In PicToBrick, once you've generated a mosaic an "Output documents" button appears just below the "Generate mosaic" button - click that new button and you get a list of output options at the top of the control column. Tick the "Image" checkbox and press the "Generate documents" button at the foot of the list.
PicToBrick will then create a new folder for the mosaic (in the configured working directory) - in there is a subfolder "data" containing a file "mosaic.jpg". (You can ignore all the other output options and bumph generated!)

Thanks for the reminder Kevin; haven't installed all my Script-fus/Python plugins since my computer crashed a few months ago. Will soon do so, but not at the moment (brain drain right now; lol).

Thank you jontait2. I will have another look later.

I just wish Pic2brick would allow you to re-open the file for additional tweaks. They've not updated the program in a long time now either. Maybe I asketh for too mucheth. lol

OK; had a brain fart and figured out a way to get the selections (still convoluted, but doable). Now I can do a better job at creating 3D Legos but now the lego pieces won't a have the seams that the original tute (don't ask me the link; way too lazy to find it) had (i.e., you can have distinct pieces like right angles, multiple lenth straights, vertical and horizontal, etc.).

I don't think there are any well-defined rules for Ministeck but one element used is randomness- if you run PicToBrick repeatedly on a solid colour background you'll find it produces different results each time!

I'd never heard of a "ministeck" before, but this looked like an interesting puzzle. Here's a G'MIC custom script that will sort-of replicate the concept:

Code: Select all

RescaleSmallestDim=128 RescaleMethod=1
Colors=7 ColorMethod=1 MapContrast=1.0 Dither=0.0
TileSize=5 TileHighlight=0.10 TileShadow=0.15
PixelSize=2

-repeat @# -l[$>]
-resize_ratio2d $RescaleSmallestDim,$RescaleSmallestDim,1,$RescaleMethod
--colormap $Colors,$ColorMethod AA={ia} --[-1] $AA -*[-1] $MapContrast -+[-1] $AA
-index[0] [-1],$Dither,1 -c 5,250 -rm[-1]
--l --[0] {im-1} MM={iM} -s c -repeat @# -+[$>] $> -*[$>] {($MM+1)^$>} -done -+
--label_fg[0] 0 --area_fg[0] 0 -repeat 3 --neq[2] {$>+1} -*[0] [-1] -oneminus[-1] -*[-1] [1] -done
--r[0] 50%,50%,@{0,d},@{0,s},1 -r[-1] [0],1 -replace[-1] 0,-1 -neq[-1] [0] --oneminus[-1] -*[-1] [1] -*[-2] [1] -rm[0,1,2]
50%,50%,1,1,'x+y*w' -r[-1] [0],1
-mv[-1] 0
-r {$TileSize*100}%,{$TileSize*100}%,1,1,1
-repeat @# -l[$>]
(1,0,1;0,0,0;1,0,1) -normalize_sum[1] --convolve[0] [1] -rm[1] -- -eq 0
-endl -done
-min -dilate 2
(1,0;0,-1) -convolve[-2] [-1] -rm[-1] -+[-1] 1 -c[-1] {1+$TileHighlight},{1-$TileShadow}
-endl -rv -r[-1] {w*$TileSize},{h*$TileSize} -shift[-1] -1,-1 -*[-1] [0] --[0] 1 -*[0] 128 -+[-1] [0] -rm[0] -r {w-1},{h-1},100%,100%,0 -r {$PixelSize*100}%,{$PixelSize*100}%,100%,100%,1
-endl -done

All the parameters are in variables at the top. It'd be easy enough to make it an entry in the GIMP plugin.

Unfortunately I don't really know the "rules" of designing a ministeck. For example, a lot of the solid color areas could easily have been filled with 2x2 squares, but were not by the programs mentioned already in this thread. Why not?

Attached is the result on your forum icon, Lyle, except with "MapContrast" set to 0.9 (for dimmer white/black tiles).

Nice!

Not sure why the compiler can find the executable but not the header and lib files.

I just copy/pasted into G'MIC's Global input and created a preset Rod. That, at least, worked for me. Kept it all in the GIMP too; easy/peasy.

