Rockbox (iRiver H100 Series) Graphical UI Design

Well i've decided i want to create my own theme and edit the graphics (ala boot logo/usb logo). With the help of t0mas and several other fellows on the IRC channel i've managed to learn how to use the CVS and devkit within a few hours, so give me a break if i get some things wrong here.

I actually managed to create a logo (test logo) and replace the USB logo in screens.c, but after looking at it in the simulater its come out very wrong. There could be a 100 reasons why its not working, so i'm going to start by asking exactly WHAT specifications rockbox needs the bmp's to be in.

Eg.

How many colors: ?

How big: ? (It seems to be individual for each graphic)

What format: ? (Indexed? Grey Scale?)

What colors: ? (I'm pretty sure i have the correct colors in photoshop setup)

Also, where are all the logos stored? I've found most, but i can't find the main 'Rockbox' logo.

Creating Logo's In PhotoShop?

First, get the exact size of the logo you are going to replace by finding it in the mass of *.c source files, its width and length are provided in there along with the code you will soon be replacing.

Hop into PS and correct the image size.

Go to Image>Mode and select Bitmap, leave the options that come up and push ok.

Your set, simply stick to using the following supported colors:

#FFFFFF

#000000

The following color are ment to be the colors that will be supported once 4-bit greyscale completely works.

#6E6E6E << Doesn't work yet

#DCDCDC << Doesn't work yet

Ok, i've been told only 2 colors (black and white) work right now so that would explain a few things. I made a 2 color logo and put it in, and its come up with this: * untitled1copy2un.jpg:
The white 'USB' logo is the original picture. It seems to me i'm having problems turning the .bmp into the rockbox graphic code. I think its the format i save the pictures as.

It'd be really great if someone could help me here. What format do the BMPs need to be in?

Ok, i got it working. It was indeed the wrong format i was using. Now the problem is, when rockbox finally get the 4 color greyscale working everything will change. So now all i can do, after all this, is wait. :P
