ImageMime final class

Minn\Media\ImageMime · public/minn/src/Minn/Media/ImageMime.php · 34 lines

An image file's real type from its first bytes, as the reference sniffs it before trusting an upload's extension (probe hook-inputs-2): PHP's own header check for the classic formats (JPEG, PNG, GIF, WebP, BMP, ICO, TIFF, AVIF), then an ISO media file's major brand for the HEIF family PHP does not know. A file too short or of another kind has no image type.
