Fields  Properties  Methods  Events

The following tables list the members exposed by NEncodedImageSource.

Protected Fields
Protected Fieldm_fUniformAlphaIf all pixels of the image have the same alpha value, the field stores the alpha value as a number in the range [0, 1]. If the alpha value varies accross pixels, the value must be -1. If not calculated yet, the value must be -2. (Inherited from Nevron.Nov.Graphics.NImageSource)
Protected Fieldm_ImageCacheLock (Inherited from Nevron.Nov.Graphics.NImageSource)
Public Properties
Public PropertyAnimateFramesGets/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 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 PropertyFrameIndexGets/Sets the index of the current frame.  
Public PropertyHeightGets the height of this image source. (Inherited from Nevron.Nov.Graphics.NImageSource)
Public PropertyImageFormatGets the image format of the encoded image.  
Public PropertyImageInfoGets information about the current image data. (Inherited from Nevron.Nov.Graphics.NImageSource)
Public PropertyIsAnimatingGets whether the image source is currently being animated.  
Public PropertyIsMutableOverridden. Returns true if the image source data can change during the lifetime of this image source  
Public PropertyLoopCountGet/Sets the number of times to loop the animation of a multi-frame image. A value of 0 indicates infinite looping.  
Public PropertyWidthGets the width of this image source. (Inherited from Nevron.Nov.Graphics.NImageSource)
Public Methods
Public MethodCopyAnimationPropertiesCopies all properties related to animation from the given image source to this image source.  
Public MethodCreateRasterCreates a new raster from the native image data of this source. (Inherited from Nevron.Nov.Graphics.NImageSource)

Public MethodTryGetUniformAlphaDetermines whether all of the image's pixels have the same alpha value and obtains this alpha value. (Inherited from Nevron.Nov.Graphics.NImageSource)
Protected Methods
Protected MethodClearCachedInfoOverridden. Clears the image source's cached data.  
Protected MethodGetDescriptionPairsOverridden. Get description pairs.  
Protected MethodOnImageDataChangedClears cached data and raises the ImageDataChanged event. (Inherited from Nevron.Nov.Graphics.NImageSource)
