Here's a method I came across. Works quite well for certain photos...

Comic Book retro style dots [Re: Camera to Comic Book]

Bugzilla from horkana@maths.tcd.ie

The more detail you provide in your question the better chance you have of
getting exactly the answer you want.  If you want an effect like that seen
in the Rhino picture you need to learn about Halftones, which is very much
retro comic book style as opposed to some of the other simplrer more
straighforward Cartoon effects like:

Filters,
  Artistic,
    Cartoon...

The wikipedia page isn't a bad place to start if you want to learn more
about Halftones:
http://en.wikipedia.org/wiki/Halftone

There is also a plugin for the gimp that can achieve this effect but it
was confusingly called "Newsprint".  The Newsprint plugin failed to
mention the term Halftone in the short description so even when I knew
what I was looking for it still took me ages to actually find the gimp
version.

http://bugzilla.gnome.org/show_bug.cgi?id=301201
Thanks to Michael Natter the next version of the gimp Plugin
Browser has a more flexible search tool which will hopefully make
things easier to find in future but I still think the Newsprint plugin
could benefit from an overhaul/rename/improved documentation.


Here's an example from the RedHat Getting started guide which uses the
Newsprint plugin

Re: Comic Book retro style dots [Re: Camera to Comic Book]

I really like this technique!


Besides the mentioned Newsprint filter there's Gimp's own
Filters/Artistic/Cartoon which can help a lot with the black parts. Edge
detection on a desaturated version of the layer can also help with
delineating the contours



The link that Jad Madi supplied also referenced the original Photoshop
tutorial at
http://www.macmerc.com/sections.php?op=viewarticle&artid=209&page=1

Some of the methods that are used must be done differently in Gimp, but
apart from that it's the same moves. Admittedly I can't get my attempts
to turn out as nice as theirs.

1) The crosshatching technique in the dark areas is very essential to
this. I'm sure real Gimp-wizzes can achieve spectacular results with the
GIMPressionist or whatever but I'm a novice at that.
.. New layer
.. Drag the pattern 'Stripes 48x48' onto the layer
.. Filters/Map/Displace: In X and Y displace source menuboxes choose the
original layer
.. Add layer mask to the layer which should be distorted now (right
click on the layer in the layer menu
.. Copy original layer (select layer, Ctrl+C) and paste to the mask
(left click on mask, Ctrl-X, Ctrl-H)
.. Apply Curves to the mask (Layer/Color/Curves). Set the curve to
something like this: `\_      or   ``|__

2) He often uses a combination of Photoshop's Threshold (for making
something black-white) and a Diffuse filter which does anisotropic
filtering. I can only guess what it does as I don't have Photoshop, but
I think that Diffuse+anisotropic == Filters/Noise/Spread with a bit of
antialiasing to soften up the hard threshold. You should get the same
effect by copying the layer to a new image, double the size, applying
Spread, downscaling with Cubic interpolation and copying back again.
Anybody who knows a better technique?

3) His Filter/Artistic/Poster Edges is somewhat of a riddle to me,
especially since he sets Edge Thickness and Edge Intensity to 0.

4) Then comes my biggest problem: He uses Filter/Artistic/Cutout which
has it's closest sibling in Gimp's Image/Mode/Indexed (applyed to a copy
of the layer - set dithering to None, not Floyd-Steinberg, and a low
color count) or perhaps Layers/Colors/Posterize.
HOWEVER this renders very noisy borders between color bands. How to
simplify the borders is beyond me, unless one does a
Filters/Blur/Gaussian Blur first, but is that good?
Perhaps use Filters/Noise/Spread a bit to loosen up on the sharp color
areas

5) He uses the original layer with blend-mode 'Color' for changing the
colors of his posterized layer. I don't think that Gimp and Photoshop
uses the same blend-scheme because he recommends changing both the
saturation and lightness of the color-layer for cartoonish style.
Nothing happens in Gimp when I change the layers saturation. But making
a second layer with mode set to 'Saturate' does somewhat the same.


That's what I can think of right know..

Centipede

Oups, Alan already mentioned the Cartoon filter :)

I don't have "Cartoon" under my Filter/Artistic menu entry.  I will
find it in the gimp plug-in registry.  If it's not in the plugin
registry then please tell me where I can find it.

Best regards

Well, at a guess I would say that if it's not there it hasn't been built.

When you built it, did you read the configure output to see what was not
being built, and why?

You are probably still using GIMP 2.0 then.

For those interested, I have started to make a number of hatchings (or
whatever you say in english). Hopefully they are a little bit prettier and
more natural to use as fillings of dark areas than the clean stripes you get
from wrapping pure lines. I'll add rotated versions too to be used as second
layer for making crosshatches.

So far there are only two, but I have more in the drawer coming up.

They can be found at:
http://artcamilla.dk/vaultage/cornucopia/gimp-patterns/ under the names
hatch-XXX.
The reason I used .PAT files instead of just .JPG is that I could specify a
more descriptive name than the name of the file. If these cartoon endeavours
turn out okay, I might make a plug-in for it.

Regards,
Centipede

Hi,

Alan and Sven, thanks for the help.

Yes! 2.0.5.  I did downloaded some dependencies for 2.2.6 and will now
download any dependencies for 2.2.7 that differ from 2.2.6.  As a
learning task, I want to install Gimp from source-tarballs including
all the dependencies under my home directory.

Yes, I should have searched appropriate resources before posting my
query!  I am sorry!

Yes.  Thank you.
