Legacy:Image/zoomBlit

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.

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();
}

Notes

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