Methods

NameDescription
override CacheData()This method does nothing as the current implementation of the EpsImage class does not involve caching data. While it may not perform any action, understanding this behavior is crucial for developers working with EPS images, ensuring efficient resource management and optimal performance within their applications.
CanSave(ImageOptionsBase)Determines whether image can be saved to the specified file format represented by the passed save options.
