Creotec Title Card Images for Open Graph creates a generated JPEG or WebP image for supported 
posts, pages, and public custom post types by combining the content title with 
the featured image. Oversized featured images are resized to a maximum width of 
1200px before the generated image is saved. The generated image is stored in:
wp-content/uploads/creotec-title-card-images-for-open-graph/
The plugin updates Open Graph image metadata for:
<ul>
<li>og:type</li>
<li>og:title</li>
<li>og:url</li>
<li>og:image</li>
<li>og:image:width</li>
<li>og:image:height</li>
<li>og:image:type</li>
</ul>
When Yoast SEO is active, the plugin uses Yoast’s Open Graph filters for the 
generated image. On supported singular content, it also checks wp_head output, 
replaces existing Open Graph image tags with the generated image tags, and adds 
only missing required non-image Open Graph tags. This allows it to work with SEO 
plugins and themes that already output Open Graph metadata.
The generated image is refreshed when the post title changes, when the featured 
image changes, when the featured image is removed, or when the plugin settings 
change.
<h3>Settings</h3>
Go to Settings > Creotec Title Card Images for Open Graph.
Available options:
<ul>
<li>Title position: above, below, or middle of the featured image.</li>
<li>Title text colour.</li>
<li>Title background colour.</li>
<li>Additional text: optional single-line text shown below the title.</li>
<li>Additional text colour.</li>
<li>Title font size, with automatic sizing available.</li>
<li>Additional text font size, with automatic sizing available.</li>
<li>Generated image format: JPEG or WebP when supported by the server.</li>
</ul>
<h3>Admin Posts List</h3>
The plugin adds an Open Graph Image column to the admin posts list. The column uses 
icons to show whether a generated image exists, is missing, is stale, or cannot 
be generated because the post has no featured image. Missing images are shown as 
a neutral status with an action icon to generate the image.
The posts list also includes a Generate Open Graph Images bulk action.
<h3>Notes</h3>
The plugin uses PHP GD to generate images. TrueType text is used when a readable 
font is available. Open Sans Bold is bundled and used by default for consistent 
rendering across environments. You can provide a specific font with the 
creotcog_font_file filter.
The bundled Open Sans font is distributed under the SIL Open Font License in 
assets/fonts/OFL.txt.
By default, public post types that support featured images are handled, 
including posts, pages, and eligible custom post types. Developers can narrow or 
adjust this with the creotcog_supported_post_types filter.

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.
For WordPress developers and open-source creators, this workspace functions as a complete asset generation kit to build graphics for the official WordPress.org plugin repository. Using the specialized “Download For Plugin” pipeline, the utility automatically scales and center-crops any source image into the four exact required deployment formats: a normal banner (<code>banner-772x250.jpg</code>), a high-DPI retina banner (<code>banner-1544x500.jpg</code>), a standard square icon (<code>icon-128x128.png</code>), and a high-DPI retina square icon (<code>icon-256x256.png</code>). These can be downloaded instantly in a single action to place directly inside your SVN assets directory.
<h3>Features</h3>
<ul>
<li>Fully isolated browser-based local engine processing via HTML Canvas APIs.</li>
<li>One-click automated asset bundle production for generating official WordPress plugin repository assets (<code>banner-772x250.jpg</code>, <code>banner-1544x500.jpg</code>, <code>icon-128x128.png</code>, and <code>icon-256x256.png</code>).</li>
<li>Automated crop boundaries featuring center, top, bottom, and smart center matrix fills.</li>
<li>Secure optional cross-origin direct asset loading.</li>
<li>Integrated dynamic save mechanics pipeline targeting the native WordPress Media Library without page reloads.</li>
<li>Comprehensive structural image manipulations including advanced sharpening algorithms and custom channel transformations.</li>
<li>No external tracking frameworks, tracking cookies, or remote script injections.</li>
</ul>
