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.

Start by reading the drawImage path in canvas.ios.js and compare it with the Matrix snippet in the issue. Test the behavior on both the iOS emulator and device; it is done when drawImage calls using a Matrix render the image with the requested transform.
