TImage Class Reference

An abstract interface to image processing library.

It allows for the reading and writing of images in different formats, several image manipulations (scaling, tiling, merging, etc.) and displaying in pads.

The concrete implementation of this class is done by the TASImage class. The methods are documented in that class.

Clone()

TObject * TImage::Clone ( const char *  newname ) const

inlineoverridevirtual

Make a clone of an object using the Streamer facility.

If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.

If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.
