You need * -background transparent * in a few more places. I added it to your intermediate convert commands and then it worked fine up to (14). (There is a syntax error involving -crop below, > 5) convert -crop p3m1_G6b.png 1500x1300+0+0 +repage p3m1_G6.png but that was pretty obvious and not the problem.) > Comments and hints are highly appreciated. There is still an error with what follows, I believe. If I represent by "M" the tile produced at step (14), what you want next is this flip-flopped configuration: M W W M Your next step, however, 15) convert p3m1_tile_part.png -flop p3m1_tile_part_flop.png needs to have a -flip, not a -flop, else you get an "MM" for your row and a "WW" for your next row, resulting in MM WW (You've flipped your flips and flops, which makes it flop. :-)) Anyway, when I made that change everything seemed to give p3m1 as a result, although I haven't checked it for "seamlessness". This will be a nice utility (or set of utilities if you are doing all 17 wallpaper groups) when you finish. I recall wanting something like this ages ago, but instead labored to make a single example "by hand".
