Obtaining cropped,unskewed AND uncropped raw image when using BlinkID iOS SDK

Question

I'm trying to capture ID scan using MicroBlink BlinkID library I need to get both:

1. processed , cropped unskewed image from front and back of the ID
2. unprocessed raw UIImage of which front picture was processed out.

returnFullDocumentImage and encodeFullDocumentImage but I'm always getting cropped images accessing those properties:

fullDocumentFrontImage?.image

fullDocumentBackImage?.image

how to get uncropped front image of the ID?

whatever I do, I get nil when trying to access: frontCameraFrame?.image

Answer 1

Found it

I needed to set

blinkIdCombinedRecognizer.saveCameraFrames = true

Answer 2

Yes, that’s correct! By setting saveCameraFrame to true, you can obtain frontCameraFrame, backCameraFrame, and barcodeCameraFrame.

Also, if you want to extract the face image or the signature from the document, you can do that:

self.blinkIdRecognizer?.result.faceImage
self.blinkIdRecognizer?.result.signatureImage
