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

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

## Declaration

```swift
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

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.
