Leptonica throws error:

findFileFormatStream: failed to read first 12 bytes of file

Something has changed in new update. Cropping itself seems to be working...

Hi,

I really like the potential of this app, and would like it even more if I could have it in my native language. I took a look at the .ts file and found that it is far from complete. Are you planning to update translation file and implement localisation? If so, I would be the first to translate.
Great job anyway. Thanks!

Due to Google code shutdown Tesseract OCR codebase along other data was moved to GitHub. The data will be archived to Google Code archive, but it will be more future proof to refactor the language data downloading so that it will fetch the data from GitHub according to the release of Tesseract.

3.04 contains already a set of new language data files and Textractor still uses the 3.02 version files.

Todo:

• figure out the easiest way to download the .traineddata files from GitHub: https://github.com/tesseract-ocr/tessdata
• refactor codebase to support this new method

If the phone is laying flat (camera pointing down) it is pretty much impossible to detect (or to know/guess) the correct orientation for the image. Solution is to add button to camera page which makes it able to toggle manual lock on different orientations.

Stuff needed: icon for all 4 orientations.

Currently Textractor overwrites the old preprocessed image when new recognition is run. Do we need to save all the results or is it enough to see the latest preprocessed image?

It might be possible that Tesseract leaks memory if the recognition is canceled. If this is the case, cancel function will not be implemented.

Following icons are missing:

• icon-camera-automatic
• graphics-cover-camera

Fix: try to find icon which exists on SFOS 2.0 and in earlier systems too.

Is it possible to completely skip the image processing? Send the image directly to tesseract?

Thank you for your work,
Cosmin Popescu.

Allow user to crop the image before processing.

Settings page contains complex parameters. Write guide how to adjust them.

Additionally split the settings page to advanced and basic settings.

Textractor interferes with Jolla's camera app sometimes because the camera is not always unloaded properly in this situation.

Currently the camera is not unloaded and this makes the app consume too much power if user pushes the app to the background after recognition.

If user tries to process an image which was taken with Jolla's camera app and the orientation was not standard, image will appear in wrong orientation after preprocessing since afaik Jolla's camera app only adds exif orientation information and does not actually rotate the image and seems that Leptonica does not support exif data.

Fix: find a way to read the exif data and rotate the image before preprocessing.

Currently only jpeg is confirmed to be working. This may need changes to Leptonica spec file to be able to build it with additional image formats.

Scanners often create pdf-documents when you use them for copying. It would be real handy if the text in those pdfs would be available.
