32bit Graphics Extra Zoom Patch

[GeekToo]

OK, here a first experimental version of the CC algorithm provided by Zephyris. It's able to show all the company colours in different hue's, difference in brightness (so eg blue and lightblue) are not yet implemented.
I'm providing it here, so you can comment on the saturation value, that I picked (it's hardcoded for now (in 32bpp-base.hpp if you want to tweak it), and the CC mapping in general.
My first impression is that it indeed loses some of the hue and saturation gradients, but that the mapping of the CC's is very good, the red trucks now really look red, independent of the original sprites colour).
It's also not optimized (apart from using only int's iso floats) in any way, first I want to get the algorithm right.

So play around a little with it, and let me know what you think.

Unfortunately I don't know the technicalities of how it works, but it appears to be displaying at least the general colours correctly, I assume cream and white requires the brightness differences to display correctly? If anyone needs a binary compiled for Windows 32/64, let me know and I'll put them up.

That would be most welcome. I don't have MinGW etc. installed anymore.

I'm using windows, so a Windows binary would be very welcome.

Great to see the 32bpp cc problem (mostly) solved

Ok here are the two, I have tested them so they should have the correct files etc.

Windows 32-bit
Windows 64-bit

Thanks I'm using Windows Vista 32bit and it works fine.

Some screenshots. I think that the saturation should be modified less, only the half than the current algorithm.

This is because some areas looks too oversaturated, and sometimes there are some strange borders. Note that stations have a wrong CC mask.

[maquinista]

More screenshots. Look at the lines in the water depot. Also, the top of one building looks strange. I think that It could look better with less saturation.

[GeekToo]

Thanks Maquinista,
I guess you're right, the saturation is rather high, I'll do some experiments with different settings in the near future.

Just a suggestion: user-configurable saturation (for testing)?

Is that feasible?

Not... but I can try some screenshots modified in GIMP to test different saturation levels.

The problem is that the original algorith don't modify the saturation, and the new algorthim modifes it a lot.

also, (i dont know whether this was supposed to be fixed )
white is still grey!

[Zephyris]

What saturation is being used? In my tests anything over 0.8 (out of 1) was starting to look very bright and cartoony...

[GeekToo]

Zephyris, it's 175 (out of 256) which is ~0.68 out of 1.

Lord Aro, please read my post accompanying the diff, especially the part of lightblue and blue, and then ask yourself how that would translate to white and gray.

[Zephyris]

Maybe try lowering the brightness slightly too... Looking at histograms of the screenshots they are generally quite bright, lowering the brightness of the CC could help it seem less cartoony.

[maquinista]

White could be made with the highest value of the RGB values (this is like the HSV algorithm).

For example:

24,60,160 --> white --> 160,160,160
24,60,160 --> gray --> 81,81,81

If this algorithm for white increases too much the brightness, the final value could be added to the value of gray, and take the half of this value. Example 24,60,160 --> white --> 120,120,120.

Is there any way someone could make a new win32 binary with this Patch and CargoDist? I really like this and CargoDist and I hate to only be able to play one.

[petert]

I tried, but there were too many failed hunks, and compiling did not go well.

Aw, that sucks butt, I wonder how one would compile two patches together in the same binary : \
