Public Class Methods

new(*args) click to toggle source

Returns a new Imlib2::Color::RgbaColor.

Examples:

r, g, b, a = 255, 0, 0, 255
border = Imlib2::Color::RgbaColor.new r, g, b, a

values = [255, 0, 0, 255]
border = Imlib2::Color::RgbaColor.new values
VALUE rgba_color_new(int argc, VALUE *argv, VALUE klass) {
  Imlib_Color *color;
  VALUE c_o;
  
  color = malloc(sizeof(Imlib_Color));
  memset(color, 0, sizeof(Imlib_Color));

  c_o = Data_Wrap_Struct(klass, 0, free, color);
  rb_obj_call_init(c_o, argc, argv);

  return c_o;
}
