Description of OvImportCmd

class OvImportCmd : public Command (Return to index)

command for importing arbitrary graphical files.

Type:

Instantiable
Base Classes:

Include file:

OverlayUnidraw/ovimport.h

Description:

command for importing arbitrary graphical files: a wide variety of raster files, idraw "PostScript" and regular "PostScript", compressed or not compressed, by URL or pathname. Useful static methods for constructing components, as well as full-on command for hooking into a file menu.
