        # img2bmp-proxy

Creates monochrome bitmaps from graphical image files (such as JPEG, PNG, etc.) hosted on public URLs using image thresholding. This proxy can be used to prepare images for e-paper displays.

## Usage

```bash

curl http://localhost:8080/?width=1024&height=469&threshold=200&url=https://upload.wikimedia.org/wikipedia/commons/thumb/1/11/Test-Logo.svg/2560px-Test-Logo.svg.png

```

| URL Parameter | Description                                                                                                                      |

| ------------- | -------------------------------------------------------------------------------------------------------------------------------- |

| `width`       | Width to resize the image to                                                                                                     |

| `height`      | Height to resize the image to                                                                                                    |

| `threshold`   | Pixel threshold value
If the pixel value is smaller than the threshold, it's set to 0, otherwise it's set to a maximum value. |

| `url`         | Image URL                                                                                                                        |
