Описание
Eliptum Cover Image Optimizer introduces an asynchronous, sandboxed client-side processing workstation running completely within the user’s local browser environment. By manipulating pixels strictly via HTML5 canvas operations, it completely isolates production web servers from standard memory-intensive image handling overhead.
Users can safely load local resources via drag-and-drop mechanics, execute real-time relative crops, target dedicated layout viewport presets (1200×628, 1600×900, 1920×1080, 800×450), and save results locally or directly into the native WordPress Media Library.
The utility features complex lightweight filtering math including granular levels (black/white points), gamma distribution modifications, contrast adjustment matrices, pixel saturation alterations, channel-specific balances, high-pass sharpening kernels, and gray/heat/cyan/gold color mappings.

Features
- Fully isolated browser-based local engine processing via HTML Canvas APIs.
- Automated crop boundaries featuring center, top, bottom, and smart center matrix fills.
- Secure optional cross-origin direct asset loading.
- Integrated dynamic save mechanics pipeline targeting the native WordPress Media Library without page reloads.
- Comprehensive structural image manipulations including advanced sharpening algorithms and custom channel transformations.
- No external tracking frameworks, tracking cookies, or remote script injections.

Часто задаваемые вопросы
-
Does this framework introduce memory leaks or heavy server loads?
-
No. Because execution parameters map directly onto local client-side hardware via canvas processing loops, your production web host encounters absolutely zero performance impact.
-
Why do certain direct remote URLs throw security alerts?
-
Browsers strictly enforce Cross-Origin Resource Sharing (CORS) specifications. Remote servers hosting files must explicitly supply permissive headers to allow deep browser pixel operations. Using the local drag-and-drop file uploader completely bypasses this browser rule.
