Abstract Value Members

abstract def changeSettings(newSettings: Settings): Unit

Changes the settings applied to this canvas.
Changes the settings applied to this canvas.
newSettings
new canvas settings
abstract def clear(buffers: Set[Buffer] = Canvas.Buffer.all): Unit

Clears buffers, such as the backbuffer and keyboard inputs.
Clears buffers, such as the backbuffer and keyboard inputs.
buffers
set of Canvas.Buffers to be cleared
abstract def fill(color: Color): Unit

Fill the surface with a certain color
Fill the surface with a certain color
color
Color to fill the surface with

abstract def getKeyboardInput(): KeyboardInput

Gets the current keyboard input.
Gets the current keyboard input.
returns
current keyboard input
abstract def getPixels(): Vector[Array[Color]]

Returns the pixels from this surface.
Returns the pixels from this surface. This operation can be perfomance intensive, so it might be worthwile to implement this operation on the application code.
returns
color matrix

abstract def getPointerInput(): PointerInput

Gets the current pointer input.
Gets the current pointer input.
returns
current pointer input
abstract def putPixel(x: Int, y: Int, color: Color): Unit

Put a pixel in the surface with a certain color.
Put a pixel in the surface with a certain color.
x
pixel x position
y
pixel y position
color
Color to apply to the pixel

Definition Classes
MutableSurface
abstract def redraw(): Unit

Flips buffers and redraws the screen.
abstract def settings: Settings

The settings applied to this canvas.
abstract def unsafeGetPixel(x: Int, y: Int): Color

Gets the color from the this surface in an unsafe way.
Gets the color from the this surface in an unsafe way.
This operation is unsafe: reading a out of bounds pixel has undefined behavior. You should only use this if the performance of getPixel and getPixels are not acceptable.
x
pixel x position
y
pixel y position
returns
pixel color
