Image Emboss Filter

How Image Emboss Filter works

Image Emboss Filter is designed to apply a directional emboss convolution to local raster pixels. A directional convolution subtracts upper-left neighbors, adds lower-right neighbors, scales the response, and applies a neutral 128 bias. Image Emboss Filter adds a focused result for this operation. For Image Emboss Filter, its displayed result gives the current settings a concrete value that can be checked before anything is copied or downloaded.

The directional 3 by 3 emboss kernel adds a neutral 128 bias after comparing diagonal neighbors. Use it to derive a relief-like texture or inspect directional edges before combining the output with another design layer. In Image Emboss Filter, that reproducible starting point makes later changes easier to evaluate because the underlying method stays constant.

Limits, output, and privacy

Flat areas become middle gray, and increasing strength can clip both highlights and shadows in high-contrast regions. For Image Emboss Filter, large source images require more memory because the browser holds both source and output pixel buffers while processing. Image Emboss Filter keeps the operation client-side. With Image Emboss Filter, the page processes its source locally, then copies or downloads the in-memory result without uploading it.
