miniview

MiniView is a bare-bones image viewer intended to be used during development and testing. MiniView can be called as binary from the CLI, and used as a Rust library.

To see what it can do, and whether it would fit your purpose, please see:

• Use from the cli
• Use as library
  • Documentation: docs.rs

MiniView is not intended to be used as your primary image viewer. For that purpose, I would recommend Emulsion.

Install

Binary installation

With cargo install: cargo install --force miniview

Pre-build binary: see releases

Add library dependency

Run cargo add miniview with cargo-edit, or add miniview as a dependency to your Cargo.toml:

miniview = "*" # replace `*` with the latest version

Usage

Instructions for library use

use miniview::config::ConfigBuilder;
use std::time::Duration;

fn main() {
    let config =
        ConfigBuilder::from_path(concat!(env!("CARGO_MANIFEST_DIR"), "/resources/plant.jpg"))
            .set_fullscreen(true)
            .set_lazy_window(false)
            .build();

    let controls = MiniView::show(config).expect("unable to create miniview");

    // do some important other work!
    std::thread::sleep(Duration::from_millis(1000));

    let closed = controls.close();
    assert!(closed.is_ok());
}

Backends

MiniView supports two backends: piston-window and pixels. You can switch between backends on compile time. This requires setting Cargo features. The piston-window backend can be enabled using the backend_piston_window feature, and the pixels backend can be enabled using the backend_pixels feature.

The default backend is pixels. This backend will be used if no-default-features is not specified. Note that the default backend is not available on MacOS.

The next sections provide examples, on how to enable each backend. Only one backend should be enabled at a time.

backend: piston-window

Platform support

Configuration examples

When building MiniView, the piston-window backend can be used by compiling with:

cargo run --no-default-features --features backend_piston_window 

When using MiniView as a library, you can use:

[dependencies.miniview]
version = "*" # replace `*` with the latest version
default-features = false 
features = ["backend_piston_window"]

or

[dependencies]
miniview = { version = "*", default-features = false, features = ["backend_piston_window"] }

NB: replace * in version = "*" with any supported version.
