NAME

SDL::Color - a SDL perl extension

SYNOPSIS

   $color = new SDL::Color ( -r => 0xde, -g => 0xad, -b =>c0 );
   $color = new SDL::Color -surface => $app, -pixel => $app->pixel($x,$y);
   $color = new SDL::Color -color => SDL::NewColor(0xff,0xaa,0xdd);
 
 

DESCRIPTION

"SDL::Color" is a wrapper for display format independent color representations, with the same interface as SDL::Color.

new ( -color => )

"SDL::Color::new" with a "-color" option will construct a new object referencing the passed SDL_Color*.

new (-r => , -g => , -b => )

"SDL::Color::new" with "-r,-g,-b" options will construct both a SDL_Color structure, and the associated object with the specified vales.

new (-pixel =>, -surface =>)

"SDL::Color::new" with "-pixel,-surface" options will generate a SDL_Color* with the r,g,b values associated with the integer value passed by "-pixel" for the given "-surface"'s format.

r ( [ red ] ), g( [ green ] ), b( [ blue ] )

"SDL::Color::r, SDL::Color::g, SDL::Color::b" are accessor methods for the red, green, and blue components respectively. The color value can be set by passing a byte value (0-255) to each function.

pixel ( surface )

"SDL::Color::pixel" takes a "SDL::Surface" object and r,g,b values, and returns the integer representation of the closest color for the given surface.
