اس ٹول کے بارے میں
The PDF Scan Aligner is a mandatory utility for sanitizing tilted digital assets and mobile snapshots.
Documents scanned via physical flatbeds or captured quickly with smartphones often carry subtle rotations. Tilted pages look highly unprofessional, hinder text readability, and cause margins to clip during printing.
This tool utilizes robust Radon Transform and Hough Line detection algorithms to scan gradients and text lines under 20ms. It precisely measures skew down to 0.01 degrees and performs pixel-level Canvas rotation, snapping your receipts, contracts, and booklets back into crisp geometric alignment.

اکثر پوچھے گئے سوالات
How is document skew detected?
We run high-speed Hough Line projections on text lines. Since formal prints have clear horizontal spacing patterns, finding the angle with the maximum variance isolates the rotation.
Will this process crop away page edges?
No. The engine calculates the rotated boundary and extends the Canvas using auto-padding, ensuring all margin text remains intact without cropping.
Does it support documents filled with diagrams?
Yes, as long as there is an underlying structure of lines or general paragraphs, our algorithms can accurately lock onto the principal reading angle.
