2010-03-14Merge of branch-1.3-Fl_Printer, with the following main changes:Albrecht Schlosser
(1) adding Fl_Device class (and more) for device abstraction (2) adding Fl_Pinter class (and more) for printing support. Todo: Code cleanup, update dependencies, remove/replace test print window. I'm looking into converting the test window popup in a global shortcut that would pop up the print dialog now... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7263 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2009-06-29Fixed gray-scale images with alpha channel (STR #2105).Albrecht Schlosser
Note: Windows needs RGBA Bitmaps (4 bytes) to do alpha blending. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6804 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
2009-04-21Fixed gray scale w/alpha image drawing for Mac OS with Quartz (FLTK 1.1Albrecht Schlosser
with Quickdraw worked) in src/Fl_Images.cxx. Changed test/unittest_images.cxx to use Fl_RGB_Image::draw() to draw images with alpha channel, because the current version of fl_draw_image() supports alpha channels only on Mac. Tested on Windows[1], Linux, and Mac. [1] Windows with GDI drawing doesn't work yet for gray+alpha (STR 2105). To do: Check, if fl_draw_image() should support alpha channel images on all platforms or not at all. The current documentation mentions only RGB and gray scale images. IMHO the behavior is undefined for values of abs(d) == 2 and abs(d) > 3. See also fl_draw_image_mono(). git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6773 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2008-10-13Quickdraw removal: option removed from configure, all Qd code removed from ↵Fabien Costantini
sources. Also took this opportunity to sort the ifdef clauses so that USE_X11 shows first. Also added error pragma to enforce proper target checking, thus make even less assumptions. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@6423 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2006-09-15Implemented alpha blending for WIN32. I believe that I did it in a way that ↵Matthias Melcher
is compatible even with Windows 95, but please let me know if you have any concerns. Cygwin not tested, but hopefully OK. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@5430 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2006-06-04OS X Quartz: one pretty essential fix to the call order in Quartz context ↵Matthias Melcher
change which fixed a lot of warnings. I also added a file that helps tremondously to debug Core Graphics calls. This file is not compiled into the source tree by default, but the annotations in "src/cgdebug.h" explain the usage. In regard to CG Text drawing vs. the new ATSU Text drawing: I now remember why I did not ATSU in the beginning: STDU does not use the CG clipping area or text pen settings. So, if you plan on using the current SVN with --enable-quartz, please be aware that you will not have any text clipping or any other text color than black. Finally, I added code to FLTK on OS X that retreives the selection color from the system instead of assuming dark blue. I am not entirely confident about this change as it may require OS X 10.4 . Feedback appreciiated. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@5173 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2004-08-31Quartz for FLTK1.1Matthias Melcher
- Pixmaps now correctly support transparency/masking - subimage drawing aligned correctly - lines with a size over 1 always anti-alias - fl_begin_points/fl_end_points works - fixed refresh problem for multiple open windows Will check Linux compile right after this commit to make sure that I didn't destroy anything. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@3800 ea41ed52-d2ee-0310-a9c1-e6b18d33e121

2004-08-25Updated config stuff to allow for --enable-quartz ofr Mac OS X which inMatthias Melcher
turn defined USE_QUARTZ to 1 and defines __APPLE_QUARTZ__. If Quartz is not disabled, it will define __APPLE_QD__ for Quickdraw. I also replaced all relevand #ifdef __APPLE__ with #ifdef __APPLE_QD__ #elif defined(__APPLE_QUARTZ__). This does not affect the compile at this time and both version will generate the same Quickdraw code. I will start to replace all QD calls with Quartz calls for the remainder of the week until I can completely remove all QD calls from the Quartz branch. Thanks to Robert Smith for a great initial Quartz implementation. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@3782 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
