Hello everyone in mosaic land, I've been lurking on these forums for many years and this is my first post! I have been a Lego fanatic for 30-odd years and as a very busy adult, the time I have been able to devote to Lego has declined quite a bit (...) (21 years ago, 28-Mar-05, to lugnet.build.mosaic)

(...) I'd say it looks like the image on the right was contrast enhanced before the dithering was applied. Stand back and squint at the images to see the change in contrast. The light colors are all clearly whiter. You can also see some color (...) (21 years ago, 15-Feb-05, to lugnet.build.mosaic, FTX)

I don't make artistic mosaics, they're purely mathematical. I (...) (21 years ago, 15-Feb-05, to lugnet.build.mosaic, FTX)

Bob, One more suggestion: Because there is no "brickwall"-structure in your MLCad results, it might not be such a bad idea to alternately read lines from left to right and from right to left. In my program I also have something like this: For I = 0 (...) (21 years ago, 8-Feb-05, to lugnet.build.mosaic)

Tips & tricks: 1) If you decide to convert an image without dithering (e.g. a cartoon character), you may have noticed that a significant part of the image turns (dark) grey (in case this colour is in your list of colours to be used), even if you (...)
