ios - How to find the colour of an individual pixel in UIImage in swift -


i have following swift code.

let resolution = [imageview.frame.size.width, imageview.frame.size.height]  x in 0...int(resolution[0]) {     y in 0...int(resolution[1]) {         let coordinate = [x, y]         //find colour of pixel here     } }

i want able find colour being displayed each individual pixel in photo. there way modify code have put "//find colour of pixel here" print rgb value of pixel @ coordinate represented constant coordinate?

you can try following:

var pixel : [uint8] = [0, 0, 0, 0] var colorspace = cgcolorspacecreatedevicergb() let bitmapinfo = cgbitmapinfo(cgimagealphainfo.premultipliedlast.rawvalue) let context = cgbitmapcontextcreate(unsafemutablepointer(pixel), 1, 1, 8, 4, colorspace, bitmapinfo)

hope helps!!

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
