<h1> SDL_stretch - <em>Stretch Functions For SDL</em> </h2>
<p> </p>
<p><big><blockquote><em>
While hacking on UAE (the unix amiga emulator) I did develop a few
stretching routines. I have been asking on the SDL mailing list for any
prior art but it seems that no one did wrap such routines into a
library part that can be reused everywhere. Other projects are
just game SDKs which tend to wrap such routines it into their
own framework - instead of using vanilla SDL surface. Also, there
are only rare pieces of assembler optimized routines. I took some
of these as hints and created my own set of highly optimized routines
pumped up with assembler - stretch-and-blit routines for SDL on steroids.
</em></big></blockquote></p>
<b>News:</b>
<blockquote>In version 0.3.0 the assembly code generation for i386 was extended to
support also x86_64 (amd64) with native code. However the support did require a
little incompatibility as all 64bit unices are set on a non-executeable data (and
heap) segment such that an allocation with memalign/mprotect must be used now.</blockquote>
<blockquote>Additionally the traditional code generation does also know about an
interpreted mode for platforms that are not yet support by native machine code
definitions. That should make build servers happy although it's not an
optimal solution - it can not be as quite as fast as on-demand machine code.</blockquote>
<blockquote>Last not least, there is a new example program that is derived from
the SDL parallax-2 demo (http://olofson.net/examples.html). The SOFTSTRETCH-ifdefs
will guide you how to make your SDL window resizeable with the help of SDL_stretch.
That demo program might also help with porting the software to other CPU types.</blockquote>
