Tesseract-OCR not recognising single characters

[ianfj...@yahoo.com]

Hi people, I have a bit of a problem with Tesseract-OCR 3.02.02. (installed with .exe version)

My project in Visual Studio 2013 using Visual Basic Windows Form it is supposed to scan an area of the screen and save the image as a .png then Tesseract is supposed to take that file and do its voodoo and save the result to a text file. Well, it seemed to be working until I discovered that it would only convert double digits (10, 15, 35 etc.) to text, single digits of 0 to 9 are not (all digits are of the same size) , the same goes for letters, I tried the letter T it was a no go, as soon as I tried TT there it was in the text file.

Now I've just spent the entire week trying to find easy to read info on this, half of what I've read comes across to me as a relative newbie as Martian, so any advice would be most appreciated if it is couched in "Janet and John" terms or words of two syllables or less and with as much detail as possible, it took me quite a while to cobble together what code I have after a lot of trial and error, here it is below.

Imports System

Imports System.IO

Imports System.Text

Imports System.Collections

Imports Microsoft.VisualBasic

Public Class Form1

Dim a, b

Dim myStack As New Stack()

Private Sub Button1_Move(ByVal sender As System.Object, ByVal e As EventArgs) Handles Button1.Move

Call shoot()

End Sub

Private Sub shoot()

Form2.Show()

Dim area As Rectangle

Dim capture As System.Drawing.Bitmap

Dim graph As Graphics

area = Form2.Bounds

capture = New System.Drawing.Bitmap(area.Width, area.Height, System.Drawing.Imaging.PixelFormat.Format32bppRgb)

graph = Graphics.FromImage(capture)

a = 513

b = 144

graph.CopyFromScreen(area.X + a, area.Y + b, 0, 0, area.Size, CopyPixelOperation.SourceCopy)

PictureBox1.Image = capture

Try

PictureBox1.Image.Save("C:\Tesseract-OCR\Last-Result.bmp")

System.Diagnostics.Process.Start("C:\Tesseract-OCR\tesseract.exe/-psm 10", "C:\Tesseract-OCR\Last-Result.bmp C:\Tesseract-OCR\Variable-Number")

Catch ex As Exception

End Try

End Sub

End Class

I have also included two of the images that I'm experimenting with at the moment to illusatrate that the numbers are of the same size and quality.

Many thanks for any help given in helping me fix this. 

(P.S. Someone really needs to write a book "Tesseract-OCR for dummies".....with pictures......I'd buy it lol)
