SDL_Surface
A structure that contains a collection of pixels used in software blitting.
Data Fields
Uint32 |
flags |
(internal use) |
format |
the format of the pixels stored in the surface; see SDL_PixelFormat for details (read-only) |
|
int |
w, h |
the width and height in pixels (read-only) |
int |
pitch |
the length of a row of pixels in bytes (read-only) |
void* |
pixels |
the pointer to the actual pixel data; see Remarks for details (read-write) |
void* |
userdata |
an arbitrary pointer you can set (read-write) |
int |
locked |
used for surfaces that require locking (internal use) |
void* |
lock_data |
used for surfaces that require locking (internal use) |
clip_rect |
an SDL_Rect structure used to clip blits to the surface which can be set by SDL_SetClipRect() (read-only) |
|
SDL_BlitMap* |
map |
info for fast blit mapping to other surfaces (internal use) |
int |
refcount |
reference count that can be incremented by the application |
Code Examples

Remarks
With most surfaces you can access the pixels directly. Surfaces that have been optimized with SDL_SetSurfaceRLE() should be locked with SDL_LockSurface() before accessing pixels. When you are done you should call SDL_UnlockSurface() before blitting.
