Well, here's one way:

int color[16][16] = {
  { 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000,
    0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000, 0x0000 },
  { 0x1111, 0x1111, 0x1111, 0x1111, 0x1111, 0x1111, 0x1111, 0x1111,
    ... },
   ...
 };

Icky, eh?

You could do something like this instead:

void SetDithColor(int x)
{
  int patt[16], i;
  x *= 0x1111;
  for(i=0; i<16; i++)
      patt[i] = x;
  SetPenPat(patt);
}

(Not tested, but looks okay.)


>2)  How do I define an icon (in the format used for DrawIcon()) in C?

You can do a fairly straightforward translation of your Pascal code into
C; of you can use an icon editor to generate the code.  (I know my DIcEd
will "Save As Source" for "APW C"; other icon editors may, too.)  DIcEd
generates something like this for you (in a text file):

static char Icon1[] = {
  0x00, 0x00, 0x80, ... /* lots o' bytes */
}

which you can just cut and paste it into your code.  The dialog box says
APW C, but it's just a generic "static char" declaration, so it'll work
just as well with ORCA/C.
