WP Image Color Palette

Description

Features:

• Extracts colors from attachment images and saves it to the post meta.
• Several php functions to receive the post meta or extract data from images on the fly.

PHP functions

You can find your image swatches in the post meta. There are two global php functions to get these values:

wpip_get_post_thumbnail_color( int|WP_Post $post )

Gets the main rgb color from a post.

wpip_get_post_thumbnail_colors( int|WP_Post $post )

Gets the main rgb colors from a post.

Advanced users may also like the following functions to extract the colors from any image they want in WordPress.

wpip_get_image_color( string $file, int $precision = 20, int $palette_length = 5 )

Gets the main color from an image.

wpip_get_image_colors( string $file, int $precision = 20, int $palette_length = 5 )

Gets the image color palette.

How can I get the colors from my post?

Short: wpip_get_post_thumbnail_colors

You can find a list of all functions in the PHP functions section.

Why are there no colors in my post?

Short: Update your post (again).

The color palette for a post is generated the moment you save a post or page. So you have to save a post at least once, after the Plugin was activated.

A functionality for a bulk update is already on the roadmap.

Why is post type XY not in the post-type list?

Only post types with ‘custom-fields’ support can be selected. Check your post type with the post_type_support function.
