Added in 1.1.0

public static final @NonNull Bitmap toBitmap(
    @NonNull Drawable receiver,
    @Px int width,
    @Px int height,
    Bitmap.Config config
)

Return a Bitmap representation of this Drawable.

If this instance is a BitmapDrawable and the width, height, and config match, the underlying Bitmap instance will be returned directly. If any of those three properties differ then a new Bitmap is created. For all other Drawable types, a new Bitmap is created.

Parameters
`@Px int width`	Width of the desired bitmap. Defaults to `Drawable.getIntrinsicWidth`.
`@Px int height`	Height of the desired bitmap. Defaults to `Drawable.getIntrinsicHeight`.
`Bitmap.Config config`	Bitmap config of the desired bitmap. Null attempts to use the native config, if any. Defaults to `Config.ARGB_8888` otherwise.

Throws
`kotlin.IllegalArgumentException`	if the underlying drawable is a `BitmapDrawable` where `BitmapDrawable.getBitmap` returns `null` or the drawable cannot otherwise be represented as a bitmap

public static final Bitmap toBitmapOrNull(
    @NonNull Drawable receiver,
    @Px int width,
    @Px int height,
    Bitmap.Config config
)

Returns a Bitmap representation of this Drawable or null if the drawable cannot be represented as a bitmap.

If the result of BitmapDrawable.getBitmap is null or the drawable cannot otherwise be represented as a bitmap, returns null.

Parameters
`@Px int width`	Width of the desired bitmap. Defaults to `Drawable.getIntrinsicWidth`.
`@Px int height`	Height of the desired bitmap. Defaults to `Drawable.getIntrinsicHeight`.
`Bitmap.Config config`	Bitmap config of the desired bitmap. Null attempts to use the native config, if any. Defaults to `Config.ARGB_8888` otherwise.
