Detailed Description

Structure to hold some DSS image metadata.

Note
Some fields in the structure are redundant. The methods that fill this structure must be designed to fill in the redundancies correctly!

Member Enumeration Documentation

◆ FileFormat

Contains possible file formats for images.

Note
Although DSS website provides us GIF, we may convert to PNG to incorporate metadata, since by default Qt has no write support for GIF. Besides, PNG compresses better.
