Add classes Fl_SVG_File_Surface and Fl_EPS_File_Surface to draw to SVG and EPS.
Test programs device and pixmap_browser use these new classes. Class Fl_SVG_File_Surface can be optionally made non functional using the --disable-svg configure option or turning off OPTION_USE_SVG in CMake. Class Fl_EPS_File_Surface can be optionally made non functional using the --disable-print configure option or turning off OPTION_PRINT_SUPPORT in CMake.

New Features and Extensions
|
||||
|
||||
- (add new items here)
|
||||
- New classes Fl_SVG_File_Surface and Fl_EPS_File_Surface to save any FLTK
|
||||
graphics to SVG or EPS files, respectively.
|
||||
- New fl_putenv() is a cross-platform putenv() wrapper (see docs).
|
||||
- New Fl::keyboard_screen_scaling(0) call stops recognition of ctrl/+/-/0/
|
||||
keystrokes as scaling all windows of a screen.

|

of Fl_Clock, Fl_Clock_Output, and derived widgets.
|
||||
- New method Fl_Tabs::tab_align() allows to set alignment of tab labels,
|
||||
particularly to support icons on tab labels (STR #3076).
|
||||
- Added '--enable-print' option to configure effective under X11 platforms
|
||||
and with 'yes' default value. Using '--enable-print=no' removes print
|
||||
and PostScript support from the FLTK library, thus reducing its size.
|
||||
- Added Fl_Surface_Device::push_current(new_surface) and
|
||||
Fl_Surface_Device::pop_current() to set/unset the current surface
|
||||
receiving graphics commands.

New Configuration Options (ABI Version)
|
||||
|
||||
- The library can be built without support for SVG images using the
|
||||
--disable-nanosvg configure option or turning off OPTION_USE_NANOSVG in CMake.
|
||||
- The library can be built without support for reading SVG images or writing
|
||||
graphics in SVG format using the --disable-svg configure option
|
||||
or turning off OPTION_USE_SVG in CMake.
|
||||
- The library can be built without support for PostScript, thus reducing
|
||||
its size, using the --disable-print configure option or turning off
|
||||
OPTION_PRINT_SUPPORT in CMake. That makes classes Fl_PostScript_File_Device,
|
||||
Fl_EPS_File_Surface and Fl_Printer (under X11 platform only) ineffective.
|
||||
- FLTK's ABI version can be configured with 'configure' and CMake.
|
||||
See documentation in README.abi-version.txt.

Other Improvements

- (add new items here)

- Support for building for the arm64 architecture used by macOS 11.0 "Big Sur".

a string describing the error when an error occurs.
