OCR Tesseract Image DPI
The OcrInput
class will automatically resolve low-resolution images for IronTesseract
.
Although Tesseract generally requires a 300 DPI input, IronTesseract
has been tuned to work with 99+% accuracy on 225 DPI scans. This can double OCR speed.
Too high a DPI is slow. Too low a DPI causes inaccuracies. If in doubt, do nothing, and Iron Tesseract will preconfigure everything for you.
How to Improve Low-Quality DPI in Tesseract
- Install the OCR library to improve low-quality DPI.
- Construct an
IronTesseract
instance. - Create an
OcrInput
object with the path to the image. - Choose a target DPI value.
- Invoke the
Read
method with theOcrInput
object.
