To convert it into 16 colours just use Irfan..
But I didn´t find the best software for creating those maps. So I still use win painting.

Irfan? Ifranview?
win painting? MS Paint?

Yes, sorry

Can anyone explain why enum{ FOO, BAR, BAZ, ...}; is so evil, and must be enum{ FOO=0, BAR = 1, BAZ = 2, ...};? (specifically, the fios constants in hal.h)
Does it really matter what values those constants get? And are there really any compilers anywhere that provide some *OTHER* values? (Read: Doesn't the standard specify that the first and the second are always exactly equivilent?)

More on-topic, it appears that the PNGMap patch got slightly out of date. I've rectified this problem:

No changes other than bringing things up to date.

Hey, I'm trying to make a scenario for switzerland and I have produced a height map. However the palette is not in the correct order. For some reason Paint Shop Pro 9 keeps changing the palette order when saving the png file.

What software can I use to get the palette order right (as in reorder the palette from darker to lighter).

MSpaint?

Yeah, this one caught me out too. When you bring up the save dialog, select PNG format, and click Options. You will see that Psp has "optimise palette" selected by default. This is what is scrambling the palette. Select "Non-optimised palette". Solved problem for me.

Any updates LordOfThePigs? It'd be wicked to have an accurate scenario of Switzerland to go with the Swiss Set!

Any how, do you still check on progress with us?

PSP9 is fine. If you are 100% sure your palette is in ascending brightness order, then you can simply go "Greyscale", followed by "Reduce colours to 16". Then save as PNG (with non-optimised palette).

Here is a really long overdue update... I just finished final exams and finally have some time.

Changes:
Works with any color depth - Indexed, Grayscale, and 24-bit RGB color PNGs will work now. Also, any transparency/16-bit color is discarded, so pretty much any valid PNG file should load just fine. All color is converted to grayscale, ranging from black at height 0 (water) to white at height 15 (highest mountain). So no more messing around with problematic palettes!

The "Are you sure you want to load...?" dialog was removed since it's possible to close the file browser to cancel.

Future plans:
A separate window showing the loaded image and map preview, with adjustment options (probably similar to SV0 Creator's interface).
Maybe eventually something like the map generator could use it as well...

Let me know if there are any problems... so far I've tested it on OS X and Win2K, though there aren't any OS-specific changes. Also, I'm open to suggestions for the map load window interface and features... it's all still in the planning stages.

Edit: Some small bug fixes
Fixed incorrect loading of 4-bit images, slightly modified the error messages, and changed the grayscale conversion to use a bit shift instead of division (probably almost no difference either way).

Hello!

How to??

I have created a Denmark.scn in pngmap10_win_158 (thank you for the last 16-bit interpreter - it works!) and wanted to run it on OTTD 0.4.0.1 - All I get is a GAME LOAD FAILED.

QUESTION:
My scenario is a 2048*2048, and rich on detail - can I count on the possibility of in the future running it on official releases, or shall I forget the hole thing? I would very much like to share this scenario with everyone else when I'm finished working on it.

If the developer team likes it, and it has a lot of features, it may be added. However, there s one Denmark map already

I realize that there is allready a Denmark scenario. I think its 256*256 which I find TOO small for a game that will last you more than 5 hours.

Is there a list of developers-accepted SCN, and are there any "official" guidelines for creating SCNs?

Make them so good that I like it

Frankly, scenario must be working in a pure nightly, and have features. No empty flatlands

Oh my god, this is so cool... and easy!

I think I am going to create an Middle Earth, or a portion of it, have not seen it here, might be fun...

But first some testing...

Big hooray for cccp...

It seems to me that this thread belongs in OpenTTD Development? Maybe that's just me, though.

Second, unsurprisingly enough, in 958 revisions, attrition has, in fact, caught up to us. It applies and compiles just fine; but it has a habit of segfaulting at inappropriate times.

It's bedtime now, though. I'll look into it sometime in the next 24 hours, assuming no one beats me too it.

DaleStan · Post by **DaleStan** » 07 Apr 2006 18:44

And it seems to work now.

DaleStan · Post by **DaleStan** » 11 Apr 2006 08:01

I fixed it to compile without WITH_PNG once before, so surely it'll still work, right? No. Of course not.

Fixed.

The changes here are to properly wrap the SLD_PNG bits in main_gui.c with an #ifdef WITH_PNG/#endif, and to add a break; to the relevant case.

BTW: The change in PNGMap 11 was to assert that edge tiles were MP_VOIDs instead of trying to set them to MP_CLEARs.

i appreciate all the programming effort that has gone into this - this thing rocks.

if anyone is interested nasa has heightmaps here:

im sure somewhere nasa has other planets too
