GIMP and maps

Scheme is a real programming language - not exactly C or C++ popular, but it existed before the Gimp.

True and its used as part of many projects. One of interest to me (and maybe Johan) is scsh which is a scheme shell for the unix environments (GNU HURD compliant). Im debating that since I do alot of trouble-shooting on other peoples machines. Ive tried not to get too attached to things I wont find on other systems.

It just reinforces something I say about GIMP. Its not the kindof paint program you use. Its the kindof paint program you learn.

OK now that the DomMap project is creating playable maps for Dom2 I would like to clean up the ones Im auto-generating.
http://www.techno-mage.com/~dominion...s2/RandomMaps/

The maps look better blurred. Easier on the eyes. But that messes up the capitals.

My thinking is to capture or set aside the white dots, then blur/smear/smudge/despeckled the map, then paste the white-dots back down. Maybe something like copy all of a color (255/255/255) to a layer, blur, then mrge layers?

Better yet if it could be 3 colors, the white and the two borders. Best of all if it could be scripted.

You needn't script it. At least, I dunno how to do that

It's a matter of a few seconds, anyhow.
Letme try to show how. Sorry if I don't get the menue item names right - I'm using the german Version and can't really remember the english labelling from the previous Version.


Right-click on the pic. Use "select", "per color" (or something like that, it's way down the list that pops up), turn "impreciseness" down to "0", klick on a white pixel.

open the layers menue.
right-click on the pic again, choose "selection", "floating"

in the layer menue there will appear a "floating selection" entry, already marked as active (blue)

hit "keep transparency", than the "new layer" button. the floating selection will be converted into a transparent, "floating layer".

you may rename it to "pixels" or something ...

Activate the backgraound layer, do any smoothing and anti-aliasing you wish.

Proceed similarly for other colors to generate borders etc.

If you add another layer for "objects", you may copy in trees, bushes, mountains etc. from another pic easily. You may even select them later again and move them around by dragging - as long as you keep them on a seperate, transparent layer.

When done, merge all layers.

hope this is helpful

Yeah almost worth learning Scheme just to make a script-fu of it.

OK thats great, and I will do it. But Im not going to do it to 30 files every day.

Maybe if I find a really good one in one of the batches I will do this and then use it as a basis for one of my fun random things.

Maybe if I copy the steps to one of the gimp or scheme newsGroups I can get someone to script it out.
Thanks for the steps.

WOW thanks Arralen! That worked SO WELL.
Here is a short Version I worked up for use with my Windows Version of GIMP

load .tga and open layers
Rclick image, select-> by color, choose color, Shft-Ctrl-L
go to layers, clik "keep transp", clik "new layer"
select original layer, repeat above for both border colors
after getting 3 transparent floating layers, select blur
Ctrl-M to merge all layers then save

Now if I could just get someone to autoscript it

A note on the routine used to make the DomMap images alittle more pleasing to the eye. Ihave dicovered that using the SCATTER effect before doing the BLUR makes a much nicer result. Scatter basically takes large areas of a single color (green, blue, tan) and mixies it up abit with sight variations. If I use it at a setting of 8 then the green area becomes a mix of greens within 8 slight variations of the original shade. This works well for adding alittle visual variety to provinces that ended up a solid block of color. Especialy the water.