Ah, OK, well I can do that.

Here's a version with randomness, and also works on images with alpha.

Code: Select all

RescaleSmallestDim=128 RescaleMethod=1
Colors=7 ColorMethod=1 MapContrast=1.0 Dither=0.0
TileSize=5 TileHighlight=0.08 TileShadow=0.12
PixelSize=2

-repeat @# -l[$>]
-resize_ratio2d $RescaleSmallestDim,$RescaleSmallestDim,1,$RescaleMethod
-split_opacity --colormap[0] $Colors,$ColorMethod AA={ia} --[-1] $AA -*[-1] $MapContrast -+[-1] $AA
-index[0] [-1],$Dither,1 -c[0] 5,250 -rm[-1] -a c

--l
--[0] {im-1} MM={iM} -s c -repeat @# -+[$>] $> -*[$>] {($MM+1)^$>} -done -+
50%,50%,1,1,'x+y*w' -r[-1] [0],1 --*[-1] 0 -noise[-1] 25,2 -*[-1] -1 -n[-1] -1,1 -*[-1,-2]
-repeat 6 --*[-1] 0 -noise[-1] 1,1 --dilate[-1] 3 -eq[-1,-2] -area_fg[-1] 0 -eq[-1] 1 --label_fg[-1] 0 -*[-2] [0] -dilate[-2,-1] 2 -replace[-2] 0,-1 -eq[-2] [0]
-area_fg[-2] 0 -gt[-2] 3 -oneminus[-2] -*[1] [-2] -*[0] [-2] -oneminus[-2] -*[-1,-2] -done
-r {$TileSize*w},{$TileSize*h},1,1,1
-repeat @# -l[$>] (1,0,1;0,0,0;1,0,1) -normalize_sum[1] --convolve[0] [1] -rm[1] -- -eq 0 -endl -done
-min -dilate 2
(1,0;0,-1) -convolve[-2] [-1] -rm[-1] -+[-1] 1 -c[-1] {1+$TileHighlight},{1-$TileShadow}
-endl

-rv -r[-1] {w*$TileSize},{h*$TileSize} -shift[-1] -1,-1
-split_opacity[-1] -*[1] [0] --[0] 1 -*[0] 128 -+[1] [0] -rm[0] -a c
-r {w-1},{h-1},100%,100%,0 -r {$PixelSize*w},{$PixelSize*h},100%,100%,1
-c 0,255
-endl -done

By the way, as it turns out, I had set up a lot of steps in my original (more boring) script in preparation for adding randomness...but never actually did when I posted it. So, there was a lot of 100% useless calculation going on. Oops! :oops:

I've edited my original post with a cleaned-up version, that also works on images with alpha channels too. It's also in the following spoiler.

Now I'm definitely liking this on Clouds. Now, if you can branch out to rectangles, it can be used as a foundation to create Legos.

lylejk · **Joined:** Sep 24, 2010 **Posts:** 12518

Now, if you can create some sliders to adjust size and such. Yes, I asketh for too mucheth. lol

I suppose I could just modify the code for adjust the size for now.

Thanks again Clouds (until you are willing to share your real name, then Clouds it is).

lylejk · **Joined:** Sep 24, 2010 **Posts:** 12518

OK; toyed with your preset some so that I could get the outlines only to isolate the tiles (oh; made the tiles bigger too; lol), and then blended some textures and such to get this bathroom tiled result. So many possibilities for your G'MIC preset Cloud. Your code is extremely small too. Thanks a heap again.

lylejk · **Joined:** Sep 24, 2010 **Posts:** 12518

Just some more tweaks; you made me a monster Clouds. lol

Set the white grout to zero, and then use erode followed by dialate to get just black lines. I then used that as a mask and ran Graechan's Plastic or Glass for the tiles (overlay). Added stoney grout.

Excellent.
Ran the default code over this image repeatedly 4 times then the original over that with my own Rodilius options and inverted the colors.Set the top Rodilius layer to difference mode.

Trying to get a good woodcarving effect with color balance after. Not bad.

With the script.
