2024-01-13Fix doxygen docs (typo, undocumented parameter)Albrecht Schlosser
2024-01-13#887: Fixes Fl_Shared_Image reference countingMatthias Melcher
- adds documentation to all calls - changes implementation details on ::copy() and copy(w,h)

2023-12-12#188: Fixes Fl_Shared_Image ref count and find opMatthias Melcher
- ported froward from 1.3.9 - fixes ref count for original and other images - fixes binary search issues
2022-06-20Fix issue #427 - 2nd partManoloFLTK
Fix Fl_Tiled_Image made from scaled source image. Fix Fl_Shared_Image::update() to allow scaled source image. Correct handling of default value (-1) of 3rd argument of 3-argument Fl_BMP_Image constructor.
2022-04-13Make Fl_Image::copy() 'const', including all derived classesAlbrecht Schlosser
Copying an image does not (and must not) change the original object, hence copy() should always be 'const'. This is *necessary* if the given Fl_Image object is 'const'.
2021-05-06Fix Windows (Visual Studio) compiler warningsAlbrecht Schlosser
2021-04-28Fix "Fl_Shared_Image: use of unitialized data" (#216)Albrecht Schlosser
- fix issue as proposed - fix more potential access to uninitialized data issues - document Fl_Shared_Image::add_handler() - document typedef Fl_Shared_Image::Fl_Shared_Handler()
2021-03-15Partial fix for issue #188.ManoloFLTK
This fixes the inconsistency created by the possibility to change img->w() and img->h() values. The fix is to use img->data_w() and img->data_h() that have constant values.
2021-02-12Fix for issue #185 "Shared Image reload() loses initial dimensions"ManoloFLTK
2021-02-11Fix for issue #185 in Fl_Shared_Image::reload()ManoloFLTK
This fix updates Fl_Shared_Image::reload() to account for the data_w() and data_h() image members.
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.
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

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
