    C# resources and question about C++, and what data is possible to save into a file

    hello.

    I've been working a bit with C# to make a GUI for an editor of mine, now I need a rectangle tool that's transparent and fully controllable by the user, much like the crop tool in Photoshop and The Gimp, can anyone link me to a resource, since I don't wanna learn C# :S

    Also, I did make a stupid approach, I didn't check how compatible C# is with C++. I wanna make a console app that takes certain parameters, if not direct data (depending on how well C# and C++ work together) and then this console app creates my file with the specified data... Is this possible?

    Then last but not least, I wanna make a file format which holds a texture, (meaning .png, .dds, .tga (all these support transparency)), and then I need it to hold some other data too, like some vectors (x and y coordinates) and maybe something else, I ain't sure, but those in the first place... Is this possible?

    Hope I'm clear and thanks in advance!

    Yes, they can work with each other.
    But how well? That is always the question when working with different languages, so saying the answer to that is a difficult task.

    Of course it's possible.
    It's dead easy in C++, but I don't know what options C# offers for reading files, so saying how also becomes a difficult task.

    The C# to C++ thing can be a little tricky. I made a converter that converted a bmp file to my own format (adding an alpha-channel and some stuff like that) and what i found out is that you have to be very careful to make sure you choose the correct data-types in C# for them to match in C++ (a char in C# is a 16-bit Unicode character for instance).

    Read up on the different inbuilt data-types in C# and find which ones map to an inbuilt data-type in C++ and you should be good.

    ... I'll have my man Mossa do it, since he's interested in C# and I'm definetly not xP
    Also, to make a file format, I will have to make a writer and reader 'SDK', right?
    Is it possible to get the code itself from a .dds, .png and .tga file, or will I have to use a link to the image location?

    A file format is exactly what you want it to be.
    For example, in some code you might write like:
    Code:
    struct mystruct { /* ... */ };
    mystruct foo;
    fwrite(&foo, sizeof(foo), 1, f);
    Now you have a file format.
    Getting it to work with C# is the only real problem.

    PNG allows arbitrary data blocks, so using libpng for reading and writing PNG data might be a good approach.
    All the buzzt!

    you can also use DevIL to read in different image-formats easily. It supports reading png, tga and dds files and is quite easy to use once you get the hang of how it works.

    Ok, DevIL sounds like the thing... Still, working with C# is more than horrible >.<
    I think Imma make the console version in C++, then get the GUI working based on that...
