---+!! Rockbox 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. |*question*|*answer*| |How many colors|2 (support for multicolor bitmaps is still distant)| |How big|Individual for each image. (See source code.)| |What format|1 bit BMP converts easily to the internal rockbox format with the bmp2rb tool| |What colors|black and white| |Where are the images stored?|They are stored as arrays in Rockbox source code.| ---+++ 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 colors 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* Once you've created your fantastic logo you save it as a *.BMP, use bmp2rb and paste the new code over the old. *Note!!!!* The colors might get inverted when converting, so black becomes white. Remember that when creating your logo!
