Concrete methods

override def fill(color: Color): Unit

Fill the whole surface with a certain color.

Fill the whole surface with a certain color.

Attributes

color

Color to fill the surface with

Definition Classes
MutableSurface
def fillRegion(x: Int, y: Int, w: Int, h: Int, color: Color): Unit

Fill part of the surface with a certain color.

Fill part of the surface with a certain color.

Attributes

color

Color to fill the surface with

h

region height

w

region width

x

leftmost pixel on the destination surface

y

topmost pixel on the destination surface

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.

Attributes

color

Color to apply to the pixel

x

pixel x position

y

pixel y position

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.

Attributes

x

pixel x position

y

pixel y position

Returns:

pixel color

Inherited methods

def blit(that: Surface, mask: Option[Color])(x: Int, y: Int, cx: Int, cy: Int, cw: Int, ch: Int): Unit

Draws a surface on top of this surface.

Draws a surface on top of this surface.

Attributes

ch

clip height of the source surface

cw

clip width of the source surface

cx

leftmost pixel on the source surface

cy

topmost pixel on the source surface

mask

color to use as a mask (pixels with this color won't be merged)

that

surface to draw

x

leftmost pixel on the destination surface

y

topmost pixel on the destination surface

MutableSurface
def getPixel(x: Int, y: Int): Option[Color]

Gets the color from the this surface. This operation can be perfomance intensive, so it might be worthwile to either use getPixels to fetch multiple pixels at the same time or to implement this operation on the application code.

Attributes

x

pixel x position

y

def getPixels(): Vector[Array[Color]]

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.

Attributes

Returns:

final def toRamSurface(): RamSurface

Copies this surface into a new surface stored in RAM.

Copies this surface into a new surface stored in RAM.

Attributes

Inherited from:

def view: SurfaceView

Returns a view over this surface.

Returns a view over this surface.

Operations performed on a view are executed in a defered fashion.
