No, it's just that for nSDL, there should be this before pixel data :
Code: [Select]
0x2a01, width, height, 0x0000,

So 0x0000 as transparent color means no transparency?
Nope, it means that nSDL will load that, then you'll have to set the transparency in your program, for each sprite, nSDL will probably put it the way we do instead of that 0x0000 and then you'll have transparency.

So, ConvertImg should work now, it supports all three formats (nSDL, nGL and n2DLib) and two of them are of course untested.
It fully supports every file format Qt supports, if it's a file with transparency the transparency will be replaced by a unique new color, the lowest color that isn't already somewhere in the image. Link to the windows version: https://github.com/Vogtinator/ConvertImg/releases/tag/v0.9
For other OSs you need to compile it yourself: "qmake . && make && sudo make install"

Okay so I tried this with --format=n2dlib, and it doesn't set the correct transparency value. Actually, it doesn't set any value at all, it keeps being 0x0. nSDL format works fine though, thanks for this =]

What I'm asking is : can I use it in my makefile ? Scriptable = usable programmatically.

Oh sorry. Actually it can't be used in another way.

Code: [Select]
ConvertImg --format=[n2dlib | ngl | nsdl] in [out]

Oh cool. I'll see how it works out in my setup. That script I made was actually designed with a specific purpose in mind. :P

Well, 0x0 can be the correct value. I just tried it and for a small picture with just a black pixel in the center it works and picks the next available one.

I'm using it in my Makefiles and it works without problems: ./ConvertImg --format=ngl blockselection.png blockselection.h

It's not available. I use 0x0000 in my image. Also, personally I would rather want the tool to use the top-left corner pixel as transparent color, because all of my images I ever used did that.

Ah, but you make a .h for each sprite ? I >> all my sprites into a .c and let makeheaders work its magic, then link the .o with the tns.

Hm, could you send me your test picture then?

Trust me, it's much easier to use proper transparency and not worry about it. PNG FTW!

I used the little image I did in 3.14 seconds to demonstrate n2DLib's drawSpriteRotated function. Attached ; it gave me this :
Code: [Select]

};
As you can see, I usually use 0xf81f as transparent color.

Well yes, but no PNG in n2dlib.
