- Public Member Functions inherited from FX::FXIcon
 FXIcon (FXApp *a, const FXColor *pix=NULL, FXColor clr=0, FXuint opts=0, FXint w=1, FXint h=1)
 Create an icon with an initial pixel buffer pix, a transparent color clr, and options as in FXImage.
virtual void create ()
 Create the server side pixmap, the shape bitmap, and the etch bitmap, then call render() to fill it with the pixel data from the client-side buffer.
virtual void detach ()
 Detach the server side pixmap, shape bitmap, and etch bitmap from the Icon.
virtual void destroy ()
 Destroy the server-side pixmap and the shape bitmap and etch bitmap.
virtual void render ()
 Render the server-side pixmap, shape bitmap and etch bitmap for the icon from the client-side pixel buffer.
virtual void resize (FXint w, FXint h)
 Resize both client-side and server-side representations (if any) to the given width and height.
FXColor getTransparentColor () const
 Get transparency color.
void setTransparentColor (FXColor color)
 Change transparency color.
FXshort getThresholdValue () const
 Get threshold value.
void setThresholdValue (FXshort value)
 Change threshold value.
virtual ~FXIcon ()
- Public Member Functions inherited from FX::FXImage
 FXImage (FXApp *a, const FXColor *pix=NULL, FXuint opts=0, FXint w=1, FXint h=1)
 Create an image.
void setOptions (FXuint opts)
 Change options.
FXuint getOptions () const
 To get to the option flags.
void setOwned (FXbool owned)
 Set pixel data ownership flag.
FXbool isOwned () const
 Get pixel data ownership flag.
virtual void setData (FXColor *pix, FXuint opts=0)
 Populate the image with new pixel data of the same size; it will assume ownership of the pixel data if image IMAGE_OWNED option is passed.
virtual void setData (FXColor *pix, FXuint opts, FXint w, FXint h)
 Populate the image with new pixel data of a new size; it will assume ownership of the pixel data if image IMAGE_OWNED option is passed.
FXColor * getData () const

virtual void restore ()
 Retrieves pixels from the server-side image.
virtual void release ()
 Release the client-side pixels buffer, free it if it was owned.
virtual void scale (FXint w, FXint h, FXint quality=0)
 Rescale pixels image to the specified width and height; this calls resize() to adjust the client and server side representations.
virtual void mirror (FXbool horizontal, FXbool vertical)
 Mirror image horizontally and/or vertically.
