Image Variants Demo

This page demonstrates the automatic image variant generation. When you upload an image, the system automatically creates multiple resized versions.

How Variants Work

1. Upload an image through the Images demo
2. The ImageProcessor automatically creates variants based on the configuration
3. Each variant is stored as a separate file with a hashed name
4. Variant metadata (paths, URLs) is stored in the database's variants JSON column
5. Access variants using $entity->getVariantUrl('variant_name')

Regenerating Variants

You can regenerate variants for existing images using the command:

# Regenerate all configured variants
bin/cake file_storage generate_image_variant --verbose

# Regenerate for specific collection
bin/cake file_storage generate_image_variant FileStorage images --verbose

# Regenerate a specific variant only
bin/cake file_storage generate_image_variant FileStorage images thumbnail --verbose

This is useful when:

• You've added new variant configurations
• You've changed existing variant operations (resize dimensions, etc.)
• You need to regenerate corrupted or missing variants
