Created page with "Draw the image onto the screen with zooming. =Usage= ::''image''.zoomBlit(''x'', ''y'', ''factor''); * '''image''' Sphere Image object. The image to draw on screen. * ''..."

New page

Draw the image onto the screen with zooming.

=Usage=
::''image''.zoomBlit(''x'', ''y'', ''factor'');

* '''image''' Sphere [[Image]] object. The image to draw on screen.
* '''x''' number. The x coordinate of the top-left corner of the drawn image.
* '''y''' number. The y coordinate of the top-left corner of the drawn image.
* '''factor''' number, floating-point. The amount of zooming applied. factor == 1 causes no zoom, 0 < factor < 1 causes the image to shrink, factor > 1 causes the image to enlarge.

=Examples=

This simple game will take an image and zoom it so that it is stretched to fit the screen.

<syntaxhighlight>
function game()
{
var w = GetScreenWidth();
var h = GetScreenHeight();
var img = LoadImage("my_test_image.png");

// Calculate by how much to zoom.
var factor = Math.min(w / img.width, h / img.height);

img.zoomBlit(0, 0, factor);

FlipScreen();
GetKey();
}

</syntaxhighlight>

=Notes=

* [[Image.transformBlit()]] can also be used to achieve zooming, by picking the corner points manually.
