Editing a world map

[waldronate]

The documentation file at the Wilbur home page is a little out of date, but it covers most of the basic features of the software. The way I see your problem, though, is that you're asking "how do I do this to my map" and the documentation covers more along the lines of "here's what the software feature does".
http://www.cartographersguild.com/ma...-wilburia.html and http://www.cartographersguild.com/ma...und-lands.html have examples of using an outline and mountain mask to generate results in Wilbur (the second one with a fairly detailed tutorial).

http://www.cartographersguild.com/so...sting-map.html may offer some suggestions for your first case. Another technique is to use the lasso tool to select the area at the base of the mountain(s) and then use Filter>>Fill>>Mound with Operation Add to fill the area.

Changing the color of the ocean depends on the shader that you're using. Some shaders have no notion of "ocean" at all. For the basic Wilbur shader, it would be Texture>>Shader Setup, Altitude page. The Color List button under "Sea" controls coloring of all areas on the land below "Sea Level".

Changing a contour map to a height field is the same process as described in the CSU Johnsondale tutorial, except that you convert each contour level to a solid mask. There are some examples of that process at the guild, I think.

Note that asking questions about Wilbur's operation is an excellent option, as I have it on good authority that the author of the software will sometimes answer such questions.

Many thanks Waldronate. Most kind from you.

You exactly hit the nail on the head - my problem is indeed "How do I apply the fractal Tools on a preexisting map ?"
In the meantime I learned a lot and am much better able to explain what I want to do than I was yesterday.

First I gave up on Wilbur as it is indeed rather difficult and too full of concepts I am not really familiar with.

I then settled on Fractal Terrains 3 and I can already use it reasonably well (have still difficulty to understand how the selection buttons work and what the options do but ....)
So as I have a PNG file of my map and can transform it in any reasonable format, I thought that my problem was solved because I only had to load my file into FT3 and then work it with the Tools.
Seemed simple enough untill I realized that while FT 3 can export in about any format, it can import basically nothing and in any case not PNG.

I spent then several hours trying to load the PNG in Wilbur (who can apparently read it but I am unable to edit it there by tracing f.ex the contours etc) then saving it with all possible extensions and then trying to load it with FT3.
All attempts failed but one (when i used the format 8 bit .bmp file) where something appears in FT 3 but it is so distorted and scrambled that I can't use it.

So basically now my question is clearly formulated : How can I transfer map contours contained in a PNG file into FT 3 ?
Alternatively I could just use the coordinates and recreate the contours directly in FT3 but I have found no fast way. Clicking on raise altitude finishes to make appear a piece of the contour in about 2 minutes on a length which is perhaps 1/500 of the total coast length so that I would spend more than 17 hours just tracing the coastlines. This is definitely too much.
Isn't there a way to trace a coastline in FT 3 directly in less than 1 hour ?
