    Public Properties
     NameDescription
    Public PropertyOverridden. Gets/Sets a value indicating whether the image source's frames should be animated. Setting this property to true will start animation and setting it to false, stops the animation.  
    Public PropertyGets the image natural bounds. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyGets the exception that has been thrown during retrieval of image source data. Returns null if no exception has been thrown. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyGets the number of frames in the image. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyGets/Sets the index of the current frame. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyGets the height of this image source. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyGets the image format of the encoded image. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyGets information about the current image data. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyGets whether the image source is currently being animated. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyOverridden. Returns true if the image source data can change during the lifetime of this image source.  
    Public PropertyGet/Sets the number of times to loop the animation of a multi-frame image. A value of 0 indicates infinite looping. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyGets the current request status of the image source.  
    Public PropertyGets the image's URI (Uniform Resource Identifier).  
    Public PropertyGets the width of this image source. (Inherited from Nevron.Nov.Graphics.NImageSource)

    Protected MethodOverridden. Get description pairs  
    Protected Internal MethodOverridden. Returns image data that should be used for rendering of the image source's current frame. Encoded data is returned for encoded images sources with a single frame. Decoded data is returned for NRaster-based image sources and for encoded images sources with animated frames.  
    Protected Internal MethodGets an immutable image source that can be used as a hash table key for this image source. If this image source is immutable it can return itself as a key. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Protected Internal MethodOverridden. Gets the image source's image data in encoded form.
