Image Deskew
Straighten with precision!
Automatically correct skewed and rotated images.
About This Plugin
The Image Deskew plugin provides advanced skew detection and correction for .NET applications. Using sophisticated algorithms including Hough transform and edge analysis, this plugin automatically detects and corrects angular distortions in scanned documents, photos, and images. Essential for document processing, OCR preparation, photo correction, and any workflow requiring precise geometric alignment of image content.
.NET Prerequisites
- Microsoft Windows or a compatible OS with .NET Core
- Development environment: Visual Studio Code or Microsoft Visual Studio
How to Use
Reference Imagise Image Deskew
Add the Imagise.ImageDeskew NuGet package to your .NET project and include the required using directives to access the deskew functionality.
Set License Keys
Configure your license credentials using the License class to activate all deskew detection algorithms and processing capabilities.
Create Deskew Instance
Initialize an ImageDeskew object and load the skewed image you want to correct from a file path, stream, or existing image object.
Configure Deskew Options
Set detection sensitivity, angle range limits, background fill color, and whether to use automatic or manual angle detection mode.
Process Deskew Operation
Execute automatic skew detection and correction. The plugin analyzes image edges and text lines to calculate the precise rotation angle needed.
Save Corrected Result
Export the straightened image with the calculated rotation applied and optional autocrop to remove empty borders created by rotation.
Key Features
Automatic Skew Detection
Advanced algorithms using Hough transform and edge analysis automatically detect rotation angles with precision up to 0.01 degrees for perfect correction.
Document-Optimized Processing
Specialized processing mode for text documents uses text line detection for more accurate angle calculation, ideal for OCR preparation and document scanning.
Batch Processing Support
Process multiple skewed images automatically with consistent settings, perfect for digitizing document collections or processing scanner output.
Smart Border Handling
Automatically crop rotated images to remove empty borders, or fill them with smart background detection for seamless results.
Frequently Asked Questions
How accurate is the skew detection?
The detection algorithm achieves precision up to 0.01 degrees for most images. Accuracy depends on image content - documents with clear text lines or strong edges provide the most reliable detection.
Can it handle severely skewed images?
Yes, the plugin can detect and correct skew angles up to ±45 degrees. For extreme angles, you can use the manual angle specification mode or combine with the rotation plugin.
What happens to empty corners after rotation?
You can choose to fill empty corners with a specified color, use smart background detection, or automatically crop the image to remove all empty areas while preserving maximum content.
