# NSBitmapImageRep.Format

Constants that represent bitmap component formats.

## Declaration

```swift
struct Format
```

## Overview

Overview You can combine these values and pass them to the  init(bitmapDataPlanes:pixelsWide:pixelsHigh:bitsPerSample:samplesPerPixel:hasAlpha:isPlanar:colorSpaceName:bitmapFormat:bytesPerRow:bitsPerPixel:) method as the bitmap format. You can access them later in the  bitmapFormat property.
