canInit(with:)
Returns a Boolean value that indicates whether the image representation can initialize itself from the specified data.
Declaration
class func canInit(with data: Data) -> BoolParameters
- data:
The image data.
Return Value
true if the receiver understands the format of the specified data and can use it to initialize itself; otherwise, false.
Discussion
This method should be overridden by subclasses. Note that this method does not need to do a comprehensive check of the image data; it should return false only if it knows it cannot initialize itself from the data.
