fill_extents


Description:

public void fill_extents (out double x1, out double y1, out double x2, out double y2)

Example: Fill (II):

public static int main (string[] args) {
// Create a context:
Cairo.ImageSurface surface = new Cairo.ImageSurface (Cairo.Format.ARGB32, 125, 200);
Cairo.Context context = new Cairo.Context (surface);
context.set_source_rgba (1, 0, 0, 1);
context.set_line_width (1);

// Triangle:
double x1;
double y1;
double x2;
double y2;

context.move_to (25, 25);
context.rel_line_to (75, 75);
context.rel_line_to (-75, 75);
context.close_path ();

// Output: ``true``
bool tmp = context.in_fill (50, 60);
print (@"$tmp\n");

// Output: ``false``
tmp = context.in_fill (10, 10);
print (@"$tmp\n");

// Output: ``25.000000, 25.000000, 100.000000, 175.000000
context.fill_extents (out x1, out y1, out x2, out y2);
print ("%f, %f, %f, %f\n", x1, y1, x2, y2);
context.fill ();


// point (50, 50)
context.set_source_rgba (0, 0, 0, 1);
context.arc (50, 60, 2, 0, 2*Math.PI);
context.fill ();

// point (10, 10)
context.arc (10, 10, 2, 0, 2*Math.PI);
context.fill ();

// Extents-box:
context.rectangle (x1, y1, x2, y2);
context.stroke ();

// Save the image:
surface.write_to_png ("img.png");

return 0;
