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

2018-03-19New 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

2018-02-09Fix 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

correctly the cached offscreen object. This bug was detected by a test program that rotates an SVG image. But it's not related to SVG, and concerns any Fl_RGB_Image on the WIN32 platform.

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

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
