# Transparent PNG
[](https://hub.docker.com/r/hjerpbakk/transparent-png)
`transparent_png` is a simple Python script for creating a transparent PNG of a given size.
## Usage
```bash
python transparent_png.py [OPTION] [X] [Y]
```
### Options
| Option | Description |
|--------|------------------------------------------------------------------------|
| -o | Optimizes the created image using ImageOptim, if available, or PNGOUT. |
### Examples
```bash
python transparent_png.py 42 1337
```
Creates an image with a width of 42 and a height of 1337, with the name `42x1337.png` and saves it to the current directory.
```bash
python transparent_png.py -o 100 50
```
Creates an image of size 100x50 with the name `100x50.png`, optimizes it using [ImageOptim](https://imageoptim.com/mac) (if available on macOS) or [PNGOUT](http://www.jonof.id.au/kenutils) (*nix or Windows) and saves the image to the current directory.
## Running through Docker
Instead of having Python installed on your machine, make Docker do the heavy lifting for you.
### Example running with the image from Docker Hub
A Docker image is [available on Docker Hub](https://hub.docker.com/r/hjerpbakk/transparent-png).
```bash
docker run -v $(pwd):/app/image hjerpbakk/transparent-png 42 1337
```
The above command creates an image of size 42x1337 with the name `42x1337.png` and saves it to the current directory.
Using Docker, the same options are available as before. Thus, the following command creates an image of size 100x50 with the name `100x50.png`, optimizes it using PNGOUT and saves the image to the current directory.
```bash
docker run -v $(pwd):/app/image hjerpbakk/transparent-png -o 100 50
```
### Building the image locally
If you want to build the image yourself, use the following command:
```bash
docker build -t hjerpbakk/transparent-png .
```
