Public Member Functions

 Fl_XPM_Image (const char *filename)
 The constructor loads the XPM image from the name filename.
 
- Public Member Functions inherited from Fl_Pixmap
virtual void color_average (Fl_Color c, float i)
 The color_average() method averages the colors in the image with the FLTK color value c.
 
Fl_Imagecopy ()
 
virtual Fl_Imagecopy (int W, int H)
 The copy() method creates a copy of the specified image.
 
virtual void desaturate ()

virtual void draw (int X, int Y, int W, int H, int cx=0, int cy=0)
 Draws the image with a bounding box.
 
 Fl_Pixmap (char *const *D)
 The constructors create a new pixmap from the specified XPM data.
 
 Fl_Pixmap (const char *const *D)
 The constructors create a new pixmap from the specified XPM data.
 
 Fl_Pixmap (const uchar *const *D)
 The constructors create a new pixmap from the specified XPM data.
 
 Fl_Pixmap (uchar *const *D)
 The constructors create a new pixmap from the specified XPM data.
 
virtual void label (Fl_Menu_Item *m)
 The label() methods are an obsolete way to set the image attribute of a widget or menu item.
 
virtual void label (Fl_Widget *w)
 The label() methods are an obsolete way to set the image attribute of a widget or menu item.
 
virtual void uncache ()
 If the image has been cached for display, delete the cache data.
 
virtual ~Fl_Pixmap ()
 The destructor frees all memory and server resources that are used by the pixmap.
 
- Public Member Functions inherited from Fl_Image
Fl_Imagecopy ()
 The copy() method creates a copy of the specified image.
 
int count () const
 The count() method returns the number of data values associated with the image.

int fail ()
 Returns a value that is not 0 if there is currently no image available.
 
 Fl_Image (int W, int H, int D)
 The constructor creates an empty image with the specified width, height, and depth.
 
int h () const
 Returns the current image height in pixels.
 
void inactive ()
 The inactive() method calls color_average(FL_BACKGROUND_COLOR, 0.33f) to produce an image that appears grayed out.
