Need reworking on code, poor image quality on output and missing source code #152

Open fpiraneo opened 3 years ago

fpiraneo commented 3 years ago

This library is potentially cool but now quite outdated and need a reworking on many parts; many parts of code use deprecated functions; has issues when running on new Android versions due to permissions; the maximum image resolution on output is always 1024 x 768 and cannot be increased. Finally the sources of two libraries that are provided pre-compiled are missing; why? I think that the issues are there!

To all people: PLEASE help me to find a replacement solution or the sources of the precompiled libraries. Thanks!

I'm using the following library and it is working for me. AndroidDocumentScanner

Only issue that i'm facing with https://github.com/mayuce/AndroidDocumentScanner library is app size increases by 30 MB. Is it the same 30 MB app size increase with the library you are using ?

Talking about only the pre-compiled opencv and (I think) the image processing libraries that jansireddy provide pre-compiled, for all platform the folder last about 74Mb that must be uploaded on the Android Store. Then I have all my application.

Taking a look at the mayuce lib you suggested me, we have the strong value that is 100% open with no pre-compiled parts and the full arm64 compiled version is just 11.2Mb!
