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.

new ( -color => )

"SDL::Color::new" with the "-color" option allows one to create a new color object from a pre-existing SDL_Color*. This constructor will set the internal color state to mirror that of the specified color. This object will deallocate the color object upon completion. This is not suitable for color that exist as part of another object.

new ( -r => 0xff, -g => 0xff, -b => 0xff )

"SDL::Color::new" with the "-r,-g,-b" options will populate a new color object with the corresponding composite values.

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

"SDL::Color::new" with a SDL::Surface and a Uint32 pixel value can also be used to generate SDL::Color objects. Like as with the "-color" option "-surface,-pixel" will set the internal state to reflect the color values given the SDL::Surface's palette and color format.

r ( [ red ] )

"SDL::Color::r" sets and fetches the red component of the color object

g ( [ green ] )

"SDL::Color::g" sets and fetches the green component of the color object

b ( [ blue ] )

"SDL::Color::b" sets and fetches the blue component of the color object

pixel ()

"SDL::Color::pixel" returns the Uint32 color value of the given color in the format of the provided surface.
