按代码截取iOS设备的屏幕截图（不是swift或xamarin）

Question

I'm working on verifying screen of the iOS app by using tesseract engine (OCR). I'm using Ranorex (Test automation tool) that use .net 4.5 frame.

MobileApp targetApp = repo.App;
    Bitmap actualImage = Imaging.CaptureImage(targetApp,0,true);

I used above code to get a bitmap of the current screen. However, the resolution is too low to run OCR. Therefore, I need to work on the other ways.

1st: If Ranorex has some function that takes high resolution of the screen image.

2nd: If there is c#(.net frame 4.5) code that can get high resolution of the screen image.

3rd: Find a tool to take a screen shot of iPad app (external tool), and save all high resolution screen shot first, and read the file by bitmap(C:\\xxxx).

It would be great if I can get a good suggestion.

Thank you for helping me.

You can take screenshots using the UIAutomation framework from Apple.

You can use this code to generate screen shots:

target.captureScreenWithName("HomeScreen");
