kj-boomer
=====

a zoomer application for linux...

takes a screenshot and lets you pan, zoom, and
shine a flashlight around it.

a zig port of the original boomer by tsoding with no frills.

this is a personal re-implementation, so don't expect much. it works on my machine.


features
--------

- fullscreen screenshot viewer with smooth zoom and pan
- flashlight effect that follows your cursor
- soft edge option for the flashlight
- configurable texture filtering
- mirror mode


default controls
----------------

esc or q      quit
0             reset camera and flashlight
f             toggle flashlight
m             mirror image horizontally
r             reload configuration
=             zoom in
-             zoom out
left mouse    pan the image
scroll wheel  zoom in/out
ctrl+scroll   change flashlight radius

you can change the controls in src/config.zig and recompile.
