Constructor Detail

XSLFPictureData

protected XSLFPictureData()

Create a new XSLFGraphicData node

XSLFPictureData

public XSLFPictureData(PackagePart part,
                       PackageRelationship rel)

Construct XSLFPictureData from a package part

Parameters:

part - the package part holding the drawing data,

rel - the package relationship holding this drawing, the relationship type must be http://schemas.openxmlformats.org/officeDocument/2006/relationships/image

Method Detail

getData

public byte[] getData()

Gets the picture data as a byte array.

Note, that this call might be expensive since all the picture data is copied into a temporary byte array. You can grab the picture data directly from the underlying package part as follows:
InputStream is = getPackagePart().getInputStream();

Returns:

the Picture data.

getFileName

public String getFileName()

Returns the file name of the image, eg image7.jpg . The original filename isn't always available, but if it can be found it's likely to be in the CTDrawing

suggestFileExtension

public String suggestFileExtension()

Suggests a file extension for this image.

Returns:

the file extension.

getPictureType

public int getPictureType()

Return an integer constant that specifies type of this picture

Returns:

an integer constant that specifies type of this picture
