Fl_Color
unsigned int Fl_Color
An FLTK color value; see also Colors.
Definition Enumerations.H:1120
Fl_Image.H
Fl_Image, Fl_RGB_Image classes.
Fl_Image::w
int w() const
Returns the current image drawing width in FLTK units.
Definition Fl_Image.H:131
Fl_Image::copy
Fl_Image * copy() const
Creates a copy of the image in the same size.
Definition Fl_Image.H:266
Fl_Image::h
int h() const
Returns the current image drawing height in FLTK units.
Definition Fl_Image.H:137
Fl_RGB_Image::draw
void draw(int X, int Y, int W, int H, int cx=0, int cy=0) FL_OVERRIDE
Draws the image to the current drawing surface with a bounding box.
Definition Fl_Image.cxx:728
Fl_RGB_Image::Fl_RGB_Image
Fl_RGB_Image(const uchar *bits, int W, int H, int D=3, int LD=0)
The constructor creates a new image from the specified data.
Definition Fl_Image.cxx:374
Fl_RGB_Image::desaturate
void desaturate() FL_OVERRIDE
The desaturate() method converts an image to grayscale.
Definition Fl_Image.cxx:673
Fl_RGB_Image::normalize
virtual void normalize()
Makes sure the object is fully initialized.
Definition Fl_Image.H:394
Fl_SVG_Image::proportional
bool proportional
Set this to false to allow image re-scaling that alters the image aspect ratio.
Definition Fl_SVG_Image.H:155
Fl_SVG_Image::as_svg_image
Fl_SVG_Image * as_svg_image() FL_OVERRIDE
Returns whether an image is an Fl_SVG_Image or not.
Definition Fl_SVG_Image.H:169
FL_OVERRIDE
#define FL_OVERRIDE
This macro makes it safe to use the C++11 keyword override with older compilers.
