Methods

Clear()

Resets the current frame buffer to its default starting values (all pixels set to 0).

void Clear()

Clear(Color)

Resets the current frame buffer to with its default starting values set to the specified color.

void Clear(Color color)

Parameters

color Color

The color to use as a default value when clearing the frame buffer.

Fill(Color)

Fill the entire frame buffer using the specified color.

void Fill(Color color)

Parameters

color Color

The color to fill the frame with.

Fill(Point, int, int, Color)

Fill the specific portion of the frame buffer with the specified color.

void Fill(Point start, int width, int height, Color color)

Parameters

start Point

The starting position.

width int

Color GetPixel(Point point)

Parameters

point Point

The position to get the pixel from.

Returns

Color

Color representing the specified pixel.

IsPointWithinFrameBuffer(Point)

Checks if the specified point falls within the area this buffer is covering.

bool IsPointWithinFrameBuffer(Point point)

Parameters

point Point

The point to check.

Returns

bool

True if the point is within this frame's area, otherwise; false.

IsRangeWithinFrameBuffer(Point, Point)

Checks if the specified range of points is within the current frame buffer.

bool IsRangeWithinFrameBuffer(Point start, Point end)

Parameters

start Point

The starting point of the range.

end Point
