It's my first SO question, so please be gentle. :)
I'm not a programming expert. I've got a program I'm playing with. It came with some BMP files. I still have the BMP files, but I'm converting them to C code instead. Currently, I'm loading them thusly:
static char bits[] = {
0xff,0xff,0xff,0xff,0xff,0xab,0xaa,0x5a,0x55,0xd5,0x55,0x55,0xb5,0xaa,0xaa,
0xab,0xaa,0x5a,0x55,0xd5,0x55,0x55,0xb5,0xaa,0xaa,0xab,0xaa,0x5a,0x55,0xd5,
[blah blah blah]
0xff,0xff,0xff,0xff,0xff};
walls.pixmap = XCreateBitmapFromData(dpy,DefaultRootWindow(dpy),bits,40,40);
Each of the characters that is greater than 0x80 is generating this warning:
bitmaps.c:38: warning: overflow in implicit constant conversion
So I tried changing my definition to
static unsigned char bits[] = {
but that displays a new warning:
bitmaps.c:31: warning: pointer targets in passing argument 3 of 'XCreateBitmapFromData' differ in signedness
/usr/include/X11/Xlib.h:1607: note: expected 'const char *' but argument is of type 'unsigned char *'
Is there a way to load bitmaps that will compile without warnings? Should I just accept that warnings will always appear? Should I be doing something different since I have the raw BMP files anyway?
Thanks.
