Frequently Asked Questions
Common questions about our Sketch Effect tool.
How does the Color Dodge sketch algorithm work?
Our pencil sketch filter grayscales the original image, inverts it, applies a fast CSS box-blur kernel to isolate structural borders, and then blends them together using a Color Dodge division algorithm. This mimics physical graphite shading by lightening light areas and adding high-contrast strokes to edge transitions.
What is charcoal outline mode?
Charcoal outline mode utilizes a custom 3x3 Sobel gradient convolution filter. It computes high-contrast spatial derivatives to extract boundaries and contours, inverting them into charcoal ink strokes on a selected paper texture.
Can I adjust the final sketch's texture and paper grain?
Yes! Our Paper backdrop system procedurally generates randomized micro-grain noise overlaid on warm parchment, canvas, or kraft papers, allowing you to fine-tune texture depth and color matching.
