PBM file ?

Stippling file made using dithering in GIMP, basically indexing the image at 1 color, and then reducing the number of dots by lightening the image (lowering opacity of the original image, is one method).

Big fan of stippling too Mahvin. Weighted Voronoi Stippling is just one form of it. Dithering using Floyd-Steinberg is another. I remember when I first started working in the offset printing business (didn't last long, but it flamed the passion that got me to where I am now) and doing research on all the dithering techniques. Ran across this cool article (same PDF article anyway; had to re-find it; lol) too.

We're not on the same wavelength, Lyle. I was explaining PBM to PC. I used the pbm in Concorde, etc. I used the same pbm file in G'MIC and got weird previews that won't translate to the image.

Ah; you know already that pbm is a bi-color (2 color indexed) format and I bet G'MIC don't like working in color spaces other then greyscale or higher bits.

Fascinating technique that he has.

This one's one of my favorites. Man, it just seems you could automate this, but alas I guess you can't do it. lol

i bet the opposite
But even if i win you are too far to offer me a beer !!
(luckily the same if the winner is you )

Hey Lyle i thought i had a script to do something like this and among my very many i think i found it.I have looked and looked and can not find these python files anywhere on the net now.Nor could i find them at the registry for some reason.But they do alot according to what you are looking for.
Examples
Before using the magic mesh filter (a small dialog screenshot) - Python-FU/Create Layers/MagicMesh


Using the robot as an example:


Now with the robot image removed for clarity


I attached the pythons in a zip if any one is interested
Their are 3 files - MagicMesh3 SVG - MagicMesh2 mask - and reg MagicMesh

Then if you duplicate the dotlayer a bunch of times you can then add the original image on top set to hardlight-


You will find them in the menu here-


You can get some very interesting results playing with the sizes too.

only a attempt to a theoric soluction here :

1 dup the image simplify the dup to the basic shapes :
as exemple a mezzobusto (head neck shoulders and a bit of what below) may be simplified in a ellipse (head) a rectangle (neck) and a trapezio (the visible part of the rest of the body)...hum maybe trapeze is the right word...

then fill the ellipse with circles, the radius of the circle will give the number of circle needed, except then other much smaller circles will be needed to fill the empty spaces

and same for the other spaces to fill,except that for every space you may wish set a different max radius for the circles

then you have to simplify (as with several "artistic" filter) the other dup and to that overlay all the circles

i hope make sense ...here are again 6.30 AM and i am still awake...

Here i ran the MagicMesh script on value and added a bevel and emboss.

Cool look Rod, but it's the random yet structured placement of the circles that I'm trying to figure out how to automate. Close I am, but no where near as good as the master. Again, lazy I am so I try to automate most of the work away. The technique that I outlined is still more work then I would have liked. David replied to my thread at Flickr, but I don't know how to gmic. lol

Jumping in late, you can do some similar things with the Inkscape tiled clones trace function:

I like Ben Heine's Freddie Mercury image too! Being a big fan of Queen, I had to mention this one!

Not a regular Inkscape user (just a few very simplistic things I know and do in it). Care to do a quick outline Rob; I like your result.

Rob's example does look rather random. It would be interesting to see an outline he used, I agree.

The wiki is here:

Hello everyone,

First time poster here. I have been lurking, trying to soak up some knowledge.

I did the attached with Gimpressionist.

OP, thanks so much for the info on Ben's work. It is so special..

How would one go about making one of the stacked circles he uses?

Looks like Ben (these are assumptions, btw) layered another smaller circle on top and added a light drop shadow.

Sorry, I was not clear. I was wondering how to save the image into the user Gimpressionist folder. Is it supposed to be greyscale, flattened, file format, etc?

I have also had no success uploading a signature bmp. I have used the upload photo icon on the edit signature page. No telling where that file went twice now, lol. Using another icon, think it was "upload picture" (looked like a mountain) I also tried pasting the code I got off of the file's Picasa page, but that gave me errors.

So, for now, I am

~~Grits~~
