getBitmap
public Bitmap getBitmap()
getPixel
public Color getPixel(float x,
float y)
- Gets the color at location (x,y) in the texture. The lookup is performed
using the fractional component of the coordinates, treating the texture
as a unit square tiled in both directions. Bicubic filtering is performed
on the four nearest pixels to the lookup point.
- Parameters:
x
- x coordinate into the texturey
- y coordinate into the texture
- Returns:
- filtered color at location (x,y)
