Vello SVG viewer

This example program parses SVG files with usvg and renders them with Vello.

The rendering is extremely simplistic and does not yet support:

• group opacity
• mix-blend-modes
• clipping
• masking
• filter effects
• group background
• path visibility
• path paint order
• path shape-rendering
• embedded images
• text
• gradients
• patterns

Usage

Running the viewer without any arguments will render a built-in set of public-domain SVG images:

$ cargo run -p usvg_viewer --release

Optionally, you can pass in paths to SVG files that you want to render:

$ cargo run -p usvg_viewer --release -- [SVG FILES]

Controls

• Mouse drag-and-drop will translate the image.
• Mouse scroll wheel will zoom.
• Arrow keys switch between SVG images in the current set.
• Space resets the position and zoom of the image.
• Escape exits the program.
