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

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

```
func draw(in rect: NSRect, from fromRect: NSRect, operation op: NSCompositingOperation, fraction delta: CGFloat)
```

## Parameters

`rect`

The rectangle in which to draw the image, specified in the current coordinate system.

`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. 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

If the `srcRect` and `dstRect` rectangles have different sizes, the source portion of the image is scaled to fit the specified destination rectangle. 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.
