hi , can any one tell me wich scanner provides BMP pictures with 300 DPI resolutin or how do we
get it because I have a problem in reading the image because of the resolution may be…
the second trouble that aspose Confuses the worlds , it did not read the content of the image
Sequentially , I will put an example the image (bmp) the code source the result
is the problem because of the table !! because the data are in a table !!
the in put pic !!
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());
}
//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());
}

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.
