LEADTOOLS File Metadata SDK

File Metadata

With LEADTOOLS, .NET (C# & VB), C/C++, WinRT, iOS, OS X, Java and Web developers can load, save and modify metadata for several different image and document formats.

"Metadata" refers to extra information that is stored with a file that may not be necessary for decoding the data. Metadata may come 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 the image was created, and where the image was captured.

Overview of LEADTOOLS File Metadata SDK Technology

  • Read, write and modify standard metadata types such as EXIF, 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 file 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 Types that Support Metadata

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