Gets or sets a value indicating which frame, if any, the destination bitmap already contains.
public int PriorFrame { get; set; }Property Value
Remarks
Only meaningful for multi-frame images.
If FrameIndex needs to be blended with a prior
frame (as reported by SKCodec.FrameInfo[FrameIndex].RequiredFrame), the
client can set this to any non-RestorePrevious
frame in the range [RequiredFrame, FrameIndex) to indicate that that frame is
already in the destination. ZeroInitialized is
ignored in this case.
If set to -1, the codec will decode any necessary required frame(s) first.
