Love the package. Great work. I'm not able to get it working with codes generated by the package that are then loaded from my camera roll. I tested the example project in the repo which also failed with a generic decode error.

if let message = try? coder.decode(camImage) {
  messageLabel.text = message
  messageLabel.isHidden = false
  DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
    self.messageLabel.isHidden = true
  }
}

Hi, Do you know if one Android repo exists, like a clone of your project ?

I want to use your code for one project, but i need to have the same with the android app, only to read it

Thanks

I never thought that something that possible to do in Swift. Well done! 👍

Here some ideas to improve performance of your algo:

1. The slowest part of your algo it control point detector. If you will use simplest structure here, you will have better performance and it will be possible to process full image.

  static let lightBackgroundRange = UInt8(0)...UInt8(180) // simple compare better: pixel < 180 
  static let darkBackgroundRange = UInt8(100)...UInt8(255) // simple compare better: pixel > 100 

I recommend to perform threshold separately. Accelerate framework can help

let bit = pixelThreshold.contains(data[x, y]) ? RCBit.one : RCBit.zero

You probably don't need RCBit abstraction. typealias around bool will works better and pretty informative

pixelPatterns[pixelPatterns.count - 1] = lastPattern

This operation call lot of times. Just with change struct to class and you can remove this line

You awesome! =)

Hey,

I would like to know if it possible to increase the number of input characters in the textfield where you put your string with the default configuration. I want to pass firebase UID but I can because they are too long.

Thanks.

Seems like it only works on the output generated image (White Background), not while on a black BG (using the example app). Could this be made configurable?

I tried to apply a CIFilter(name: "CIColorInvert") to the pixelBuffer with not much luck.

Hi!

I know that it isn't issue per se but I have a question directly connected with the code encoder/decoder. May I ask for some data about limitation (especially in terms of character amount) and the "regen" level for damaged codes?

I am trying to decode a Round code with a white tint and black background and an image in the middle. I am running on iOS 14 . Regardless of what scanning mode I put It on, It only works for a dark Roundcode on a white background.

The README states that RoundCodes is written in Swift 5, requires Xcode 11 and is compatible with iOS 13.0+. Does it not work below iOS 13? Which APIs do you use that are not available on, say, iOS 11?
