# Library for converting RGB / Grayscale numpy images from to base64 and back.

## Installation

```bash

pip install -U image_to_base_64

```

## Conversion

Takes `numpy.array` or `PIL.Image` as input

### RGB to base 64

```python

base64 = rgb2base64(rgb_image, image_format)

```

where image format is `JPEG`, `PNG`

### Grayscale to base 64

```python

base64 = grayscale2base64(grayscale_image)

```

### Base64 to RGB image

```python

output_type = "cv2" # or "PIL"

rgb_image = base64_to_rgb(base64, output_type)

```

### Base64 to Grayscale image

```python

output_type = "cv2" # or "PIL"

grayscale_image = base64_to_grayscale(base64, output_type)

```

#### Issues

For some reason I cannot convert `RGB` image to `JPEG` representation in base 64 and back without losses.

=> test only for `PNG` and not `JPEG`
