# (SCR)een (to) (P)ortable (P)ix(M)ap - (SCR2PPM)

The tiniest X11 screen capture aka. screenshot utility

# Install from flathub 

```
$ flatpak install io.github.igorlogius.scr2ppm
```

# Run via flatpak from CLI 

```
$ flatpak run io.github.igorlogius.scr2ppm [ARGS]
```

# ARGumentS 

one of `-s`,`-a` or `-w` is required and `-d` can be optionally added to add a delay before the capture

```
  -s := capture the entire screen area
  -a := capture a custom area 
  -w := capture a window  
  -d := add a delay in seconds (optional) 
```

# Output 

The output will be send to STDOUT (STanDard OUTput) and can be written to a Portable PixMap (PPM) file 
or directly piped into another programm like (image/gaphickmagics `convert`) to process it further

# Examples 

```
  scr2ppm -s > shot.ppm		      // screenshot entire screen immediately 
  scr2ppm -s | convert - shot.png // make screenshot and save it via convert as a png
  scr2ppm -s -d 10 		          // screenshot entire screen after 10 seconds
  scr2ppm -a			          // screenshot selected area immediately
  scr2ppm -w -d 5		          // screenshot window (select with mouse) after 5 seconds
  scr2ppm -a -d 3		          // screenshot custom area after 3 seconds    
```
