With LEADTOOLS, developers can load, save and modify metadata for several different image and document formats such as JPEG, JPEG2000, PNG, TIFF, PDF, DICOM and more. .NET (C# & VB), C/C++, WinRT, iOS, OS X, Java and Web developers 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 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 of creation, and location that the image was captured.
