OCRSpace UDF

AutoIT-OCRSpace-UDF1.3.zip

This tiny yet powerful UDF will help you to convert Images to text with the help of  OCRSpace API version 3.50 .

Detect text from a local file.

; =========================================================
; Example 2 : Gets text from an image from a local path reference
;           : Searchable PDF is not requested by default.
;           : Processes it using a basic OCR logic.
; =========================================================

$b_Create_Searchable_PDF = True

; Use a table logic for receipt OCR
$b_Table = True

; Set your key here.
$v_OCRSpaceAPIKey = ""

$OCROptions = _OCRSpace_SetUpOCR($v_OCRSpaceAPIKey, 1, $b_Table, True, "eng", True, Default, Default, $b_Create_Searchable_PDF)
$sText_Detected = _OCRSpace_ImageGetText($OCROptions, @scriptdir & "\receipt.jpg", 0, "SEARCHABLE_URL")

ConsoleWrite( _
        " Detected text   : " & $sText_Detected & @CRLF & _
        " Error Returned  : " & @error & @CRLF & _
        " PDF URL         : " & Eval("SEARCHABLE_URL") & @CRLF)

 

Detect text from a URL reference.

; =========================================================
; Example 1 : Gets text from an image using a url reference
;           : Searchable PDF is not requested.
;           : Processes it using a basic OCR logic.
; =========================================================

$v_OCRSpaceAPIKey = ""

; SetUp some preferences..
$OCROptions = _OCRSpace_SetUpOCR($v_OCRSpaceAPIKey, 1, False, True, "eng", True, Default, Default, False)
; Make the request..
$sText_Detected = _OCRSpace_ImageGetText($OCROptions, "https://i.imgur.com/vbYXwJm.png", 0)

ConsoleWrite( _
        " Detected text   : " & $sText_Detected & @CRLF & _
        " Error Returned  : " & @error & @CRLF)

 

Detect text from a URL reference to an array

#include "OCRSpaceUDF\_OCRSpace_UDF.au3"
#include <array.au3>

; Set your key here.
$v_OCRSpaceAPIKey = ""
    
$OCROptions = _OCRSpace_SetUpOCR($v_OCRSpaceAPIKey, 1, $b_Table, True, "eng", True, Default, Default, False)
    
; Below, the return type is set to 1 to return an array containing the coordinates of the bounding boxes for each word detected,
; in the format : #WordDetected , #Left , #Top , 3Height, #Width
    
$aText_Detected = _OCRSpace_ImageGetText($OCROptions, "https://i.imgur.com/Z1enogD.jpeg", 1)

_ArrayDisplay($aText_Detected, "")

hi, thank you for this! I have had problems with accuracy with Tesseract (specifically numbers). I found this to be more reliable. Although sometimes it works better with Engine 1, sometimes Engine 2.

Also, sometimes I get what I assume to be a timeout message. Any idea on how to handle this:

"C:\Program Files (x86)\AutoIt3\Include\_OCRSpace_UDF.au3" (508) : ==> Unknown function name.:
If Not _WinAPI_IsInternetConnected() Then
If Not ^ ERROR

Hi,

Please make sure you read the  OCRSpace API link before you get too involved in this UDF. This is NOT a stand-alone OCR solution and requires internet linkage to the host server with various limits on frequency and size for the free subscription. I do not want to put anyone off, but this is not clear from the OP.

Yes. I have the free account. I am far from the daily/monthly limit testing. So the error is not because of that…

You're welcome and thanks too for feedback !

_WinAPI_IsInternetConnected() is declared in  WinAPIDiag.au3. My bad, I forgot to include it in the udf. You can include it in your script or in the OCRSpace UDF by :

#include <WinAPIDiag.au3>

Too much Error and Warning. And I'm not sure about this test 😐
