    Public PropertyBoundsGets the image natural bounds. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyDataExceptionGets 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 PropertyEmbeddedGets whether the image file is embedded or linked.  
    Public PropertyFrameCountGets the number of frames in the image. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyFrameIndexGets/Sets the index of the current frame. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyHeightGets the height of this image source. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyImageFormatGets the image format of the encoded image. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyImageInfoGets information about the current image data. (Inherited from Nevron.Nov.Graphics.NImageSource)
    Public PropertyIsAnimatingGets whether the image source is currently being animated. (Inherited from Nevron.Nov.Graphics.NEncodedImageSource)
    Public PropertyIsMutableReturns true if the image source data can change during the lifetime of this image source. (Inherited from Nevron.Nov.Graphics.NUriImageSource)
    Public PropertyLoopCountGet/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 PropertyRequestStatusGets the current request status of the image source. (Inherited from Nevron.Nov.Graphics.NUriImageSource)
    Public PropertyUriGets the image's URI (Uniform Resource Identifier). (Inherited from Nevron.Nov.Graphics.NUriImageSource)
    Public PropertyWidthGets the width of this image source. (Inherited from Nevron.Nov.Graphics.NImageSource)
