DirtyRects

Gets or sets list of updated rectangles that you update in the back buffer for the presented frame. An application must update every single pixel in each rectangle that it reports to the runtime; the application cannot assume that the pixels are saved from the previous frame.

Declaration
public nint DirtyRects { get; set; }
Property Value
Type Description
nint

DirtyRectsCount

Gets or sets the number of updated rectangles that you update in the back buffer for the presented frame. The operating system uses this information to optimize presentation. You can set this member to 0 to indicate that you update the whole frame.

Declaration
public uint DirtyRectsCount { get; set; }
Property Value
Type Description
uint

ScrollOffset

Gets or sets the offset of the scrolled area that goes from the source rectangle (of previous frame) to the destination rectangle (of current frame).

Declaration
public nint ScrollOffset { get; set; }
Property Value
Type Description
nint

ScrollRect

Gets or sets the scrolled rectangle. The scrolled rectangle is the rectangle of the previous frame from which the runtime bit-block transfers content. The runtime also uses the scrolled rectangle to optimize presentation in terminal server and indirect display scenarios.

Declaration
public nint ScrollRect { get; set; }
Property Value
Type Description
nint
