Project Description


I need a developer can make a App using keystone correction, like CamScanner.

Our App is capable of:


- Multi-page document: Scan and manage users documents which can include many pages.

- Quickly batch scanning: Continuous batch scanning and no more wait, fast and convenient.

- Auto-cropping: Auto crop off unnecessary part on an image with keystone correction algorithm.

- Color enhancement: Adjust color and brightness to ultimately make images clear and recognizable automatically.


- Creating PDF: Preview and create PDF files (with note embedded).

- Multiple PDF page sizes: Different sizes of PDF files are available (Letter, A4, B5 and so on.).


- Save images to gallery: Save processed images into gallery.

- Email: Send files (PDF) or processed images via email.

- Cloud storage: Upload & backup files to Google Drive. Restoring it later.


- Add Notes: Every page in a document can be attached a note and searched by them.

- User-defined tags: User-defined tags to be attached to document so as to facilitate management and search.

- Multiple viewing modes: List view and thumbnail view are available.

- Copy/Move: Support copy or move files between documents.

- Search: Quick search documents by title, note or texts within images.

- Merge: Combine multiple documents into one.

(Above requirements are almost same to CamScanner.)

Browse & Download

- The App has browser function that can download pdf and insert the pdf to users library. (can make with UIWebView?)

- URL where the pdf was downloaded is logged to the note.


Conditions of the development

- the developer provides also the source code.

- the developer provides rich comments in the source code so that others can understand.

- the App can work on iPhone (after iPhone4) and iPad (without camera function on 1st iPad).

The development doesn't have to be in a quick pace.
