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

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

2001-12-19Multiple bug fixes from Sebastien:Michael R Sweet
- Fl_GIF_Image and Fl_PNG_Image didn't close the file before calling Fl::error(). - Fl_Help_View didn't clear the line array in Fl_Help_Block, and Fl_Help_Block::font and ::size were not used. - Fl_Shared_Image::get() didn't return NULL if the image could not be loaded. - Switched to more efficient code for Fl_Tiled_Image::color_average() and ::desaturate(). - Don't delete children in Fl_Text_Display since the group will do it. - Fixes to filename_isdir(), filename_absolute(), and filename_relative(). - Was using numbers instead of define constants for some OpenGL stuff under WIN32. - Wasn't exporting threading functions under WIN32. - The Fl_Widget destructor now removes from the parent to avoid a Purify error since the old widget would be referenced by the parent when it was destroyed; this has no apparent performance impact since Fl_Group::clear() sets children_ to 0, making Fl_Group::remove() very fast... - WIN32 font enumeration datatype fixes... git-svn-id: file:///fltk/svn/fltk/branches/branch-1.1@1878 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
