2019-06-06Add one argument to Fl_Screen_Driver::read_win_rectangle()ManoloFLTK
The new argument gives the window to be captured, or NULL to indicate capture from the current offscreen. Calling this function becomes easier because less dependent on global variables.

2019-03-11X11 platform: follow when the OS changes the Xft.dpi resourceManoloFLTK
Under gnome, Tweaks -> Fonts ->Scaling factor allows to change the size of all fonts handled by gnome. With that change, FLTK apps obey to changes to Xft.dpi.
2019-03-10X11 platform: use the Xft.dpi resource as basis for the initial GUI scaling ↵ManoloFLTK
factor Previously, the display scaling factor value under gnome was sought in the gnome database using the gnome_scale_factor() function. But that information is no longer present. File $HOME/.config/monitors.xml was also used to get that information. Using the Xft.dpi X resource is simpler and more general because it's effective both for gnome and KDE.
2019-03-06Process env var FLTK_SCALING_FACTOR consistently across platforms.ManoloFLTK
The procedure to set screen scaling factors becomes: 1) each screen scaling factor is set to 1 2) the OS is queried according to each platform to get screen scaling factor values 3) The value of FLTK_SCALING_FACTOR, if present, is used to multiply scaling factors

2019-02-19X11 + gnome: improve detection of the current display scale factorManoloFLTK
Gnome now seems to store the value of the display scale factor in file $HOME/.config/monitor.xml. Previously, that value was readable with the gsettings command. The present commit uses the information found in that file and reverts back to the gsettings command if that information is not found.

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.

2017-05-17Introduce HiDPI + rescaling support for the X11 platform (+ partial support ↵Manolo Gouy
for WIN32) Corresponds to STR #3320 1) HiDPI support consists in detecting the adequate scaling factor for the screen on which FLTK maps a window, and scaling all FLTK units by this factor. FLTK tries to detect the correct value of this factor at startup (see more details below). Environment variable FLTK_SCALING_FACTOR can also be used to set this value. 2) Rescaling support consists in changing the scaling factor of all FLTK windows in reply to ctrl/+/-/0/ keystrokes. More details for the various platforms : - X11: Support is very advanced. Some details need still to be improved. Automatic detection of the correct starting value of the scaling factor works well with the gnome desktop. The present code contains no support for this on other desktops. FLTK_SCALING_FACTOR provides a workaround. -WIN32: Support is incomplete at this point, although many test applications have partial or complete HiDPI and scaling support. The current value of the system's scaling factor is correctly detected at application startup. Apps respond to changes of this value in real time. Support needs to define the FLTK_HIDPI_SUPPORT preprocessor variable at compile time. This way, standard builds produce a code with the default WIN32 HiDPI support, that is, where all graphics goes to an internal buffer that gets enlarged by the system and then mapped to the HiDPI display. To experiment with (or develop) the new HiDPI support requires a modified build procedure in which FLTK_HIDPI_SUPPORT is defined at compile time. When the support will be complete, the requirement for the definition of this preprocessor variable will be removed. The present commit contains support for a single scaling factor. Eventually, per-screen scaling factors should be implemented, as done for X11. - MacOS: this commit does not give new HiDPI for this platform. Eventually, window rescaling in reply to command/+/-/0/ is desirable. Per-screen scaling factor makes no sense on this platform because the OS itself takes care of the difference between the resolutions of traditional and retina displays. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12239 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2016-08-23Fix compiler warnings and simplify Fl_X11_Screen_Driver::init().Albrecht Schlosser
This function sets the screen dimensions and tries to use Xrandr, Xinerama, and basic X11 functions (in this order) to get the screen sizes and resolutions (dpi). This commit simplifies conditional compilation and fixes "unused variable" compiler warnings under certain conditions as mentioned by Greg in fltk.general, thread "Can not change font size in Kubuntu 16.04" on Mon, 15 Aug 2016 00:25:32 -0700. Also merged in small improvements of branch-1.3-porting, basically "the same commit" as svn r11889 in branch-1.3. Todo: dpi resolutions acquired by using Xrandr are not per screen but use dpi value of screen 0 for all screens. Check if this can be improved. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11890 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
