Member Function Documentation
◆ close()
|
overridevirtual |
Closes the file.
Implements ml::MLImageFormatAbstractFileHandle.
◆ getFileSize()
|
overridevirtual |
Returns the current complete file size. If an error occurs, a value <0 is returned.
Implements ml::MLImageFormatAbstractFileHandle.
◆ read()
