Hi

We used the following example code in order to get a searchable PDF (Aspose OCR Version 22.11.0):

List<RecognitionResult> res = api.RecognizePdf("test8.pdf", new DocumentRecognitionSettings(0, 2)
        {
            Language = Language.None
            //AutoContrast = true
        });
        AsposeOcr.SaveMultipageDocument("result8.pdf", SaveFormat.Pdf, res);

About 50% is recognized, and it shows a wrong position for the searched text.

1.pdf (145.5 KB)
2.pdf (148.6 KB)

The properties with Contrast and language are also not working properly.
With AutoContrast the original document gets very bright and is almost ruined.
result3.pdf (118.7 KB)

For a concrete document in german we get with the value Language.Deu only 20% text.

can we optimize here something in order to get the right position and get more recognized text?

thanks in advance for an answer
