init(data:scale:)
Initializes and returns the image object with the specified data and scale factor.
Declaration
init?(data: Data, scale: CGFloat)Parameters
- data:
The data object containing the image data.
- scale:
The scale factor to assume when interpreting the image data. Applying a scale factor of 1.0 results in an image whose size matches the pixel-based dimensions of the image. Applying a different scale factor changes the size of the image as reported by the Size property.
Return Value
An initialized UIImage object, or nil if the method could not initialize the image from the specified data.
Discussion
The data in the data parameter must be formatted to match the file format of one of the system’s supported image types.
