Deskew Scan
Detects the skew of a scanned page (the angle that best aligns its text lines, searched to 0.05°) and rotates the image straight, filling corners with white. The detected angle and the residual after correction are reported — you can see the number, not just the picture. PNG out, same pixel size.
A little guidance. A better result.
How to use Deskew Scan
Detects a scanned page's skew to 0.05° and rotates it straight; the angle and residual are reported as numbers.
Prepare your input
Choose an image of a scanned page.
Use the workspace
Review the detected skew angle and corrected result.
Check your result
Check text lines and page edges before saving PNG.
Know the limits
The canvas keeps its size, so inspect edges for clipping. Detection is an estimate, not OCR.
