Struct Tone 

pub struct Tone {
    pub lines: f64,
    pub resolution: f64,
    pub angle: f64,
    pub shape: u32,
    pub mode: u32,
    pub density: f64,
    pub unknown: (u32, u32),
}

Settings of a switched-on tone effect.

Fields

lines: f64

Lines per inch.

resolution: f64

The resolution lines refers to (dpi).

angle: f64

Screen angle in degrees.

shape: u32

Dot shape: 1 round, 2 square, 4 lines.

mode: u32

Where the density comes from: 0 the image, 2 density.

density: f64

The fixed density, 0..1.

unknown: (u32, u32)

Words 13 and 14, not decoded (0 in most layers).

Implementations

impl Tone

pub fn parse(section: &[u8]) -> Option<Tone>

The settings when the section switches the tone on.

pub fn is_approximate(&self) -> bool

Whether the drawing of these settings is not known exactly: other shapes are drawn as round dots, other modes take the density from the image, and lines matched only at 0° (96 %).

pub fn draw(&self, image: &RgbaImage, origin: (i64, i64)) -> RgbaImage

Draw image (top-left at canvas origin, full size) as the tone.
