Tool usage guide
The Image Projective Transformation tool allows you to apply precise homography-based geometric distortions to your images, enabling advanced 3D surface mapping and custom perspective projection effects.
Background
A collection of historical documents was photographed at an angle, making them difficult to read.
Problem
The text appears skewed and distorted due to the camera angle.
How to use
Upload the document image and input a calculated homography matrix to flatten the perspective.
[[1.2, 0.1, -50], [0.05, 1.1, -20], [0.0001, 0.0002, 1]]Outcome
The document is rectified into a standard top-down view, restoring readability.
Background
Need to place a flat logo design onto a photo of a building facade viewed from an angle.
Problem
The logo needs to match the perspective of the building wall.
How to use
Upload the logo image and apply a projective transformation matrix to match the building's vanishing points.
[[0.8, 0.2, 100], [0.1, 0.9, 50], [0.0005, 0.0001, 1]]It is a mathematical array used to calculate the new position of every pixel in an image, allowing for rotation, scaling, shearing, and perspective warping.
Bilinear is recommended for a balance of speed and quality. Use Bicubic for higher-quality results with smoother edges, or Nearest Neighbor for faster processing.
Yes, by selecting PNG as your output format and setting the background color to 'transparent', the tool will preserve alpha channel information.
You can upload JPEG, PNG, WebP, GIF, BMP, and TIFF files. Output can be saved as PNG, JPEG, or WebP.
The tool supports file uploads up to 10MB to ensure stable processing performance.
Outcome
The logo appears naturally integrated onto the building surface with correct perspective alignment.
