# draw(at:from:operation:fraction:)

Draws all or part of the image at the specified point in the current coordinate system.

```
func draw(at point: NSPoint, from fromRect: NSRect, operation op: NSCompositingOperation, fraction delta: CGFloat)
```

## Parameters

`point`

The location in the current coordinate system at which to draw the image.

`fromRect`

The source rectangle specifying the portion of the image you want to draw. The coordinates of this rectangle must be specified using the image’s own coordinate system.

`op`

The compositing operation to use when drawing the image. For details, see <doc://com.apple.documentation/documentation/AppKit/NSCompositingOperation>.

`delta`

The opacity of the image, specified as a value from `0.0` to `1.0`. Specifying a value of `0.0` draws the image as fully transparent while a value of `1.0` draws the image as fully opaque. Values greater than `1.0` are interpreted as `1.0`.

## Discussion

The image content is drawn at its current resolution and is not scaled unless the CTM of the current coordinate system itself contains a scaling factor. The image is otherwise positioned and oriented using the current coordinate system.
