# depth-map-processor
Normalize 16-bit PNG depth maps to 8-bit grayscale with an optional Turbo
colormap visualization.
## Install
```bash
cargo install depth-map-processor
```
## CLI Usage
```bash
depth-map-processor --input depth_16bit.png --output depth_gray.png --viz depth_turbo.png
```
## Library Usage
```rust
use std::path::Path;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let stats = depth_map_processor::process_depth_map(
Path::new("depth_16bit.png"),
Path::new("depth_gray.png"),
Some(Path::new("depth_turbo.png")),
)?;
println!("{}x{}", stats.width, stats.height);
Ok(())
}
```
## Output
- Grayscale normalization uses min/max from the 16-bit input.
- Visualization uses the Turbo colormap.
