Perhaps this would be useful?
http://code.google.com/p/openpdn/source/browse/src/tools/PaintBucketTool.cs

So I'll look for a "connected" algorithm and then I'll apply from all 4 corners sequentially, if they're not been already replaced.
Don't have a clue on such algorithms, if anybody has any idea I'll be waiting for it :P

Can't you start at the top left of the picture? If that is black, then replace it and go further down and right (e.g. coordinates (0, top-1) and (1, top)). If not then stop for that pixel. Kind of recursive algorithm.

@tygerfish: thanks for that, it's what I was looking for, but I think I found one too which is pretty short and seems to work. I'll keep it anyway, and check it out, compare, and implement the one that looks better.

@combuijs: yep, that's the base for a floodfill algorithm. I'm not the most skilled programmer around, so I think I'll ask for some code to some "experts" in the net (googling is fast, got a couple of algorithms in few searches).
...
Well, finally found some code out there in the net that I think will work as a floodfill algorithm. I can execute it from all four corners and looks like working. Maybe I can upload a "beta" before going to bed.
Thank you very much guys for your answers :)



Done, you can download the binary here to test it: http://zeno.simutrans.com/Files/SimutransRPP_161.7z
About that, you better not paint vehicle's tyres in black, otherwise they'll go away without them! :D
Instructions are: press once the "BG" button to leave it checked; then load your images; they will have black background removed (at least, that's the idea).

PS did you get any further with the blender script and blender 2.6?

I have my version working with 2.6, which is a modification of my original modification of your modification of Zeno's original script...

Does it have any extra feature or different thing, or just upgraded for executing in 2.6 without errors?

I'm not sure which version that you are comparing it against: I think that I only changed the version numbering from my original modification of The Hood's modification of your original script, but I made some substantial modifications to The Hood's version in order to get vehicles to align automatically.

For reference, here is the full script for the latest version of Blender:

Code: [Select]
bl_info = {
    "name": "Render Simutrans Views Pak128.Britain-refresh",
    "author": "Zeno, the Hood and James E. Petts",
    "version": (1, 3),
    "blender": (2, 6, 1),
    "api": 35853,
    "location": "Render >  Render8viewsBrit",
    "description": "Renders direction views for Simutrans",
    "warning": "",
    "wiki_url": "",
    "tracker_url": "",
    "category": "Render"}

"""
This script has two functions:

1)  Render 4 or 8 fictional views for simutrans game
    What it does is placing the camera and sun in each proper position to make
    each of the requested renders, that means the camera and sun (light) move
    around the objects in the scene, and take the proper renders.
    Ther renders are saved to disk with direction suffixes, such as _W (for west
    view), _NE (for north-east view), and so on.
2)  Enable mask mode for simutrans post processing
    This enables mask mode for the used materials in the scene. That means, the
    script searchs for every material which name starts with "sp_" (special) and
    when found applies the mask to it. The masks changes are:
    a)  Replaces sp_Dark_Wi*, sp_Cold_Wh* and sp_Red_Lig* with the mask color
        (1,0,0.5 magenta), and sets shadeless on for them.
    b)  Sets shadeless on for sp_* materials.

RECOMMENDED:
    * I recommend NOT SAVING the model after using the "Make Masks" function.
    It's much more easy to save your blend file before, then when you need to
    render the masks use the "Make Masks" function, do the renders, and then
    switch back to your blend file back.
    * Be careful when naming your materials. Everything that starts with "sp_"
    will be considered a Simutrans special color!!!!

Be sure to take a look at our Simutrans International Forum at:
http://forum.simutrans.com

You're also welcome to our IRC Chat Room, at #simutrans channel in quakenet network.


History:

v1.0
----
Basic 4/8 view rendering
Masking function for materials named sp_*
Compatibility with Blender 2.56 beta

v1.1
----
Compatibility with Blender 2.57
Several changes to the Masking funcitonality. Read description above.

v1.2
----
Correct alignments for Pak128.Britain without copying and pasting to templates.

v1.3
----
Correct direction names for Pak128.Britain (were 90 degrees off with the Pak128 version)

Hey, Zeno. You might want to update the 1st post, the download link is broken and perhaps the description needs a spruce-up.

BTW, good job dude. :D

Link at first post updated, thanks Igor for reporting.

About the script, thanks very much for sharing your modifications james. I'll take a look to the script, I'll try to fix errors if any and then upload the newest version to the project page.

Note that my script has modified alignments for exporting Pak128.Britain vehicles (other than road vehicles, which have a different alignment), so it might not work for Pak128, as the alignments are different to the original script. It is designed to work so that no further alignment work is needed after rendering.

Has anyone ever managed to get this working under Wine? Attempting this in Ubuntu 16.10, I get the error, "there is no windows program configured to open this type of file".
