init(platformColorSpaceRef:)

Declaration

init?(platformColorSpaceRef ref: UnsafeRawPointer)

Parameters

• ref:

  A generic pointer to a platform-specific color space. In macOS, pass a ColorSyncProfileRef, which is a ColorSync profile. Quartz uses this pointer (and the underlying information) only during the function call.

Return Value

A new color space, or NULL if unsuccessful. In Objective-C, you’re responsible for releasing this object by calling CGColorSpaceRelease.

Discussion

Colors in a device-dependent color space are not transformed or otherwise modified when displayed on an output device — that is, there is no attempt to maintain the visual appearance of a color. As a consequence, colors in a device color space often appear different when displayed on different output devices. For this reason, device color spaces are not recommended when color preservation is important.
