Hi khecha,

Thank you for your inquiry.

Please note that scanners have application interface and through that interface you can set the scanning preferences. You can set that scanned image should be of 300 DPI or 600 DPI and so on up to the extent that is supported by the hardware. Furthermore you can specify/select the type of output image.

We have evaluated the image sample provided by you. Following is the code snippet for your reference. It is working fine. Generated output is also given below.

String imagePath = "G:\\Input\\z.png";
//Initialize an instance of OcrEngine
OcrEngine ocrEngine = new OcrEngine();
//Set the Image property by loading the image from file path location
ocrEngine.setImage(ImageStream.fromFile(imagePath));
//Process the image
if (ocrEngine.process())
{
//Display the recognized text
System.out.println(ocrEngine.getText());
}

OUTPUT:
S CoFAC C-DEP C-TEST C-MOD CoaRAD C-OPT CoETUD NoED
25 2 ENPP 1 E POC M1 GL .10/4030044.20
1234567890257

Hope the above information helps. Feel free to contact us in case you have further query or comments.

Hi khecha,

Please note that we have evaluated the attached image at our end. While testing it was found that the image has very low DPI value i.e. 96. Please note that the current implementation of the Aspose.OCR API works well with images having resolution of at least 300 DPI and the accuracy rate tends to decrease by decreasing the resolution. Your provided image has resolution of 96 DPI therefore it will not be possible to get 100% accuracy.
