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.

good morning autoit team
please i need your help
am trying to make an program that work with hotkeys
it function is to change the volume to the current application
e.g when i select the vlc window by using this hotkey i will be able to change the vlc volume with out changing the system volume.
am able to get the process handle and the process name of the window
but when am trying to get or set the volume i does not succeded
i tried to search in this forums but no result.
can you please guide me to do that.
am waiting for your answers
thanks in advanced
Hello I wondering how to read more complicated text from image with Tesseract or other method.
I used this script and it works with simple text on white background
I need to read text which looks like this
What I need to do?
Download fonts or something from there https://github.com/tesseract-ocr/tesseract
gimme some info please
I have a situation where I am repeatedly capturing a region of the screen and feeding it into Tesseract OCR. Since the OCR is a relatively slow operation, I would like to create an in memory cache of the ocr results. An ideal hash key for this cache would be a checksum of the captured image. With this I could capture the region, checksum it, and then only if I don't get a cache hit I would write the image out to disk for external OCR.
Now I know I can do this by saving the captured image out to disk, and then summing the disk file with _Crypt_HashFile(). But that's still slower than I would like, and it shouldn't be necessary. Ideally, it should be possible to checksum the image data directly in memory so I don't have to go to disk at all. In order to do that, I need a way to dump a representation of the image into a string (or some equivalent). Then I could use the _Crypt_HashData() function against that string to create my cache hash key.
Googling around I found an article here that shows a way to convert an image object to a byte array using System.Drawing. This was the closest thing I found to what I'm trying to do. I don't know if that method could be used from within AutoIT, or if perhaps there may be a better way I don't know about. If someone could give me a shove in the right direction it would be a big help. Thanks!
I found this function in the Internet
It is to play audio files from the compiled script
I did not understand just one thing on this function
func play($name, $wait = 0) local Const $SND_RESOURCE = 0x00040004 local Const $SND_ASYNC = 1 ; Play the file - the script will pause as it sounds if $wait = 0 then DllCall("winmm.dll", "int", "PlaySound", "str", $name, "hwnd", 0, "int", BitOR($SND_RESOURCE, $SND_ASYNC)) else DllCall("winmm.dll", "int", "PlaySound", "str", $name, "hwnd", 0, "int", $SND_RESOURCE) endIf return 1 endFunc What I did not understand was this variable
local Const $SND_RESOURCE = 0x00040004 I know that this variable is contains the resource name
But what if I want to change the name of the resource what i'll do?
can i do that?
Thanks in advance
