Overview of LEADTOOLS File Metadata SDK Technology

"Metadata" refers to extra information that is stored with a file that may not be necessary for decoding the data. Metadata may contain 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. Metadata includes markers, tags and comments.

  • Read, write and modify standard metadata types such as EXIF, GeoTIFF and IPTC
  • Read, write and modify custom metadata elements
  • Determine if a file format supports metadata
  • Read or write a specific tag or comment by ID
  • Read all tags and comments found in a file without loading the image
  • Update comments or tags in a file without loading the image
  • Automatically load all the tags and comments when the file is loaded
  • Automatically load, update and save image tags
  • Delete tags by ID from files without loading the files
  • Read and write file stamps or thumbnails
  • Native 32 and 64 bit binaries to load, save, and modify file metadata
