ImageData class

Defines the ImageData Class. When the object is serialized out as xml, its qualified name is v:imagedata.

Namespace:  DocumentFormat.OpenXml.Vml
Assembly:  DocumentFormat.OpenXml (in DocumentFormat.OpenXml.dll)

public class ImageData : OpenXmlLeafElement

[ISO/IEC 29500-1 1st Edition]

imagedata (Image Data)

This element is used to draw an image that has been loaded from an external source. There is an implied rectangle that is the same size as the image. Any stroke or fill is applied to this implied rectangle.  The stroke is drawn on top of the image.  The fill is behind the image and therefore only visible through transparent areas of the image. Image transparency is either encoded in the file or defined via a color value using the chromakey attribute. Unlike the image element (§14.1.2.10), the imagedata element shall have a parent element.

[Example:

<v:shape style="position:relative;top:1;left:1;width:50;height:50"
  path="m  1000,0 1000,1000 0,1000 x e" fillcolor="blue">
  <v:imagedata src="myimage.gif"/>
</v:shape>

end example]
