2022-11-29Fix for issue [Cairo]: Arrows have a "gap" (#561)ManoloFLTK
The problem to fix is that the arrow drawn by draw_arrow1() in src/fl_symbols.cxx displays a faint clear line between the stem and head of the arrow with the Cairo graphics driver. This occurs because draw_arrow1() draws the arrow in 2 steps (a rectangle + a triangle) and the Cairo driver is configured to use antialiasing when filling polygons. The antialiasing produces the faint line between stem and head. Why does draw_arrow1() draw a rectangle + a triangle rather than a 7-vertex polygon? That's because the X11 graphics driver fails with its polygon- drawing function when the polygon is also rotated: the polygon is drawn empty. We want to keep using antialiasing under Cairo for polygons because the result is better with non horizontal/vertical polygon edges. This implementation changes function draw_arrow1() which draws the arrow as a 7-vertex filled polygon except when the graphics driver returns false for its virtual member function can_fill_non_convex_polygon(). In that situation, draw_arrow1() draws, as before, a rectangle + a triangle. The new, virtual member function can_fill_non_convex_polygon() returns true except for the X11 graphics driver. Therefore, draw_arrow1() is effectively unchanged under the X11 driver.
2022-11-24Refactor code to make rounded rectangles accessible (#553)Matthias Melcher
This adds fl_rounded_rect and fl_rounded_rectf so the user can draw rounded rectangles. This uses existing and optimised code that is rearranged.

2020-11-12Fix for issue #155 - continuedManoloFLTK
The issue lies in details how floating point scaled coordinates are converted to integer values and its impact on the drawing of large SVG images. This commit fixes the X11 platform. The macOS platform is immune because drawing uses floating point coordinates. The Windows platform still needs fixing.

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.
