Abstract methods
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
Puts a pixel in the surface in an unsafe way.
Puts a pixel in the surface in an unsafe way.
This operation is unsafe: writing a out of bounds pixel has undefined behavior.
You should only use this if the performance of putPixel
is not acceptable.
Attributes
- x
pixel x position
- y
pixel y position
- Returns:
pixel color
Concrete methods
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
Fill the whole surface with a certain color.
Fill the whole surface with a certain color.
Attributes
- color
Color

Inherited methods
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

- Returns:
pixel color
- Inherited from:
- Surface
Gets the color from the this surface, falling back to a default color when out of bounds.
Similar to getPixel(x, y).getOrElse(fallback)
, but avoids an allocation.

Attributes
- fallback
fallback color
- x

- y
pixel y position
- Returns:
pixel color

Attributes
- Returns:
color matrix
- Inherited from:
- Surface
Copies this surface into a new surface stored in RAM.
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 from:
- Surface
Returns a view over this surface.
Returns a view over this surface.
Operations performed on a view are executed in a defered fashion.
