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.

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.
2019-05-30X11+Pango: call pango_font_description_from_string() less oftenManoloFLTK
Previously, each time fl_font(fnum, fsize) was called, functions pango_font_description_free() and pango_font_description_from_string() would be called. Now, pango_font_description_from_string() is called only once, the first time an Fl_Font is used.

Fl_Image::scale(). Graphics drivers now use up to 6 virtual member functions to support Fl_Image drawing in the context of GUI and image rescaling : virtual void draw_pixmap(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy) virtual void draw_bitmap(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy) virtual void draw_rgb(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy) and virtual void draw_fixed(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy) virtual void draw_fixed(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy) virtual void draw_fixed(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy) git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12828 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2018-03-19New member function Fl_Image::scale(int width, int height) to set the FLTK ↵Manolo Gouy
size of an image. Each image has now two sizes implemented as follows: - the pixel size is stored in private members pixel_w_ and pixel_h_ with public accessors pixel_w() and pixel_h() - the FLTK size is stored in private members w_ and h_ and read by w() and h() - when the image is constructed, the two sizes have the same value - the protected w(int) and h(int) member functions set both FLTK and pixel sizes. - the public scale(int, int) member function is essentially nothing but set the FLTK size and don't change the pixel size. - when the image is drawn, its FLTK size determines how big it is drawn, its pixel size determines how much data are available to draw it. FLTK 1.3.4 with FL_ABI_VERSION=10304 contained an equivalent member function but only for the Fl_Shared_Image class. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12776 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2018-03-09Improve X11 (16-bit) clipping of lines and rectangles.Albrecht Schlosser
In FLTK 1.3.x only horizontal and vertical long lines with endpoints outside the 16-bit coordinate space could be drawn with proper X11 coordinate clipping. Now arbitrary lines are clipped so they can be drawn with X11 functions. All rectangles are clipped as well (as in 1.3). Todo: The code needs better documentation and clipping of polygons, circles, curves etc. is still missing. The next step should be the clipping of polygons... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12725 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

With this, most MacOS FLTK app can be scaled with command/+/-/0/ keystrokes. A scaling problem remains, visible in test/cube, where the "Test" string is not positioned correctly. GLUT apps can also be scaled (across platforms).
