ManoloFLTK 569fec25e0 Unification of scaled coordinate calculations in class 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.

ManoloFLTK 231159e16c Fix for issue #155 - continued
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.

Albrecht Schlosser f09e17c3c5 Remove $Id$ tags, update URL's, and more
- 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.

Manolo Gouy 16705ef734 Image drawing: simplify the code organisation to better support 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)

Manolo Gouy 458d063643 Image classes: memorise the width and the height of the cached form of the image to support GUI scaling
git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12811 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2018-03-28 13:00:12 +00:00
Manolo Gouy 916b44e361 New member function Fl_Image::scale(int width, int height) to set the FLTK 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.

Albrecht Schlosser 52ae3582a2 Replace "WIN32" with "_WIN32" or "Windows".
Replace compiler/preprocessor/platform macro "WIN32" with "_WIN32".
Replace "WIN32" in text and documentation with "Windows".
Replace "MSWindows" with "Windows".

To do: README.Windows.txt (and maybe other documentation as well)
needs updates.

Manolo Gouy c472d5d8b7 Fix fl_read_image() under MacOS platform when GUI is rescaled.
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.
