`byte[]`	`getData()` Gets the picture data as a byte array.
`java.lang.String`	`getFileName()` Returns the file name of the image, eg image7.jpg .
`java.awt.Dimension`	`getImageDimension()`
`java.awt.Dimension`	`getImageDimensionInPixels()`
`int`	`getIndex()`
`java.io.InputStream`	`getInputStream()` An InputStream to read the picture data directly from the underlying package part
`PictureData.PictureType`	`getType()`
`protected void`	`prepareForCommit()` *PictureData objects store the actual content in the part directly without keeping a copy like all others therefore we need to handle them differently.

```
public XSLFPictureData(PackagePart part)
```
    Construct XSLFPictureData from a package part
    
    Parameters:
    part - the package part holding the drawing data
    Since:
    
    POI 3.14-Beta1
  - XSLFPictureData
```
@Deprecated
public XSLFPictureData(PackagePart part,
                          PackageRelationship rel)
```
    Deprecated. in POI 3.14, scheduled for removal in POI 3.16
    
    Construct XSLFPictureData from a package part
    
    Parameters:
    part - the package part holding the drawing data,

    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.

public java.awt.Dimension getImageDimensionInPixels()
```
    Specified by:
    
    getImageDimensionInPixels in interface PictureData
  - cacheProperties
```
protected void cacheProperties()
```
    Determine and cache image properties
  - prepareForCommit
```
protected void prepareForCommit()
```
    *PictureData objects store the actual content in the part directly without keeping a copy like all others therefore we need to handle them differently.
    
    Overrides:
    
    prepareForCommit in class POIXMLDocumentPart

    java.io.IOException
  - getType
```
public PictureData.PictureType getType()
```
    Specified by:
    
    getType in interface PictureData
  - getIndex
```
public int getIndex()
```
    Returns:
    the 0-based index of this pictures within the picture parts
  - setIndex
```
