Canvas Paint text size android -

-

i have mutable bitmap , i'm drawing on canvas. after want draw pre-defined text on bitmap. problem have different bitmap sizes, though i'm setting text size 20sp, depending on bitmap size text bigger of smaller, want text size same images. should do? thought of maybe scaling text size depending on image width , weight i'm not sure how that. 

final bitmap mutablebitmap = bitmap.copy(bitmap.config.argb_8888, true); final canvas canvas = new canvas(mutablebitmap); final paint paint = new paint(); paint.settextsize(getresources().getdimensionpixelsize(r.dimen.myfontsize); canvas.drawtext(text, x, y, paint);

first of if ondraw method doing wrong work here. shouldn't allocate inside ondraw method. on other hand , shouldn't change text size bitmaps. resize bitmaps on same values(width , height) , setting text same value.

disclaimer: know other people on site have had error it's been in different contexts , fixes don't seem work here. hey stackoverflow, i've been making sideways space invaders game, ship follows mouse's y position stays on left, , clicking shoots bullet. enemies spawn randomly right , fly left, , objects removed once each side of screen. works fine, when tried implement collision detection see when shot hits enemy, error: typeerror: argument must rect style object. it points line "return hitbox.colliderect(target.rect)". try , work out causing made 'print' lines below see 'target.rect' (and whether proper rect object), , seemed same style shot's own rect, i'm lost why colliderect doesn't accept it. i've annotated pretty everything, sorry if it's insult intelligence should make things easier. class causes problems: class gameobject: def __init__(self, image, height, speed): self.speed = speed self.image...

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...
