How to load a 32-bit RGB string with a given width and height into a Pixmap in Xlib?

Question

I want to load an int string, which consists of width × height elements, which represents a 32-bit RGB value into a Pixmap in Xlib.

I've just found XReadBitmapFile(), which can read from a X Bitmap to X Pixmap, and this might not really meets my needs.

So, should I design a new function to process it? Any hints are appreciated.

Read up on XImage and associated functions, google for examples. — n. m. could be an AI, Sep 03 '14 at 17:11

void drawString::DrawString(Display *d, Drawable win, XFontStruct *fontType, int rectWidth, int rectHeight, int HAlign, int VAlign, char* fmt, unsigned long color, unsigned long textColor, Pixmap bgPixmap)
{
    GC gc;

    if( initValues->blnExitUITThread )
        return;

    if( fontType == NULL )
        return;

    unsigned short fontHeight, fontWidth, singleFontHeight;
    int x, y;
    Pixmap pixmap;
    char* token;

    initValues->trueColor = textColor;

    pixmap = XCreatePixmap(d, win, rectWidth, rectHeight, DefaultDepth(d, 0));
    gc = XCreateGC(d, pixmap, 0, NULL);
