clear

abstract fun clear()

Remove all Bitmaps from this pool and free their memory.

get

abstract fun get(@Px() width: Int, @Px() height: Int, config: Bitmap.Config): Bitmap

Return a Bitmap of exactly the given width, height, and configuration, and containing only transparent pixels.

getDirty

abstract fun getDirty(@Px() width: Int, @Px() height: Int, config: Bitmap.Config): Bitmap

Identical to get except that any returned Bitmap may not have been erased and may contain random data.

getDirtyOrNull

abstract fun getDirtyOrNull(@Px() width: Int, @Px() height: Int, config: Bitmap.Config): Bitmap?

Identical to getDirty except that null will be returned if the pool does not contain a usable bitmap.

getOrNull

abstract fun getOrNull(@Px() width: Int, @Px() height: Int, config: Bitmap.Config): Bitmap?

Identical to get except that null will be returned if the pool does not contain a usable bitmap.

put

abstract fun put(bitmap: Bitmap)

Add the given Bitmap to the pool if it is eligible to be re-used and the pool can fit it.

trimMemory

abstract fun trimMemory(level: Int)
