CRV?ADER//KY proudly presents…SDL_Buffer 
SDL_Buffer is a small helper library intended to be used with a image
viewer or analogous
applications, where images are loaded from files and then resized
several times.
Its main parts are the SDL_Buffer structure, containing both the
original and the zoomed
surface, and the SDL_BufferResize function, that changes the zoom of the
surface so that it
fits inside a given square (while mantaining aspect ratio).
Also features:
- a SDL_IntelliResize structure to pass to SDL_BufferResize, to do an
"intelligent" resize
(i.e. don’t resize if the zoomed surface would be between 95% and
102% of the original)
instead of a “dumb” one.
- automatic screen centering
- image is not resized if scale = 1
- a SDL_BufferDisplay function, that blits a SDL_Buffer to screen and
(optionally) fills
the remaining space with a given color
- a multi-thread facility to pre-buffer (load and resize) a image in
background
For API documentation, please refer to SDL_buffer.h

Stay tuned for the incoming full application, SDLSee.–

“I worry about my child and the Internet all the time, even though she’s
too young to have logged on yet. Here’s what I worry about. I worry that
10 or 15 years from now, she will come to me and say: ‘Daddy, where
were you when they took freedom of the press away from the Internet?’”
