Constructor Detail

XWPFPictureData

protected XWPFPictureData()
Create a new XWPFGraphicData node


XWPFPictureData

public XWPFPictureData(PackagePart part,
                       PackageRelationship rel)
Construct XWPFPictureData 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

onDocumentRead

protected void onDocumentRead()
                       throws java.io.IOException
Description copied from class: POIXMLDocumentPart
Fired when a package part is read

Overrides:
onDocumentRead in class POIXMLDocumentPart

java.io.IOException

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 java.lang.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 java.lang.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
