apply_filters( 'jpeg_quality', int $quality , string $context )
Filters the JPEG compression quality for backward-compatibility.
Description
Applies only during initial editor instantiation, or when set_quality() is run manually without the $quality argument.
set_quality() has priority over the filter.
The filter is evaluated under two contexts: ‘image_resize’, and ‘edit_image’, (when a JPEG image is saved to file).
Parameters
- $quality
-
(int) Quality level between 0 (low) and 100 (high) of the JPEG.
- $context
-
(string) Context of the filter.
