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; PostScript 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.
