF image.

Returns:

the number of pages.

isRecoverFromImageError

             public boolean isRecoverFromImageError()
            

Checks whether decoding may recover from image errors.

Returns:

true when recovery is enabled

getPage

             public int getPage()
            

Gets the selected TIFF page number.

Returns:

one-based page number

isDirect

             public boolean isDirect()
            

Checks whether direct TIFF embedding was requested.

Returns:

true when direct embedding was requested

setOriginalType

             (ImageType originalType)
            

Sets the detected original image type.

Parameters:

originalType - original image type
