Converting and using graphics to .c

[Zettablade]

I've heard this is possible. I've converted a .bmp to a .c file, but I didn't know how to use it. What tool can convert a .png to a .c file. Then how can I use it in my program?

Erm.
.c isn't an image format

I know, but I'm still wanna know how this is done. Or at least how to encrypt images.

Ah, I got you now.
Sorry, I can't help you with that.

.c isn't an image format, it is a source code. Try doing a put pixel in a loop to the screen using the picture source array.

There's a tool that comes with the toolchain, bin2o I think it is. Try it out. Shine also had a Java program that did it. I included it with my Snakman releases (check out version .3, it has it integrated into the Makefile)

That will convert BMP to raw C code.
When I did that, I used pg to display the images.

As Yeldarb mentioned, bin2o is the tool you want, it comes with the PSPSDK.

It converts your RAW file to an .o file, which you can add to your makefile which will then be added to your eboot.

the snakmanv_3 doesn't wanna load for me. But that's pretty much what I need for now.

Edit: got it now. it's very nice, I think I'm gonna figure it out and start using it. Yes, i do know this uses more memory, but it's to protect files an such.

The gimp can do it too, will save any format to .c
A determined person can still edit your graphics with a hex editor however

[SG57]

Yes, its quite easy to convert .C back to its image... But you have to hex edit the eboot and basically rip the 'image' out of it...

[framerate]

this was very common for early PSP work (my first RPG engine used this technique). but now I really recommend just using libpng or SDL or something to load your images in.. it's way cleaner (in my opinion at least...)

[Zettablade]

Hmm, the main downide to this is that .raw can't be transparent, and neither can bmp. Well, if anyone knows how to keep the transparency, let me know.

[Yeldarb]

You can't keep an alpha channel I don't think, but you can designate a color as transparent. (If you're writing your own blitting funtion that is; I'm not sure about how the different libraries handle transparency)

[danzel]

PNG has transparency.
Check out libpng from the ps2dev svn and there is an example incliuded to show you how to use it.

yes, but this isn't png.

But yeldarb, that is an awsome idea. I think I'll look into it later after i get all my animations working.
Also, could you use a spritesheet after converting it to .c?

[Yeldarb]

I'm sure you could, you just have to write your own function to do it. Not too difficult.

Start -> All Programs -> Accessories -> Paint
File -> Open -> [open bmp]
File -> Save As... -> Save as type: PNG

lol
your funny. I'd never even open paint. Photoshop is far too good.
But in the end, even if it was a png, it would still be converted to a raw, and that would make the bg white. But as me an Yeldarb were just talking about, I'de have to make my own blitting function and designate a color to be transparent. very complicated stuffs.

Why do you want it to be a raw image??
Just use PNG, it has no color loss, and is highly compressed. AND supports transparentcy and you can easily handle it with libpng.
Yeldarb made a great image tutorial that uses libpng:

[Yeldarb]

The whole thread is about how to convert an image to RAW and embed it into his program

[Zettablade]

have you read this topic? It's discussing converting images into a c file so you can encrypt the images within the EBOOT. png is awsome, but for an image to be converted into a c file, it must first be converted into a raw!
Edit - Yeldarb beat me to it.

[Fanjita]

Actually you could still embed PNGs in your EBOOT, there's no need to decode them to raw bitmaps first. And that way, you'd take advantage of the extra file compression too.

The only downside is you have to do a bit of messing with custom read functions in libpng, which can be confusing for a lot of people, especially with a lack of good examples on the web. But it's not all that hard.

I understand that, but I dont think he knows about how to use PNG. I mean, he is new, and probably doesnt know much. Using PNGs are a lot simpler to both implement the code and create the images, as well as transparencies.
