NAME

       ImportCmd - import a graphical component

SYNOPSIS

       #include <Unidraw/Commands/import.h>

DESCRIPTION

       ImportCmd  imports a graphical image from a file into the drawing being edited.	ImportCmd supports the following file formats: TIFF; Post-
       Script generated by pgmtops and ppmtops; X bitmap format; and Unidraw format.

PUBLIC OPERATIONS

       ImportCmd(ControlInfo*, FileChooser* = nil)
       ImportCmd(Editor* = nil, FileChooser* = nil)
	      Create a new ImportCmd instance, optionally supplying the FileChooser that will prompt the user  to  specify  the  file  to  import.
	      After  the user specifies the file, ImportCmd reads it, creates an appropriate graphical component, and pastes it into the component
	      being edited in the enclosing editor.

       static GraphicComp* Import(const char*)
       static GraphicComp* TIFF_Image(const char*)
       static GraphicComp* PGM_Image(const char*)
       static GraphicComp* PPM_Image(const char*)
       static GraphicComp* XBitmap_Image(const char*)
	      Operations for reading data from various file formats and creating  an  appropriate  graphical  component.   TIFF_Image,	PGM_Image,
	      PPM_Image,  and  XBitmap_Image assume that the specified file is in the corresponding format.  Import is more general: it determines
	      the format from the file and then calls one of the other functions.

PROTECTED OPERATIONS

       void Init(FileChooser*)
	      Specify the FileChooser instance (stored in the _dialog protected member) explicitly.  This operation does not delete  the  existing
	      instance, if any.

       GraphicComp* PostDialog()
	      Post the FileChooser and return the graphical component created from the user-specified file, if any.
