[Gimp-user] Creating heightmap from a topographical chart
Hello all. This is what I'm trying to achieve: I have a topographical chart (curves that depict the height of a territory) which I want to use as a heightmap for blender. Blender uses gradient grayscale images to raise the pixels of a plane according to the whiteness of each pixel (i.e. the white pixel will be raised to the higher level, whereas black pixel will remain to the bottom. The in-between pixels will be raised according to their value of white). With this in mind someone must create a grayscale gradient image out of the topographical chart. Could someone suggest a smart way to apply grayscale gradient to the image according to the height specified by the curves? My map resembles this one: http://www.atsdr.cdc.gov/HAC/PHA/alaskap/apc-f3.gif And the result I am trying to achieve resembles this one: http://img.photobucket.com/albums/v291/americanfishguy/Buildings/Australia.png The blender effect I want resembles this one: http://gchen.sdf-eu.org/Chengine/Images/Screenshots/HeightMap.jpg Thanx in advance!

I know what you are wanting to do, I'm just not sure the GIMP or even your source map are the right tools for the job. For the GIMP to be able to do something like that automatically, it would have to be able to distingush the isoclines from the river drainages, trail markings, text, etc. Then, once we know which are the isoclines, they would have to be closed (several of them are not), and it would have to have some way of telling which are heading up and which are heading down (which is only hinted at in places with the elevation text). Given that all this is unsurmountable by automated means, we turn to hand driven. Much the same way, you would need to remove everything that wasn't an isocline, and make sure that all the isoclines were closed. You could then select by region with a 0 threshold and fill each isocline with the appropriate color. That would leave the isoclines themselves to deal with, but when you were all done with the (very tedious process), you would have something that looks like your australia map. But, that won't get you to the blender map. You would end up with a terraced effect that would look very strange. You could use a blur to get rid of some of the terracing, but that isn't really whay you want (I don't think). Might I suggest finding out the latitudes and longitudes of the map you want to do, and downloading the DEM data for the region? The data is all available online (legally) for free if you look hard enough, and you should be able to find a high enough resolution for your needs. I personally have a copy of the DEM data for the Earth at a very low resolution (much, I'm sure, than would work for your map). And, I can send it to you so you can get an idea of what you would be looking at if you like.

Btw. since you are obviously one of the wizards, you could have an eye on the manual and give us some wizardish advise ? wizard is probably not a good word. i am not sure what a good word would be. gimp-1.0.2 with no access to a television or other media display until gimp2. when i actually had the opportunity to see how others manipulate images either via animation or film rendering, i was quite astonished. learning it while not seeing it being used is an issue. not always good and not always bad. i have a pile of accomplishments and mistakes that keep me wondering if a word should even be found to describe it. i guess that if life had a configure script, we would all be using it about documentation. i would like to apologize to all of the document writers for a few things. one, acceptable and complete documentation is like a sleeping potion to me. i have some very strong opinions about the software that is used to produce most of it and also have been very rude in that i have not read it. i don't know how to fix that. if i ingest some extra caffiene to combat the sleepy feeling i get while reading good documentation, i am too lively to start to read it. how about this. i do have a little discipline i can access. if you suggest something that should read and comment on, i would actually have enough lively feelings to enable me to open them and read them. i am in a difficult and undefined very weird life for a long while. it would actually be nice to define some of these moments with a reading task like that is this the give the has been a reading assignment part? it certainly smells that way :) carol ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

This is not really a GIMP-related issue, since the GTK libraries became separate from the GIMP a long time ago.

But AFAIK the lack of a + symbol doesn't mean anything. I believe the official name of the package as a whole is GTK+, though specific packagers (e.g. Linux distributions) sometimes omit the +, but in any case the actual shared libraries that get installed on your system don't have + in their names. At least they don't on my system, and I'm pretty sure it's not a meaningful distinction. And if so, where can I download the sources, as I would prefer to compile them myself? You should be able to find them via www.gtk.org. Just beware of replacing newer files with older ones. That *probably* won't happen, since you say you've got the latest GIMP etc. ... that implies you have GTK2 installed, so there shouldn't be any conflict. Still, I'd suggest doing a dry run in a fresh install directory, just to make sure you're not going to overwrite anything important.

Re: [Gimp-user] Layer from selection
Panos Laganakos wrote: Is there a script/action that allows to create a new from a portion of selected section? Right now, I duplicate a layer, select the area i want and crop it to my selection. Sure, it's very simple--though perhaps not obvious. 1. Copy the selection (keyboard: Ctrl + C / menu: Edit - Copy) 2. Paste (Ctrl + V / Edit - Paste) At this point, you would normally do Ctrl + H to anchor the layer (i.e. merge the pasted item into the destination layer, but instead do this: 3. Look at the Layers dialog. You should see an item in the list called something like Floating Selection (Pasted Layer). If you don't see that, maybe you didn't do the first two steps correctly. 4. Make the floating selection into a new layer. In recent versions of the GIMP, you should find a New Layer button (with an icon like a single sheet of paper) at the lower left corner of the Layers dialog. Or there's a New Layer command on the popup menu. In any case, just make sure the Floating Selection is selected in the list, and press that button or menu item.
