Method Detail

createFromStream

public static PDImageXObject createFromStream(PDDocument document,
                                              InputStream stream)
                                       throws IOException

Creates a new JPEG Image XObject from an input stream containing JPEG data. The input stream data will be preserved and embedded in the PDF file without modification.

Parameters:

document - the document where the image will be created

stream - a stream of JPEG data

Returns:

a new Image XObject

Throws:

IOException - if the input stream cannot be read

createFromImage

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

Creates a new JPEG Image XObject from a Buffered Image.

Parameters:

document - the document where the image will be created

image - the buffered image to embed

Returns:

a new Image XObject

Throws:

IOException - if the JPEG data cannot be written

createFromImage

public static PDImageXObject createFromImage(PDDocument document,
                                             android.graphics.Bitmap image,
                                             float quality)
                                      throws IOException

Creates a new JPEG Image XObject from a Buffered Image and a given quality. The image will be created at 72 DPI.

Parameters:

document - the document where the image will be created

image - the buffered image to embed

quality - the desired JPEG compression quality

Returns:

a new Image XObject

Throws:

IOException - if the JPEG data cannot be written

createFromImage

public static PDImageXObject createFromImage(PDDocument document,
                                             android.graphics.Bitmap image,
                                             float quality,
                                             int dpi)
                                      throws IOException
