space-only, fixed doxygen keywords prepended with @ to use a backward slash instead. No code was changed. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12970 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2018-05-12Remove public member function Fl_Window_Driver *Fl_Window::driver() so class ↵Manolo Gouy
Fl_Window_Driver is not in FLTK public API. This function is replaced by static Fl_Window_Driver* Fl_Window_Driver::(const Fl_Window *win). The purpose is to have class Fl_Window_Driver outside from FLTK ABI. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12915 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2018-04-26Simplify API for Fl_Image_Surface::Fl_Image_Surface(int w, int h, int ↵Manolo Gouy
high_res, Fl_Offscreen off) with non-null offscreen. The caller no longer needs to call Fl_Image_Surface::get_offscreen_before_delete() before object deletion, because the object destructor knows the offscreen has not been created by the Fl_Image_Surface constructor. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12874 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2018-04-12Image drawing: simplify the code organisation to better support ↵Manolo Gouy
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

2018-04-05X11: Fix drawing of sliders with gtk+ scheme and GUI scaling >= 2 that left ↵Manolo Gouy
footprints when moved. The fix is to use the X11 graphics driver's line_delta_ private member variable also when drawing complex shapes with fl_begin_loop(). The gtk+ scheme does use fl_begin_loop() to draw its frames. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12821 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2018-03-22Rename Fl_Image::pixel_w() and pixel_h() to Fl_Image::data_w() and data_h().Manolo Gouy
The docs of class Fl_Image and of Fl_Image::scale() are beefed up. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12784 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

2018-03-13Improve and simplify X line and rect 16-bit clipping.Albrecht Schlosser
Back to 16-bit coordinate limit clipping (actually +/- (2**15 - 8). The clipping range is now constant, symmetrical, and stored in the driver object. Also fixed a bug in Liang-Barsky line clipping algorithm. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12744 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2018-03-10Fl_Xlib_Graphics_Driver::scale_clip: restrict the computed X11 region to the ↵Manolo Gouy
16-bit coordinate space. This member function transforms the current clip region from FLTK units to pixel units multiplying FLTK units by the current value of the scale factor to get pixel units. The current clip region has been, by construction, restricted to the 16-bit coordinate space. But these data can evade this space after multiplication by the scale factor. Thus, it's necessary to enforce the 16-bit space here which is done with Fl_Xlib_Graphics_Driver::XRectangleRegion. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12727 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

2018-02-09Replace "WIN32" with "_WIN32" or "Windows".Albrecht Schlosser
Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32". Replace "WIN32" in text and documentation with "Windows". Replace "MSWindows" with "Windows". To do: README.Windows.txt (and maybe other documentation as well) needs updates. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12655 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2018-02-09Fix fl_read_image() under MacOS platform when GUI is rescaled.Manolo Gouy
This commit also simplifies the platform-dependent support of fl_read_image(): only Fl_XXX_Screen_Driver::read_win_rectangle() contains platform-specific code to capture pixels from the current window or from an offscreen buffer. Platform-independent function Fl_Screen_Driver::traverse_to_gl_subwindows() captures subwindows that intersect with the area fl_read_image() targets. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12653 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2017-12-18STR#3444: Add MacOS support for application rescaling (not quite complete)Manolo Gouy
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). SVG images are re-rasterized after app scaling for optimal drawing. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12594 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
