Struct WatermarkInput 

pub struct WatermarkInput {
    pub image: Artifact,
    pub position: Position,
    pub opacity: u8,
    pub margin: u32,
}

A watermark image to composite onto the output.

The watermark is alpha-composited onto the main image after all other transforms (resize, blur) and before encoding.

use truss::{Artifact, ArtifactMetadata, MediaType, Position, WatermarkInput};

let wm = WatermarkInput {
    image: Artifact::new(vec![0], MediaType::Png, ArtifactMetadata::default()),
    position: Position::BottomRight,
    opacity: 50,
    margin: 10,
};
assert_eq!(wm.opacity, 50);

Fields

image: Artifact

The watermark image (already classified via sniff_artifact).

position: Position

Where to place the watermark on the main image.

opacity: u8

Opacity of the watermark (1–100). Default: 50.

margin: u32

Margin in pixels from the nearest edge. Default: 10.

Trait Implementations

impl Clone for WatermarkInput

fn clone(&self) -> WatermarkInput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WatermarkInput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WatermarkInput

fn eq(&self, other: &WatermarkInput) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
