How to get skew angle from image

Question

I am facing problem to get the skew angle from image .I am using tesseract api for image processing. I have searched a lot on web but no appropriate solution found. I have used following code:

Pix test=ReadFile.readBitmap(bitmap.createBitmap(400, 400, Config.ARGB_8888));
float angle=Skew.findSkew(test);

from above code I get angle value 0.0. Please help me to resolve this problem or show the right direction to resolve this problem.

Answer 1

 public static float findSkew(Pix pixs, float sweepRange, 
                              float sweepDelta, int sweepReduction,
                              int searchReduction, float searchMinDelta)

Your findSkew(...) does not have the correct parameters.

Answer 2

TessBaseAPI baseApi = new TessBaseAPI();
baseApi.setImage(bitmap);    
Pix test = baseApi.getThresholdedImage();
float a = Skew.findSkew(test);

Sometimes get 0.0, generally work. But I'm not sure of the correct.
