Please, ensure your title is less than 63 characters long and starts with a capital letter.

Which platform(s) does your issue occur on?

  • iOS
  • emulator and device.

Is there any code involved?

I think this code snippet or something similar should do the job.

if (args[1] instanceof Matrix) { CGContextConcatCTM(ctx, args[1]._transform); CGContextTranslateCTM(ctx, 0, image.size.height); CGContextScaleCTM(ctx, 1.0, -1.0); CGContextDrawImage(ctx, CGRectMake(0, 0, image.size.width, image.size.height), image.CGImage); return; }

I wanted to create a pull request but I didn't know how to. I just tried to modify the canvas.ios.js code in my project's node_modules folder and it worked. @farfromrefug Can you please check it? It is urgent for my project to finish.

@stemyke should be working in 4.0.46 (in drawBitmap not drawImage !)

@farfromrefug You are right, I wrote the issue in a hurry, but thanks for quick response :)
