Tesseract Simple Example

[JohnOne]

There has been many questions about using tesseract of late.

Here is a very basic example which works for me, along with the exact version of standalone tesseract executable and English language data used

I found it some time ago at a time I thought I needed it, I do not recall from where.

$ImageToReadPath = @ScriptDir & "\image.bmp"
$ResultTextPath = @ScriptDir & "\Result"
$OutPutPath = $ResultTextPath & ".txt"
$TesseractExePath = @ScriptDir & "\Tesseract.exe"

ShellExecuteWait($TesseractExePath, '"' & $ImageToReadPath & '" "' & $ResultTextPath & '"', "", "", @SW_HIDE)

If @error Then
    Exit MsgBox(0, "Error", @error)
EndIf

MsgBox(0, "Result", FileRead($OutPutPath))

FileDelete($OutPutPath)

Some Answers:

The files contained in the download, only support English language.

From the only documentation I got with this version...

Original Binaries and Source can be found here:
http://code.google.com/p/tesseract-ocr/

I do not know where to get other languages support.

I do not know if there is a later standalone version.

I do not know why it does not read your image accurately.

It does not have a virus in it.

You can search the forums or internet to learn how to create / cut / copy / paste, or otherwise manipulate your own images.

Just seen this post which might be relevant

You can download the latest windows installer from this link:

http://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-setup-3.05.00dev.exe

It includes also many languages.

No idea what that URL is.

I'd advise anyone looking for tesseract to get it from official GitHub.

https://github.com/tesseract-ocr/tesseract/wiki

That URL is.... exactly from the Github page you refer to.

https://github.com/tesseract-ocr/tesseract/wiki/Downloads

Under "3rd party Windows exe's/installer"

The URL is from a German Univercity i guess.

I tested it with your Autoit script but changed the Filepath to the install path.

Works perfectly.

Thanks for that.

I see, thanks for clearing that up.

Just another simple example for using tesseract with an image file:

#Include <File.au3>
#include <WindowsConstants.au3>

Local $img_filename = FileOpenDialog("Image file", @DesktopDir & "\", "Images (*.tif;*.png;*.jpg)", $FD_FILEMUSTEXIST)
$ocr_filename = StringLeft($img_filename, StringLen($img_filename) - 4)
$ocr_filename_and_ext = $ocr_filename & ".txt"

;Double quotation marks are for paths containing spaces (tested on Tesseract V3.02)
Local $iPID = Run(@ComSpec & " /C " & "tesseract.exe """ & $img_filename & """ """ & $ocr_filename & """", @ProgramFilesDir & "\Tesseract-OCR", @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
ProcessWaitClose($iPID)
;This also works:
;ShellExecuteWait(@ProgramFilesDir & "\Tesseract-OCR\tesseract.exe", " """ & $img_filename & """ """ & $ocr_filename & """")

;Display text in SciTe editor
Run(@ProgramFilesDir & "\AutoIt3\SciTE\SciTE.exe """ & $ocr_filename_and_ext & """", "", @SW_SHOWMAXIMIZED)
