c# - WPF spritesheet animation -


i trying create animated sprite spritesheet in wpf. current technique using breaking down image of containing frames of animation separate images , swapping them out.

however costly on memory , wondering if there way draw section of image (specify source rectangle) rather splitting image up.

you can this. in order supported wpf's built-in animation system need animate dependency property. in case seems want animate sourcerect property of croppedbitmap using rectanimationusingkeyframes discreterectkeyframe class.

if you're displaying image using image element set it's source property croppedbitmap, cropped bitmap have source property set bitmapimage. cropped bitmap wraps standard bitmap , adds cropping functionality.
