Type Method

photoSettingsWithRawPixelFormatType:

Creates a photo settings object for RAW-format-only capture with the specified pixel format.

Declaration

+ (instancetype)photoSettingsWithRawPixelFormatType:(OSType)rawPixelFormatType;

Parameters

rawPixelFormatType

The Bayer RAW pixel format type to use for capture. This value must be one of the format identifiers listed in the availableRawPhotoPixelFormatTypes array of your photo capture output.

Return Value

A new photo settings object.

Discussion

Use this initializer for RAW-only capture. To capture an image in both RAW format and a processed format (such as JPEG), use the photoSettingsWithRawPixelFormatType:processedFormat: initializer instead.

Requesting RAW format capture adds requirements for other photo settings: for details, see the rawPhotoPixelFormatType property. The capture output validates these requirements when you call the capturePhotoWithSettings:delegate: method. If your settings and delegate do not meet these requirements, that method raises an exception.
