Iso Book code conversion

When in doubt, read the SDL docs. It contains information on how to get surface details. Here is brief entry from the SDL_Surface structure explanation:

SDL_Surface -- Graphical Surface Structure
Structure Definition

typedef struct SDL_Surface {
Uint32 flags; /* Read-only */
SDL_PixelFormat *format; /* Read-only */
int w, h; /* Read-only */
Uint16 pitch; /* Read-only */
void *pixels; /* Read-write */

/* clipping information */
SDL_Rect clip_rect; /* Read-only */

/* Reference count -- used when freeing surface */
int refcount; /* Read-mostly */

/* This structure also contains private fields not shown here */
} SDL_Surface;

Structure Data

flags Surface flags
format Pixel format
w, h Width and height of the surface
pitch Length of a surface scanline in bytes
pixels Pointer to the actual pixel data
clip_rect surface clip rectangle

Incidently, on Windows machines, SDL is simply a wrapper for DirectX 5. So I don''t know if you will be able do everyting that is in that book.

I was hoping there was a function that got the surface details, but thank you for pointing that out, this will help a lot!
