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

2016-01-271) Added a new way to detect whether the drawing operation is using the ↵Manolo Gouy
platform's native driver and whether we are printing: virtual int Fl_Graphics_Driver::has_feature(driver_feature feature) This is also because it is not convenient to derive a printer-specific driver with its own implementation of virtual functions when this implementation differs only in one line of code. 2) Solved the problem of inclusion of non public header by the public header FL/Fl_Device.H: bracket this with #if FL_LIBRARY / #endif so this non public header is included only when building FLTK itself. 3) Removed several (but not all) of the FLTK_ABI_VERSION guards that are no longer useful for code targeting FLTK 1.4. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11063 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2015-06-21Fix Fl_Pixmap (background) drawing to respect the clip region (STR #3206).Albrecht Schlosser
STR title: (Re-)drawing artefacts with scheme plastic after STR 3059. It turned out that drawing a pixmap could enlarge the clip region if the intersection of the clip region and the pixmap was not a single rectangle. Hence drawing the background pixmap would draw outside the clip region and leave artefacts when a widget was drawn on top of it. See STR #3206. Thanks to Manolo who had the idea and provided a patch to draw into the individual rectangles of a multi-rectangle clip region. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10771 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2012-03-28WIN32: Fl_Pixmap printing uses a global variable called win_pixmap_bg_color ↵Manolo Gouy
equal to the color used for the pixmap background, and treats this color as transparent. FLTK assigns to this variable a color unused by the processed pixmap. In theory this variable should be specific to each processed pixmap. In practice, it's very unlikely that several values are needed. A new member variable is added to the Fl_Pixmap object to hold this value. This member is made static if FLTK_ABI_VERSION < 10302 for ABI compatibility. The correct thing, though, is for a non-static member. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@9308 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
