I've done this for pictures of my family - my daughter loves coloring us.
 It works best on pictures without a lot of noise to them, but my "recipe"
assuming a flattened (1 layer) image is:

1) Blur->Selective Gaussian Blur - use parameters to get rid of details but
keep main subject sharp
2) Colors->Desaturate (I usually use Average, but not sure it matters)
3) Edge-Detect->Difference of Gaussians with about 8/33 as the 2 radiuses
gets me some basic lines that work good for this on SLR-size photos, use
smaller for values near the same ratio for smaller pictures.  Goal is to
get an outline of the salient features only.
4) Colors->Levels... to make sharp black lines
5) Blur slightly if necessary
6) Save As.. & Print
7) Open box of crayolas and go nuts

If you want to do more of a fake-crayon drawing to wow your friends, change
the levels step to have very light grey output instead of dark black; then
trace the light grey with heavy crayon before coloring in/shading with
lighter shades.  As a bit of warning, eyeballs and cheekbones are amazingly
hard to get right!

Happy GIMPing,

Seth Burgess

Try:

Filters->Edge Detect->Edge...
Use defaults, click OK
Image->Mode->Grayscale
Colors->Invert

Possibly adjust Levels/Curves afterward.

[Gimp-user] Help with colouring book stamp type images

2012-01-23 Thread NoviceGimper
Hi there again

I want to make colouring book pictures for my students from photographs of 
themselves (want to see kids get excited about something - give them a picture 
of themselves to colour in).  Right now I am using the cartoon filter, 
desaturating the image and then painstakingly selecting by colour, each 
greyscaled set of pixels and then cutting them so that in effect, the image 
becomes a traced black and white image.  I am wondering if there is an easier 
way to do this - I have tried using the threshold and levels filters - but I 
find that it makes the image too pop-arty, like those Che Guevara type T-shirt 
graphics.  Ideally I want to literally make the image look like colouring book 
picture or a stamp. Is there an easier way to do that without having to pick 
and delete the greyscaled parts of the image? Any help would be appreciated.  
Thanks
Candice
