Image Resolution Optimization (DPI)

The OcrInput class will automatically resolve low resolution images for Iron Tesseract.

Although Tesseract generally requires a 300DPI 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.
