## Installation

To install OptimaImg, simply run the following command:

```bash
pip install optimaimg
```

Alternatively, if you have cloned the repository and want to install it directly from the source code, you can run:

```bash
poetry install
```

## Important Note

**OptimaImg has not been tested on Windows OS and may not perform as expected on that platform.**

## Usage

After installing the package, you can use it to perform various image processing tasks:

### Convert an Image to Grayscale

To convert an image to grayscale, you can use the `convert_to_grayscale` function:

```python
from optimaimg import convert_to_grayscale

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/grayscale_image.png'

# Convert the image to grayscale and save it
convert_to_grayscale(input_path, output_path)
```

### Resize an Image

To resize an image to specific dimensions, use the `resize_image` function:

```python
from optimaimg import resize_image

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/resized_image.png'
width = 100  # desired width
height = 100 # desired height

# Resize the image and save it
resize_image(input_path, output_path, width, height)
```

### Rotate an Image

To rotate an image by a specific rotation angle in degrees, use the `rotate_image` function:

```python
from optimaimg import rotate_image

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/rotated_image.png'
degree = 45 # desired degree

# Rotate the image and save it
rotate_image(input_path, output_path, degree)
```

### Apply Blur

To apply a Gaussian blur to an image:

```python
from optimaimg import apply_blur

# Apply a blur with a sigma value of 2.0
apply_blur(input_path, output_path, sigma=2.0)
```

### Apply Sharpen

To sharpen an image:

```python
from optimaimg import apply_sharpen

# Sharpen the image
apply_sharpen(input_path, output_path)
```

### Apply Edge Detection

To apply edge detection to an image:

```python
from optimaimg import apply_edge_detection

# Detect edges in the image
apply_edge_detection(input_path, output_path)
```

### Apply Sepia Filter

To apply a sepia tone filter to an image:

```python
from optimaimg import apply_sepia

# Apply a sepia tone filter
apply_sepia(input_path, output_path)
```

### Adjust Saturation

To adjust the saturation of an image, thereby enhancing or muting its colors, use the `adjust_saturation` function:

```python
from optimaimg import adjust_saturation

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/saturation_adjusted_image.png'
factor = 1.5  # factor > 1 increases saturation, factor < 1 decreases saturation

# Adjust the saturation of the image and save it
adjust_saturation(input_path, output_path, factor)
```

### Adjust Brightness

To adjust the brightness of an image:

```python
from optimaimg import adjust_brightness

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/brightness_adjusted_image.png'
brightness = 1.2  # value > 1 increases brightness, value < 1 decreases brightness

# Adjust the brightness of the image and save it
adjust_brightness(input_path, output_path, brightness)
```

### Adjust Contrast

To adjust the contrast of an image:

```python
from optimaimg import adjust_contrast

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/contrast_adjusted_image.png'
contrast = 1.2  # value > 1 increases contrast, value < 1 decreases contrast

# Adjust the contrast of the image and save it
adjust_contrast(input_path, output_path, contrast)
```

### Adjust Hue

To adjust the contrast of an image:

```python
from optimaimg import adjust_contrast

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/contrast_adjusted_image.png'
hue = 1.2  # value > 1 increases contrast, value < 1 decreases contrast

# Adjust the hue of the image and save it
adjust_hue(input_path, output_path, hue)
```

### Batch Resize Images

Batch resize images to the specified dimensions:

```python
from optimaimg import batch_resize_images

input_images_path = ["path/to/image1", "path/to/image2"]
output_path = 'path/to/save/images/'
width = 20
height = 20

batch_resize_images(input_images_path, output_path, width, height)
```

### Convert Image Color Space

Convert images between different color spaces such as HSV or RGB.

```python
from optimaimg import convert_color_space

input_path = 'path/to/your/image.jpg'
output_path = 'path/to/save/converted_image.jpg'

# Convert the image color space from RGB to HSV
convert_color_space(input_path, output_path, 'rgb', 'hsv')
```

### Overlay images

Overlay an image onto another

```python
from optimaimg import overlay_images

input_path = 'path/to/your/image.jpg'
overlay_path = 'path/to/your/overlay-image.jpg
output_path = 'path/to/save/converted_image.jpg'
x = 100  # The x-coordinate of the overlay position on the base image.
y = 100 # The y-coordinate of the overlay position on the base image.
alpha = 0.2 # The transparency of the overlay (0.0 to 1.0).

overlay_images(inputh_path, overlay_path, output_path, x, y, alpha)
```

### CLI Usage Examples
