This tool generates random tree coordinates from a set area that one has colored. The idea with this tool is to reduce work time with making the trees. If done manually, one has to set the coordinates for every tree and change them if they are not on the right place. This process can be tedious if you want to add hundreds of trees to, for example a new landmass. By using this tool you will save alot of man-hours. In fact, the process is so quick that if you are not content with the trees, just do it again. The randomness of the generating will assure you that the next seed will not be the same at all.
My thanks to taw for his help with Shogun 2 converter and converting campaign.tree_list file.

Installing
Spoiler Alert, click show to read:
First you need to install python 3.3. That can be done on this website:http://www.python.org/download/ (If on windows, pick the download at the top. Make sure to install python at C:/Python33, i.e the default installing directory). Then you need to download and install the PIL module, you need only to run the installing program. Pillow-2.3.0.win32-py3.3.exe (md5).
After you have done that, in order to make the trees after you have used this tool you need to use the Shogun 2 converter tool, made by taw and husslertw. Download:http://www.twcenter.net/forums/showt...-update-30-03)
1. From data.pack in Shogun 2/data folder, extract the campaign.tree_list file that is in campaign_maps/"campaign of choice"/display/Trees
2. Put the campaign.tree_list file in a part of the Shogun 2 converter directory.(S2C/Shogun2 Converter/ESF) That means the first ESF folder you stumble upon, not the one inside it.
3. Go back to (S2C/Shogun2 Converter) and hold shift, rightclick "ESF" folder, open command window.
4. Write this: "jruby --1.8 esf2xml campaign.tree_list unpacked".
5. When that is done, go to the unpacked folder inside ESF folder. Open tree_lod_list with any text program(notepad++ recommended). Let it be opened for the time being.
6. Extract heightmap.tif from data.pack and (campaign_maps/"campaign of choice"/display/Heightmap) into the folder where the python script TreeGenerator.py is. Convert it to .png and save it as "PaintArea.png"(Capitals important).
7. Paint on the area in the png where you want your trees(additional info regarding this can be found in readme, like RGB).
8. Save the image and run the python script. Let it run for a while, will take some time. It will then ask you for the number of trees you want added into that area. It will also print some info you can ignore.
9. Open the MyFile.xml with notepad++ or whatever and copy all the entries except the head one(displaying how many trees you added) and paste them into the tree_lod_list file among the other, similar entries. It is divided into parts which represent different treesorts. Paste into one of these. Under the line that tells you what sort it is(ex <s>campaign_maps\vegetation\climate\japan_campaign\trees\spruce_groupb.rigid_model_v2</s>) and the "u" value, paste the tree coordinates from MyFile. Add the number of trees to the value of u, for that part of the document. If u was 250 before you added your 100 trees it must be 350 after. Save the file.
10. Go to the same command window as before(open it again if you closed if previously).
11. Run this : "jruby --1.8 xml2esf unpacked campaign.tree_list" and then go into the ESF folder. The campaign.tree_list file in there is the new one you just created. Append it to your mod into the same directory as the default one you extracted.
12. Run Shogun 2 and check the area on the map where you added the trees.
Possible bugs that you should be aware of:
1. If no or few of the tree sorts except the one you added your new trees to is visible on the campaign map it is very likely that you have not altered the "u" value accordingly to how many trees you added, or you might have altered the wrong "u" value for another tree sort.

Yeah, I know. The tree generator doesn't work or FOTS, only Shogun 2. Have you any ideas how to fix that for FOTS?

So ive asked 2 buddies in class, they say that the index error means that something isnt defined properly. Lets say theres a range of 0-10 maybe youve only depicted 0-9. Also I think since the first 79 line error is saying random.py maybe you havent defined the RGB color properly in the depicted area.
Another thing is the guide asys 3.3 so maybe try that version?
ALSO izzi, hes working on S2 not FOTS. So i dont think thats the problem

The code shows that the RGB colour has been defined and the problem seems to be with the placement of the trees. Basically if the code finds a pixel that's the right colour it will create a tree a random distance from this pixel. However for unknown reasons the code to calculate a random distance isn't working and I don't know how to modify the code so it will work. Havie it may be helpful if you can have one of your buddied look at the code and recommend a different way to calculate random numbers.

Normally, the code works with Shogun 2 TW. But not with FOTS. Also, the resolution in FOTS is (I guess) 4096 by 4096. So what is the factor value then? (the factor multiplies the values of trees?). The max. xy value (for FOTS) must be than 16777216. If use the python version that is mentioned (3.3) and jruby version, than for Shogun2 it works. But the strange thing, is that it doesn't work with FOTS. I mean the python script yes, but when starting with jruby not.
I have tested again and yes, I have the same issue now as you have. The random tree value doesn't get properly values to put the trees around the pixel.
I wonder if the problem is with the PIL module or the code using it, as this part of the code looks at the image and determines which pixels are red. If this doesn't work correctly then the tool won't know where the trees should be located.
I think that's a possibility. Line 79 "pixeltrial = random.choice(pixels)" also makes it difficult to add the trees at the (specific) coordinates. If you just add the RGB coordinates (the variable pixels), than off course, the trees are to close towards each other. Something goes wrong when randomly putting the trees around the specific radius of the RGB sample.
Okay I figured out how to get this app to work. For some reason if you make the PNG file with Photoshop it won't work, but if you convert the PaintArea file to a PNG file using Infranview it does work.
Is there anyone who can explain why some PNG files work while others do not?

Yes, you are correct uanime5. Photoshop is making the issue. Do the work in Photosshop and save as .tif file and after open in Infraviewer and save as .png. Worked as expected.
The only issue I have is that the coordinates don't really match with the real coordinates on the map. I think I have to lower the factor amount (I did lowered the resolution to 8192 x 8192 to fit the FOTS map). The factor is 12.8, how much do I have to lower you think? All the rest in the script, I already fitted the towards the FOTS map (because FOTS map is smaller than the normal STW2 map).

It looks that the trees don't get added in game. I did a test, but no trees on the campaign map. Do you have those issues also?
Great work guys!
So bizarre about the different PNG issue.
Uanime sent me a photo on steam, it appears he has gotten the trees to show up in game Izzi.

Yeah, I got no idea why they don't show up in game. I looked at the coordinates, and they where fine. Also, the tool was specially made for STW2, so I have no idea if it should work for FOTS.
