Traditional laser engraving software uses basic processing methods (like Jarvis, Atkinson, or Floyd-Steinberg dithering). These methods have limitations:
: It supports the compression of multiple images at once, making it efficient for handling large collections of images. xtool brunsli
This is the key difference. Brunsli doesn't just decide "dot on/off." It creates a map of varying laser power levels (often across 8-16 effective grayscale levels) by using sub-dot pulsing . The laser fires multiple micro-pulses within a single dot's space to simulate a lighter or darker shade. xtool brunsli

"xTool Brunsli" appears to be a combined reference to , a leader in desktop laser cutting and engraving technology , and Brunsli , a specialized library for lossless JPEG recompression .
