Method Detail

createFromImage

public static PDImageXObject createFromImage(BufferedImage image)
                                      throws IOException

Creates a new CCITT group 4 (T6) compressed image XObject from a b/w BufferedImage. This compression technique usually results in smaller images than those produced by LosslessFactory#createFromImage(PDDocument, BufferedImage) .

Parameters:

image - the image.

Returns:

a new image XObject.

Throws:

IOException - if there is an error creating the image.

IllegalArgumentException - if the BufferedImage is not a b/w image.

createFromFile

public static PDImageXObject createFromFile(File file)
                                     throws IOException

Creates a new CCITT Fax compressed Image XObject from the first page of a TIFF file.

Parameters:

file - the TIFF file which contains a suitable CCITT compressed image

Returns:

a new Image XObject

Throws:

IOException - if there is an error reading the TIFF data.

createFromFile

public static PDImageXObject createFromFile(File file,
                                            int number)
                                     throws IOException

Creates a new CCITT Fax compressed Image XObject from the first page of a TIFF file.

Parameters:

file - the TIFF file which contains a suitable CCITT compressed image

number - TIFF image number, starting from 0

Returns:

a new Image XObject

Throws:

IOException - if there is an error reading the TIFF data.

createFromSeekableSource

public static PDImageXObject createFromSeekableSource(org.sejda.io.SeekableSource source)
                                               throws IOException

Throws:

IOException

createFromSeekableSource

public static PDImageXObject createFromSeekableSource(org.sejda.io.SeekableSource source,
                                                      int number)
                                               throws IOException

Throws:

IOException
