   row ,
   lines 
)

public:
void ValidateLines( 
   int row,
   int lines
) 

Parameters

row

Row number of the first line in the image to validate. In the RasterCodecs.LoadImage event, this corresponds to the first line in the buffer.

lines

Number of lines to validate. In the RasterCodecs.LoadImage event, this corresponds to the number of lines in the buffer.

The Append method enables you to update an image in the RasterCodecs.LoadImage event, so that you can play an animation file as it is being loaded. The ValidateLines method lets you validate the lines that the animation playback engine will render to the target image.

If you pass null (Nothing in VisualBasic) in the animatedImage parameter for the RasterImageAnimator constructor, you can use the Append method to add frames to the multi-frame image during the animation. This is useful if you want to play an animated file as it is being loaded. If you need to reference the multi-frame image after the animation, you can call the Destroy method before you dispose this RasterImageAnimator object.

After you call Destroy, this RasterImageAnimator object is invalid and you should only call the Dispose method afterwards.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
