Note: slash at beginning of saveAs filename, full path given for objectLocation, and fileType = JPG not jpg

I had already tried both JPG and jpg.
Looks like the path may be the issue, ill try later and update on results.

Is these extension support marathi language?

17

Check if the language is listed here.

Hi @gopal_gopal
I searched on Free OCR API and on language I did not find reference to marathi language.
But if You use ocrEngine 3 with OCRFromFile You can use:
Hindi = hin
Kannada = kan
Telugu = tel
Tamil = tam
I hope this can be useful this for You?

Marco

Hi Marco,
I'm trying to use your extension for receipt recognition and it works!
But unfortunately you didn't include in the OCRFromFile call two important parameters that are present in the OCR API and could drastically improve the OCR quality: IsTable and DetectOrientation.
Is it possible to add these parameters?
Thank you
Alex

Hi Alexandre,
in the next few days I will check and try to add these parameters.
Best Regards
Marco

Grazie mille Marco!

Ciao a tutti,

ocrFromFile
I added two parameters

isTable can be true or false
detectOrientation can be true or false

OCRAPI here You can find when to use it

OCRSpace.aix (18.3 KB)
OCR.aia (23.6 KB)

Best Regards

Hi @Hikari did You follow the instruction at the beginning.
Register to have your api key, and then add your api key in the OCRKey variable in the project
I think this is your problem.

$r = $client->request('POST', 'http://api.ocr.space/parse/image',[
'headers' => ['apiKey' => 'KEY', 'OCREngine'=> 2 ],
'multipart' => [
[
'name' => 'file',
'contents' => $fileData

        ]
    ]
], ['file' => $fileData],  ['OCREngine'=> 4 ] );
$response =  json_decode($r->getBody(),true);

Please help me to put correctly OCREngine

Does anyone use the paid API?
I'm testing the extension using free API. The extension seems to work fine, but the free API is unavailable all the time. Does the paid version have the same problem?

Starting today with app inventor, just imported the ocr.space extension but what should I put for the first block: "For component"?

30

you are using 'any component', try use a specific one.

drag blocks from 1, not 2
