BitmapKt

public static final @NonNull Bitmap applyCanvas(
    @NonNull Bitmap receiver,
    @ExtensionFunctionType @NonNull Function1<@NonNull Canvas, Unit> block
)

Creates a new Canvas to draw on this bitmap and executes the specified block on the newly created canvas. Example:

return Bitmap.createBitmap(…).applyCanvas {
   drawLine(…)
   translate(…)
   drawRect(…)
}

public static final boolean contains(@NonNull Bitmap receiver, @NonNull Point p)

Returns true if the specified point is inside the bitmap. A point is contained if: 0 <= x < width and 0 <= y < height. An empty bitmap never contains any point.

public static final boolean contains(@NonNull Bitmap receiver, @NonNull PointF p)

Returns true if the specified point is inside the bitmap. A point is contained if: 0 <= x < width and 0 <= y < height. An empty bitmap never contains any point.

public static final @NonNull Bitmap createBitmap(int width, int height, @NonNull Bitmap.Config config)

Returns a mutable bitmap with the specified width and height. A config can be optionally specified. If not, the default config is Bitmap.Config.ARGB_8888.

@RequiresApi(value = 26)
public static final @NonNull Bitmap createBitmap(
    int width,
    int height,
    @NonNull Bitmap.Config config,
    boolean hasAlpha,
    @NonNull ColorSpace colorSpace
)

Returns a mutable bitmap with the specified width and height. The config, transparency and color space can optionally be specified. They respectively default to Bitmap.Config.ARGB_8888, true and sRGB.

public static final int get(@NonNull Bitmap receiver, int x, int y)

Returns the value of the pixel at the specified location. The returned value is a color int in the sRGB color space.

public static final @NonNull Bitmap scale(@NonNull Bitmap receiver, int width, int height, boolean filter)

Creates a new bitmap, scaled from this bitmap, when possible. If the specified width and height are the same as the current width and height of this bitmap, this bitmap is returned and no new bitmap is created.

public static final void set(@NonNull Bitmap receiver, int x, int y, @ColorInt int color)

Writes the specified color int into the bitmap (assuming it is mutable) at the specified (x, y) coordinate. The specified color is converted from sRGB to the bitmap's color space if needed.
