XWPFPictureData

protected XWPFPictureData()

Create a new XWPFGraphicData node

XWPFPictureData

public XWPFPictureData(PackagePart part)

Construct XWPFPictureData from a package part

Parameters:

part - the package part holding the drawing data,

Since:

POI 3.14-Beta1

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

Throws:

java.io.IOException - a subclass may throw an IOException when a document is read

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

Returns:

an integer constant that specifies type of this picture, returns 0 if an unknown type
