pub fn detect_standard_format(data: &[u8]) -> Option<StandardFormat>Expand description
Detect a standard image format from the first bytes of image data.
Note: TIFF-based RAW formats (DNG, ARW, NEF, CR2) share the TIFF magic
bytes and will be detected as StandardFormat::Tiff. Use [RawFile::open()]
to distinguish RAW formats first.
Returns None if the format is not recognised or if data is too short.
