The Fl_Bitmap class supports caching and drawing of mono-color (bitmap) images.
Definition Fl_Bitmap.H:42
const uchar * array
pointer to raw bitmap data
Definition Fl_Bitmap.H:49
Fl_Bitmap(const char *bits, int W, int H)
The constructors create a new bitmap from the specified bitmap data.
Definition Fl_Bitmap.H:69
int alloc_array
Non-zero if array points to bitmap data allocated internally.
Definition Fl_Bitmap.H:51
Fl_Bitmap(const uchar *bits, int W, int H)
The constructors create a new bitmap from the specified bitmap data.
Definition Fl_Bitmap.H:66
Fl_Image is the base class used for caching and drawing all kinds of images in FLTK.
Definition Fl_Image.H:51
virtual void draw(int X, int Y, int W, int H, int cx=0, int cy=0)
Draws the image with a bounding box.
Definition Fl_Image.cxx:63
const char *const * data() const
Returns a pointer to the current image data array.
Definition Fl_Image.H:118
int w() const

virtual void label(Fl_Widget *w)
The label() methods are an obsolete way to set the image attribute of a widget or menu item.
Definition Fl_Image.cxx:120
int h() const
Returns the current image height in pixels.
Definition Fl_Image.H:94
