Dear all,
if you upload PDF, in metadata sizes we have array with jpgs.
I tried fix with
add_filter( 'webp_uploads_upload_image_mime_transforms', 'core_webp_uploads_upload_image_mime_transforms', 9, 2 );
function core_webp_uploads_upload_image_mime_transforms( $default_transforms ) {
$mimes = wp_get_mime_types();
$output_format = webp_uploads_mime_type_supported( 'image/avif' ) ? webp_uploads_get_image_output_format() : 'webp';
$transforms = webp_uploads_is_fallback_enabled() ? array( 'image/jpeg', 'image/' . $output_format ) : array( 'image/' . $output_format );
foreach( $mimes as $k => $v ) {
if ( ! isset( $default_transforms[ $v ] ) )
$default_transforms[ $v ] = $transforms;
}
return $default_transforms;
}
If you upload PSD with mime image/vnd.adobe.photoshop and genereate sizes with some custom code (imagemagick support PSD) like PDF does
add_filter( 'wp_generate_attachment_metadata', 'core_wp_generate_attachment_metadata', 9, 2 );
it working ok. I have nice jpg and avif in metadata.
But, different situation is with PDF mime application/pdf. It is blocked by helper.php line 145
$image_path = wp_get_original_image_path( $attachment_id );
and inside function is condition
if ( ! wp_attachment_is_image( $attachment_id ) ) {
We dont have any filter skip this check, so PDF avif is not working. Best would be add filter to "wp_attachment_is" and override.
Im working on LibreOffice (exec soffice), audiowave (exec https://github.com/bbc/audiowaveform ) , PSD / AI (imagemagick) thumbnailer.
