Method Detail

createFromImage

public static PDImageXObject createFromImage(PDDocument document,
                                             Bitmap image)
                                      throws IOException

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

Parameters:

document - the document to create the image as part of.

image - the image.

Returns:

a new image XObject.

Throws:

IOException - if there is an error creating the image.

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

createFromByteArray

public static PDImageXObject createFromByteArray(PDDocument document,
                                                 byte[] byteArray)
                                          throws IOException

Creates a new CCITT Fax compressed image XObject from a specific image of a TIFF file stored in a byte array. Only single-strip CCITT T4 or T6 compressed TIFF files are supported. If you're not sure what TIFF files you have, use LosslessFactory.createFromImage(PDDocument, Bitmap) or createFromImage(PDDocument, Bitmap) instead.

Parameters:

document - the document to create the image as part of.

byteArray - the TIFF file in a byte array which contains a suitable CCITT compressed image

Returns:

a new Image XObject

Throws:

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

createFromByteArray

public static PDImageXObject createFromByteArray(PDDocument document,
                                                 byte[] byteArray,
                                                 int number)
                                          throws IOException

Creates a new CCITT Fax compressed image XObject from a specific image of a TIFF file stored in a byte array. Only single-strip CCITT T4 or T6 compressed TIFF files are supported. If you're not sure what TIFF files you have, use LosslessFactory.createFromImage(PDDocument, Bitmap) or createFromImage(PDDocument, Bitmap) instead.

Parameters:

document - the document to create the image as part of.

byteArray - the TIFF file in a byte array 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.

createFromRandomAccess

@Deprecated
public static PDImageXObject createFromRandomAccess(PDDocument document,
                                                    RandomAccess reader)
                                             throws IOException

Deprecated.

Use createFromFile(PDDocument, File) instead.

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

Parameters:

document - the document to create the image as part of.

reader - the random access 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.

createFromRandomAccess

@Deprecated
public static PDImageXObject createFromRandomAccess(PDDocument document,
                                                    RandomAccess reader,
                                                    int number)
                                             throws IOException

Deprecated.

Use createFromFile(PDDocument, File, int) instead.

Creates a new CCITT Fax compressed image XObject from a specific image of a TIFF file.

Parameters:

document - the document to create the image as part of.

reader - the random access TIFF file which contains a suitable CCITT compressed image

number - TIFF image number, starting from 0

Returns:

a new image XObject, or null if no such page

Throws:

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

createFromFile

public static PDImageXObject createFromFile(PDDocument document,
                                            File file)
                                     throws IOException

Creates a new CCITT Fax compressed image XObject from the first image of a TIFF file. Only single-strip CCITT T4 or T6 compressed TIFF files are supported. If you're not sure what TIFF files you have, use LosslessFactory.createFromImage(com.tom_roush.pdfbox.pdmodel.PDDocument, android.graphics.Bitmap) or createFromImage(PDDocument, Bitmap) instead.

Parameters:

document - the document to create the image as part of.

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.

                                            int number)
                                     throws IOException

Creates a new CCITT Fax compressed image XObject from a specific image of a TIFF file. Only single-strip CCITT T4 or T6 compressed TIFF files are supported. If you're not sure what TIFF files you have, use LosslessFactory.createFromImage(PDDocument, Bitmap) or createFromImage(PDDocument, Bitmap) instead.

Parameters:
