2022-09-11Fix fl_read_image() under hybrid Wayland/X11 platform.ManoloFLTK
Function fl_read_image() obliges to keep a minimal use of global variable fl_window also under the Wayland platform, even if its type (Window) makes little sense for the hybrid library because it has its X11 value (given by X11/X.h) which is not meaningful for the Wayland leg of the hybrid platform. Virtual member function Fl_Surface_Device::as_image_surface() becomes useless.

The deprecated methods are now calling the new methods to be entirely compatible. These methods should be removed in 1.5.0 (fix unrelated whitespace as well)

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.

high_res, Fl_Offscreen off) with non-null offscreen.

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

2017-04-24Allow the use of Fl_Image_Surface::image() also when the Fl_Image_Surface ↵Manolo Gouy
object is not the current drawing surface. This fixes an issue uncovered in a thread of fltk.general entitled fl_pop_clip: clip stack underflow! warning on X11 git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12222 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2016-12-16Improve Fl_Graphics_Driver::copy_offscreen() so it accepts an Fl_Offscreen ↵Manolo Gouy
argument even if not created by fl_create_offscreen(). With this, fl_copy_offscreen() can be used with any drawing surface (e.g., PostScript) and any Fl_Offscreen argument (e.g., returned by Fl_image_Surface::offscreen()). git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12148 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
