Introducing Unsplash Image Fetcher: A Practical Approach to Image Processing
Published: 2024-01-14 18:48:28

## Overview
Welcome to the first iteration of the Unsplash Image Fetcher, a Python script tailored for developers, designers, and content creators. This script efficiently sources and processes images based on your input theme, simplifying a task that often consumes valuable time.

## Version 1.0 Features
**Theme-Based Image Fetching:** Select a theme and the script fetches corresponding images from Unsplash.
**Resizing:** Automatically resizes images to 64x64 pixels.
Aspect Ratio Selection: Option to fetch images with equal aspect ratios.
**Grayscale and Contrast Enhancement:** Converts images into high-contrast grayscale versions.
**Organized Saving:** Saves original and transformed images in separate directories for easy access.

## Code Snippet: Fetching and Resizing Images
```
def fetch_images_from_unsplash(theme, config):
    """
    Fetches images from Unsplash based on the provided theme and configuration.
    If 'match_aspect_ratio' in the configuration is True, only fetches images that have an equal aspect ratio.
    Resizes the fetched images to 64x64 pixels and returns them as a list of PIL Image objects.
    """
    print(f"Fetching images for theme: {theme}")
    response = requests.get(f'https://api.unsplash.com/search/photos?query={theme}&client_id={UNSPLASH_ACCESS_KEY}')

    if response.status_code == 200:
        data = response.json()
        images = []
        for i, result in enumerate(data['results']):
            img_url = result['urls']['small']
            img_response = requests.get(img_url)
            img = Image.open(BytesIO(img_response.content))
            
            # Check if the image has an equal aspect ratio
            if not config['match_aspect_ratio'] or img.width == img.height:
                # Resize the image to 64x64 pixels
                img = img.resize((64, 64))
                images.append(img)
                print(f"Image {i+1} fetched and resized")
            else:
                print(f"Image {i+1} skipped due to unequal aspect ratio")
        
        print(f"Finished fetching images for theme: {theme}")
        print(f"Number of images retrieved: {len(images)}")
        if len(images) == 0:
            print(colored('No images were retrieved.', 'red'))
        print('-'*50)
        return images
    else:
        print(f"Failed to get images for theme '{theme}' from Unsplash API. Status code: {response.status_code}")
        return []
```

## Current Limitations and Upcoming Version 2.0

While effective, version 1.0 has its limits. It's a standalone script without a user interface, making it more suitable for those comfortable with command-line tools. Recognizing this, version 2.0 aims to include:

**React App Integration:** Launching a user-friendly front-end.
**Enhanced Customization:** More configuration options for image processing.
**User Feedback Integration:** Implementing features based on user suggestions.

# Ideation for Version 2.0 Features
**Batch Processing:** Allow multiple themes in one go for bulk image handling.
**Image Filtering Options:** Introduce filters like brightness, contrast, and saturation adjustments.
**Download Quality Selection:** Choose the resolution for downloaded images.
**Interactive UI:** A simple and intuitive interface for non-programmers.
**Social Media Integration:** Directly upload edited images to social platforms.

## Code Example: Grayscale Conversion
```
def convert_to_grayscale_and_contrast(image):
    """
    Converts the provided image to grayscale and applies high contrast.
    Returns the converted image.
    """
    grayscale_image = ImageOps.grayscale(image)
    high_contrast_image = ImageOps.autocontrast(grayscale_image)
    return high_contrast_image
```

## Repository and Collaboration
The script is available on GitHub, inviting collaboration and improvements. You're encouraged to contribute ideas, report bugs, or suggest enhancements. Check out the [repo](https://github.com/MAKaminski/IconGenerator) here.

## Conclusion
Version 1.0 of the Unsplash Image Fetcher marks the beginning of a journey towards more streamlined image processing. It's a functional tool, but with your feedback and contributions, version 2.
