Swayimg
Image viewer for Sway/Wayland
The program uses Sway IPC to determine the geometry of the currently focused container. This data is used to calculate the position and size of the new "overlay" window that will be used to draw the image. In the next step, swayimg adds two Sway rules for the self window: "floating enable" and "move position". Then it creates a new Wayland window and draws the image from the specified file.
