2021-05-31Windows platform: use GDI+ to antialias oblique lines and curves.ManoloFLTK
2021-05-28New virtual member function Fl_Graphics_Driver::colored_rectf().ManoloFLTK
2021-03-21Remove unnecessary system includes from public headersAlbrecht Schlosser
Add includes of system headers in the implementation files where necessary.
2021-03-11Unification of scaled coordinate calculations in class ↵ManoloFLTK
Fl_Scalable_Graphics_Driver Most coordinate calculations are done with the new inline function int Fl_Scalable_Graphics_Driver::floor(int coord) that is used by both the Windows and X11 platforms.

2021-02-27Rename fl_remove_scale() to fl_override_scale() as discussed in fltk.generalManoloFLTK
Re: Can custom box type functions handle their own high-DPI screen scaling?
2021-02-25Add fl_remove_scale()/fl_restore_scale() to transiently draw without scaling ↵ManoloFLTK
factor. This new API is a response to this message in fltk.general : Can custom box type functions handle their own high-DPI screen scaling?
2021-02-24Improve precision of GUI scaling for Windows platform.ManoloFLTK
2021-02-16Remove FL_CFG_SYS_WIN32 preprocessor variable from fl_draw_pixmap.cxxManoloFLTK
2021-02-16Use <config.h> when appropriate.ManoloFLTK
2021-02-13Remove compilation warnings issued by Visual Studio 2019.ManoloFLTK
2020-12-02Improve Fl_Graphics_Driver::cache_size() when GUI is scaled.ManoloFLTK
The change lets this function enlarge the size only when strictly necessary for image tiling.
2020-11-30Scaling for Windows and X11: support rectangular loops.ManoloFLTK
2020-11-19Rename private member function with trailing underscore.ManoloFLTK
2020-11-17Replace virtual Fl_RGB_Image::cache_size() by virtual Fl_Image::cache_size()ManoloFLTK
2020-11-12Fix for issue #155 - continuedManoloFLTK
Restores proper separation of what is in libfltk and what is in libfltk_images
2020-11-12Fix for issue #155 - continuedManoloFLTK
The issue lies in details how floating point scaled coordinates are converted to integer values and its impact on the drawing of large SVG images. This commit fixes the X11 platform. The macOS platform is immune because drawing uses floating point coordinates. The Windows platform still needs fixing.
2020-09-23Add Doxygen doc of "static unsigned Fl_Graphics_Driver::need_pixmap_bg_color"ManoloFLTK
2020-07-30Fix use of an SVG image in Fl_Tiled_Image when display is rescaled.ManoloFLTK
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.
2020-02-03Move fl_font(face, size) to fl_draw.cxxAlbrecht Schlosser
I believe this is a better place. Also: add FL_EXPORT since it's no longer inline.
2020-02-03Fix regression calling fl_font() w/o draw contextAlbrecht Schlosser
According to the documentation fl_font(face, size) may be called "outside a draw context if necessary to call fl_width()". This worked in 1.3.5 but did not in 1.4 (so far). I reworded the docs to make clear that other measurement functions can be called as well and refactored the code to make sure that fl_font(face, size) will open the display if necessary.
2020-01-20Improve documentation of clipping functionsAlbrecht Schlosser
Clarify functionality of fl_not_clipped() and fl_clip_box(). Add developer documentation for Fl_Graphics_Driver::clip_box(). Documentation only, no code changes in this commit.
2020-01-15Fix uninitialized vars in calls to fl_clip_box() (issue #6)Albrecht Schlosser
The main fixes are only to avoid static code analyzer warnings reported in issue #5, but there are also minor bug fixes included. These bug fixes are more of theoretical concerns though. Close #6.
2019-11-02Slightly simpler code to support fl_overlay_rect() on HighDPI screens.ManoloFLTK
2019-11-01Fix fl_overlay_rect() under X11 on HighDPI display.ManoloFLTK
The mandelbrot demo program is fixed.

2018-12-04Define useful implementations of Fl_Graphics_Driver::push_no_clip() and ↵ManoloFLTK
pop_clip().
2018-12-04Give a meaningful default implementation to a few more member functions of ↵ManoloFLTK
class Fl_Graphics_Driver.

2018-04-26Simplify API for Fl_Image_Surface::Fl_Image_Surface(int w, int h, int ↵Manolo Gouy
high_res, Fl_Offscreen off) with non-null offscreen. The caller no longer needs to call Fl_Image_Surface::get_offscreen_before_delete() before object deletion, because the object destructor knows the offscreen has not been created by the Fl_Image_Surface constructor. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12874 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

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

2018-03-22Rename Fl_Image::pixel_w() and pixel_h() to Fl_Image::data_w() and data_h().Manolo Gouy
The docs of class Fl_Image and of Fl_Image::scale() are beefed up. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12784 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
