c# - How to shrink image to disappear gradually in WPF DoubleAnimation -

-

so, i'm making application , want gradually (over course of few seconds) shrink image control until disappears. so, bound scaletransform doubleanimation, happens instantly. here code:

doubleanimation anim = new doubleanimation(360, 0, (duration)timespan.fromseconds(1)); scaletransform st = new scaletransform();  st.scalex = 0; st.scaley = 0; pacscore.rendertransform = st; anim.completed += (s, _) => exit_pacs(); st.beginanimation(scaletransform.scaleyproperty, anim);

this should trick:

doubleanimation anim = new doubleanimation(1, 0,(duration)timespan.fromseconds(1));  scaletransform st = new scaletransform(); control.rendertransform = st; st.beginanimation(scaletransform.scalexproperty, anim); st.beginanimation(scaletransform.scaleyproperty, anim);

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
