Lib JAVA or ColdFusion, reading of questionnaires, OCR

I need an android app to We need a java lib to be developed, for OCR processing of PDF files of questionnaires.

Processing should:

- check the orientation of the file, rotating it 90 or 180 degrees if necessary

- adjust the orientation of the file, if the file is not correctly aligned, the API must correct the files, up to 30 degrees of distortion

- for processing, the API must convert the file to Black and White, with a configurable value, which must be defined in the constructor in the API.

- the processing must generate a second file with the markings of the items that were located and marking with rectangles the information read in the file.

About the Archive:

- The file has a QRcode and 3 squares in its corners, which serve to signal the API if the file is complete, being also used for file alignment.

- Footer, OCR reading the string between the two footer squares

- About the questions:

- The number and type of questions can be varied, the API must adapt to different file configurations.

- we can have two types of questions

- Multiple choice

- in this type we can have 0 to N marked responses.

- Dissertation

- In this type the API must end its area to return an image with the clipping of this question.
