BinaryPartAbstractImage

public BinaryPartAbstractImage(PartName partName)
                        throws InvalidFormatException

Throws:

InvalidFormatException

BinaryPartAbstractImage

public BinaryPartAbstractImage(ExternalTarget externalTarget)

Method Details

getImageInfo

@Deprecated
public org.apache.xmlgraphics.image.loader.ImageInfo getImageInfo()

Deprecated.

setImageInfo

@Deprecated
public void setImageInfo(org.apache.xmlgraphics.image.loader.ImageInfo imageInfo)

Deprecated.

getRels

public List<Relationship> getRels()

getRelLast

public Relationship getRelLast()

setDensity

public static void setDensity(int density)

Set the resolution at which a PDF or EPS is converted to PNG. For best quality, you should set this to match the target output device. Higher densities (eg 600) give better quality, at the expense of conversion time (and file size).

Parameters:

density -

getImageManager

protected static org.apache.xmlgraphics.image.loader.ImageManager getImageManager()

Create an image part from the provided byte array, attach it to the source part (eg the main document part, a header part etc), and return it. Works for both docx and pptx. Note: this method creates a temp file (and attempts to delete it). That's because it uses org.apache.xmlgraphics

Parameters:

opcPackage -

sourcePart -

bytes -

Returns:

Throws:

Exception

Create an image part from the provided byte array, attach it to the source part (eg the main document part, a header part etc), and return it. Works for both docx and pptx. Knowing the MIME type allows you to avoid ImageInfo, but you'll probably also need to know the image dimensions

Parameters:

opcPackage -

sourcePart -

bytes -

mime - MIME type eg image/png

ext - filename extension eg png

Returns:

Throws:

Exception

sourcePart -

bytes -

mime - MIME type eg image/png

Returns:

url -

Returns:

Throws:

Exception
