2022-12-28Improve and extend fl_contrast() (#370)Albrecht Schlosser
- Add internal fl_contrast_cielab() as the new default. - Keep old function as internal fl_contrast_legacy(). - Add fl_contrast_mode() to switch between fl_contrast() functions. - Add fl_contrast_level() to fine tune fl_contrast() per mode. - Add option to register and use a custom contrast function. - Add test/contrast.cxx test program. - Move all fl_contrast() related code to a new file src/fl_contrast.cxx. - Add fl_lightness() convenience function for perceived lightness. - Add fl_luminance() convenience function for physical luminance.

2022-02-06OpenGL implementation of all `fl_` "Drawing Fast Shapes" graphics calls (#385)Matthias Melcher
* Fix build system for unites, * Updated unittest to check OpenGL drawing. Making sure that OpenGL drawing is exactly the same as native drawing to make FLTK widget rendering look the same in GL windows. * Make OpenGL optional. * Implemented clipping in OpenGL * unites drawing fast shapes * Fixed CMake * Updating unittest. Added tests for fl_pi and fl_arc (int) Renamed tab to render complex shapes. * Improved OpenGL FLTK drawing emulation. * Fixed GTK ROUND DOWN BOX * Fixing Makefile for unittest * Correctly aligning OpenGL text. * Fixed text alignment in GL windows. Explained the "FLTK over GL " example in Cube. * Overlapping test. * Better GL graphics alignment. * Drawing the focus rect. * Adding Alpha Channel support for GL. * Added FLTK-on-GL documentation.
2020-07-06Remove $Id$ tags, update URL's, and moreAlbrecht Schlosser
- remove obsolete svn '$Id$' tags from all source files - update .fl files and generated files accordingly - replace 'http://www.fltk.org' URL's with 'https://...' - replace bug report URL 'str.php' with 'bugs.php' - remove trailing whitespace - fix other whitespace errors flagged by Git - add and/or fix missing or wrong standard headers - convert tabs to spaces in all source files The only relevant code changes are in the fluid/ folder where some .fl files and other source files were used to generate the '$Id' headers and footers.

2016-01-31Finish removing of #include of driver files, remove FL_LIBRARY_CMAKE.Albrecht Schlosser
Now all graphics drivers are compiled as individual files depending on the platform and configuration. The preprocessor macro FL_LIBRARY_CMAKE is now obsolete and has been removed. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11093 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2016-01-31Update build system to compile all drivers as indiviual objects.Albrecht Schlosser
Removed obsolete files that served only one purpose: to #include different driver files. Updated CMake and Makefiles to reflect the changes.

2009-01-21Fixed fl_color() setters would crash under X11 when called with no valid fl_gc.Fabien Costantini
The fix prefer not to set a default gc to avoid side unpredictable side effects (i.e: the color would not be set on the expected window) Maybe this could be later further improved by using fl_GetGC() with the current or the first fltk window so that a color would always be set. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6643 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
