[UIImage g8_grayScale]: unrecognized selector sent to instance 0x1c00ad860'

[Rufy86]

I've reproduced the app WhichFont using Tesseract Without CocoaPods. The problem is it goes in crash in CameraViewControler File

if let rec = recognition { switch rec { case .grayscale: img = img.g8_grayScale() //<-- here goes in crash an there is a warning that say this method is deprecated case .blackwhite: img = img.g8_blackAndWhite() //here too } }

how Can I fix it?

For first you can look into this page https://www.raywenderlich.com/93276/implementing-tesseract-ocr-ios Also, those methods are removed so you can use GPUImage that is more fast.

Thank you for the reference, but I need to see how it work and if work, before to read other documentation. raywenderlich it's great but old. So, when can you fix this bug?

(Grazie mille per la documentazione, ma vorrei prima vedere come funzione e , soprattutto, se funziona la tua app e l'integrazione tra Vision di Apple e Tesseract, prima di leggere altra documentazione. Perciò, quando avrai modo di correggere il bug?)

Thank you

Why do you hate cocoapods? :)

You can replace the img.g8_grayScale() method with https://github.com/gali8/Tesseract-OCR-iOS/wiki/Tips-for-Improving-OCR-Results#using-gpuimages-adaptive-threshold-filter

I hate cocoa pods because insert files without control. but now I've installed cocoapods and I don't know why this method work without problem. maybe is because you create the framework, this don't contains some headers that I find in the framework made by cocoaPods.

Yep => gali8/Tesseract-OCR-iOS#225

[Rufy86]

however, please make a version or a way to use updated tesseract without cocoapods, thanks
