How about you not bother posting at all?

@OP - I used to use these 2 functions.

Код:

stock ShiftRGBAToABGR(color)
{
    new r, g, b, a, value = color;
    r = (value >>> 24);
    g = (value >>> 16 & 0xFF);
    b = (value >>> 8 & 0xFF);
    a = (value  & 0xFF);
    value = (a & 0xFF) | ((b & 0xFF) << 8) | ((g & 0xFF) << 16) | (r << 24);
    return value;
}

stock HexToInt(string[])
{
	if (string[0]==0) return 0;
    new i;
    new cur=1;
    new res=0;
    for (i=strlen(string);i>0;i--) {
        if (string[i-1]<58) res=res+cur*(string[i-1]-48); else res=res+cur*(string[i-1]-65+10);
        cur=cur*16;
    }
    return res;
}

A safe method to turn string into hex is to use sscanf plugin using 'x' specifier.

Код:

sscanf( string, "x", hexcol)

PHP код:



GetColor(0xFF0000FF);        //Return {FF0000}

RGB.inc

such a thing needed?
