[viktorix]

Description

Changeset 43750 passes EXIF Data to the wp_read_image_metadata filter and changeset 43749 fixes a merge conflict by replacing sourceImageType with image_type.

Motivation and context

Fixes ClassicPress/ClassicPress-v1#38. See ticket ticket 43624 for details.

How has this been tested?

A quick way to test it is to add the following code to your functions.php. Make sure to upload a photo with exif data and replace the file path in the code. Load the website, it should show you exif data and the word "Yes!". See screenshot below.

add_action( 'wp_read_image_metadata', 'exif_data', 10, 5 );
function exif_data( $meta, $file, $image_type, $iptc = null, $exif = null ) {
		// If there is no Exif Version set return.
		if ( $exif['ExifVersion'] ) {
			$meta['test_filter'] = 'Yes!';
		}else{
			$meta['test_filter'] = 'No!';
		}
               return $meta;
}

require_once ABSPATH . '/wp-admin/includes/image.php';
$path = ABSPATH . '/wp-content/uploads/2022/06/PXL_20220611_200452520-Small.jpg';
wp_die(var_dump(wp_read_image_metadata( $path )));
