Aspose.Imaging FOSS identifies an image file’s format and reads its basic header properties — dimensions, bit depth, and frame count — directly from the file header, without decoding a single pixel. It recognizes eleven formats — PNG, JPEG, GIF, BMP, WebP, ICO, TIFF, PSD, EMF, WMF, and DICOM — including DICOM headers across common transfer syntaxes. The library never throws on malformed or truncated input — it returns a partial result with whatever it could determine instead of raising an exception, making it safe to run against untrusted or partially downloaded files. It is intentionally scoped to format detection and header probing only; decoding, editing, and converting images requires the commercial Aspose.Imaging SDK. Aspose.Imaging FOSS is MIT licensed with zero external dependencies. For the enterprise product family, see Aspose.Imaging — Enterprise Product Family.
