Emboss and Engrave Image Filters
no vote
This project demonstrates a full implementation of the traditional "Emboss" and "Engrave" image filters. A grayscale version of these effects can be calculated using any custom filter engine (see, for example, http://www.tannerhelland.com/982/custom-image-filters-vb6/). However, this full implementation is faster and lighter than a custom filter engine, and it also provides the option to Engrave / Emboss to a specific color.
