# Blinker - Scaler

The scaler module scales the frames of a stream. It receives a single input stream and passes it on with a different size.

## Configuration

The configuration of the scaler module with name `NAME` is located in the `scalers/NAME` subdirectory.

### Input Stream

The file `instream` contains the name of the stream to receive. The frames received from this stream are scaled and passed to the output stream.

### Size

The file `size` describes the size of the output stream, i.e. its dimensions. The file must contain a string `<width>x<height>`, e.g. `18x8` for 18 pixels width, 8 pixels height.

### Output Stream

The file `outstream` contains the name of the stream to send the scaled frames to.
