# bytesPerRow

The minimum number of bytes required to specify a scan line in each data plane.

```
var bytesPerRow: Int { get }
```

## Discussion

A scan line is a single row of pixels spanning the width of the image. If not explicitly set to another value (in [`init(bitmapDataPlanes:pixelsWide:pixelsHigh:bitsPerSample:samplesPerPixel:hasAlpha:isPlanar:colorSpaceName:bytesPerRow:bitsPerPixel:)`](/documentation/AppKit/NSBitmapImageRep/init(bitmapDataPlanes:pixelsWide:pixelsHigh:bitsPerSample:samplesPerPixel:hasAlpha:isPlanar:colorSpaceName:bytesPerRow:bitsPerPixel:))), this number will be figured from the width of the image, the number of bits per sample, and, if the data is in a meshed configuration, the number of samples per pixel. It can be set to another value to indicate that each row of data is aligned on word or other boundaries.
