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.
