# CBoomer
A C port of [Boomer](https://github.com/tsoding/boomer) by Tsoding - a zoomer application for Linux. This port focuses on the core functionality (screenshot viewing, zoom, pan, flashlight) and does not yet implement live window tracking (honestly, I've never used it)
## Features
- Fullscreen screenshot viewer with smooth zoom and pan
- Flashlight effect that follows your cursor
- Clean, modular C code with single-header libraries
## Differences from original Boomer
- No live window tracking - focused on screenshot viewing only
- Additional configuration - more camera and flashlight parameters exposed in `config.h`
- Soft flashlight edges - smooth gradient instead of hard circular cutoff (you can enable it in the `config.h`)
- Configurable texture filtering - switch between pixelated and smooth (check `config.h`)
## Pre-built Binaries
Check the [Releases](https://github.com/laserattack/cboomer/releases/) page for portable Linux executables. Requires:
- Linux x86_64 system
- X11
- GPU with OpenGL support (any modern GPU works)
## Build from source
### Dependencies
- X11 development libraries (libX11, libXext, libXrandr)
- OpenGL development libraries (libGL, libGLX)
- GLEW (OpenGL Extension Wrangler)
### Build and run
```
make
./cboomer
```
For faster screenshot capture with MIT-SHM:
```
make USE_XSHM=1
./cboomer
```
## Default Controls
| Control | Action |
|---------------------------------|--------------------------|
| Esc | Quit |
| 1 | Reset camera |
| 2 | Toggle flashlight |
| = | Zoom in |
| - | Zoom out |
| Drag with left mouse | Pan the image |
| Scroll wheel | Zoom in/out |
| Ctrl + Scroll wheel | Change flashlight radius |
You can modify the controls in `src/config.h` and recompile
