# 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 are specified in the image’s own coordinate system. If you pass in `NSZeroRect`, the entire image is drawn.

`op`

The compositing operation to use when drawing the image. See the [`NSCompositingOperation`](/documentation/AppKit/NSCompositingOperation) constants.

`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.

Unlike the [`compositeToPoint:fromRect:operation:`](/documentation/AppKit/NSImage/compositeToPoint:fromRect:operation:) and  [`compositeToPoint:fromRect:operation:fraction:`](/documentation/AppKit/NSImage/compositeToPoint:fromRect:operation:fraction:) methods, this method checks the rectangle you pass to the `srcRect` parameter and makes sure it does not lie outside the image bounds.

## See Also

[`-  dissolveToPoint:fraction:`](/documentation/AppKit/NSImage/dissolveToPoint:fraction:)

Composites the entire image to the specified location using the source-over operator.
