Attributes
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
-

- Definition Classes
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.
Value parameters
- x
-
pixel x position
- y
-
pixel y position
Attributes
- Returns
-
pixel color
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.
Value parameters
- x
-
pixel x position
- y
-
pixel y position

- Returns
-

Gets the current keyboard input.
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.
