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.
2022-09-11Fix regression in fl_read_image() after introduction of hybrid Wayland/X11 ↵ManoloFLTK
platform. The special use context of fl_read_image() inside the draw() function of an Fl_Double_Window, where the function should read inside the window's double buffer rather than the on-screen window, no longer worked. Removal of all uses of the fl_window global variable from platform-independent code remains necessary, because this variable is ill-defined in the Wayland/X11 library.
2022-08-29Make hybrid Wayland/X11 platform.ManoloFLTK
2021-11-16Add use of fl_capture_window() by test/deviceManoloFLTK
Also, rename fl_capture_window_part() to fl_capture_window().
2020-11-20Fix for issue #159 - continuedManoloFLTK
Changes here concentrate the fix within static function alpha_blend() and thus are visible only when drawing transparent images under X11 platform without Xrender.
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.
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.
2019-04-10Function Fl_Screen_Driver::traverse_to_gl_subwindows() is static in its classManoloFLTK
2019-04-09Add public function Fl_RGB_Image *fl_capture_window_part()ManoloFLTK
In the context of HighDPI screens, the API of function fl_read_image() is inadequate because a rectangle of size WxH drawing units of a window may contain many more than W*H pixels. Function fl_capture_window_part() returns an Fl_RGB_Image object whose drawing size matches the size of the rectangle and whose data size matches the, possibly larger, size in pixels of the corresponding area of the mapped window.

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
2016-04-06Fix Doxygen warnings.Albrecht Schlosser
There was one obvious warning in src/fl_read_image.cxx, but others have to do with incomplete code and platform specific definitions. I'm not entirely happy with these changes.

2014-11-06Fix for STR#3142 where fl_read_image() correctly reads GL data under X11, ↵Manolo Gouy
but ignores them under MSWindows and Mac OS X. Moreover, fl_read_image() behaves differently with and without OS virtualization for X11 and MSWindows.

CHANGES: - Add fl_read_image() note and move documentation STRs back to the top of the list... fluid/fluid.cxx: - Use printer choice data instead of the label text, since we have to escape / in printer names. - Change page number in header to n/N. fluid/print_panel.*: - Don't disable properties button, ever. - Quote / in printer names. - Put copy of real printer name in the user data. - Use user data instead of label text for printer name. fluid/template_panel.*: - Only free the files array if num_files > 0. src/fl_read_image.cxx: - Use fl_visual->visual->*_mask instead of fl_*mask and fl_*shift when the XGetImage() data does not have them set. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@4157 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
