  • PNG image format.

    Portable Network Graphic (PNG) is a lossless image format, meaning no image data is lost during compression. Images in PNG format are typically larger than JPEG images, though this depends on the image content and JPEG compression quality.

    Declaration

    Swift

    public static func png() -> ImagenImageFormat

  • JPEG image format.

    Joint Photographic Experts Group (JPEG) is a lossy compression format, meaning some image data is discarded during compression. Images in JPEG format are typically larger than PNG images, though this depends on the image content and JPEG compression quality.

    Declaration

    Swift

    public static func jpeg(compressionQuality: Int? = nil) -> ImagenImageFormat

    Parameters

    compressionQuality

    The JPEG quality setting from 0 to 100, where 0 is highest level of compression (lowest image quality, smallest file size) and 100 is the lowest level of compression (highest image quality, largest file size); defaults to 75.
