Homebrew Converting .png to .bin and .h

[mashers]

When I build home brew launcher from source, I can put png files which have been converted to .bin into the data directory, and it gets compiled into the product and the object can be referenced through a header file.

I'm currently using a web based tool to convert the image to the .bin file, but I want to be able to display png images from SD without having to convert them first. Does anybody know what format the .bin file is in, and if there is a method of doing the same thing in C?

From here:

the image is clockwise rotated by 90 degrees and its B and R channels are swapped. The first operation is done because the 3DS screens are actually portrait screens rotated by 90 degrees (in a counter-clockwise direction), while the second one is done because the 3DS screens' framebuffers have a BGR888 color format, by default

Now you figure out how to do that because I don't know C or anything

Nevermind I misunderstood you xD

Portal3ds has code to load png files from sd. https://github.com/smealum/portal3DS/tree/master/source/gfx

@elhobbs
Are you referring to lodepng.c?

I think hbl does that to optimize and embed its graphics thoughh

yes

Thanks. Looking into it, it seems to be a standalone PNG encoding/decoding function. If it can decode it into the right type of data then it could work. Thanks!

Sure, and I don't intend to do this for any built in graphics such as the UI. I want to give the option of adding a high resolution icon for the top screen, and I don't want the user to have to convert to .bin format in advance.

I don't know if it's to late but you can use sfillib to load images

Thanks- I'm still looking into options for PNG loading, so I'll look it this library too.
