Thank you for writing us back.
This is to update you that Aspose.OCR APIs currently supports Arial, Times New Roman, Courier New, Tahoma, Calibri and Verdana in Regular, Bold and Italic styles with black text color and white background. Images with colorful background are not supported. Please note that the current implementation of the Aspose.OCR APIs perform well with images having resolution of at least 300 DPI and the accuracy rate tends to decrease by decreasing the resolution.
