File Metadata SDK Technology

With LEADTOOLS, developers can load, save, and modify metadata for several different image and document formats such as JPEG, JPEG 2000, PNG, TIFF, PDF, DICOM, and more. Developers creating .NET (C# & VB), C/C++, iOS, macOS, Linux, Java, and web applications can use LEADTOOLS to work with both standardized metadata types as well as custom metadata elements without wasting processor power on decompressing and recompressing image data.

"Metadata" refers to extra information that is stored within a file that may not be necessary for decoding the data. Metadata comes in the form of markers, tags, and comments, and typically contains information such as the manufacturer and model of the device used to capture the image, author, date and time of creation, and location that the image was captured.

Overview of LEADTOOLS File Metadata SDK Technology

  • Read, write, and modify standard metadata types such as EXIF, XMP, GeoTIFF, and IPTC
  • Read, write, and modify custom metadata elements
  • Read and write file stamps or thumbnails
  • Read or write a specific tag or comment by ID
  • Read all tags and comments found in a file without loading the image
  • Write, delete, and update comments or tags in a file without loading the image
  • Automatically load and save all the tags and comments when the file is loaded or saved
  • Determine if a format supports metadata
  • Native 32 and 64-bit binaries to load, save, and modify file metadata
  • Add file metadata support to single or multithreaded applications

Examples of File Formats that Support Metadata

Many file formats support metadata. Below is a non-exhaustive list of some of today's most popular formats that store metadata.
