2022-12-09New Fl_ICO_Image class to read Windows .ico icon filesManoloFLTK
Many thanks to @darealshinji for contributing all the code for this new FLTK image class (see branch Fl_ICO_Image of https://github.com/darealshinji/fltk).
2021-04-07Remove static variable, fix gcc warning [-Wclobbered] (#203)Albrecht Schlosser
PR #203 "Multithread fix for PNG loading" includes a suggested fix that moves the variable fp to the Fl_PNG_Image structure. This commit fixes the threading issue by allocating the variable fp with new, avoiding the [-Wclobbered] warning w/o using a static var. The same issue is now also fixed in Fl_JPEG_Image.
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.

2017-09-10Fix compiler warning and potential error in PNG error handling.Albrecht Schlosser
Compilation with gcc -Wall -Wextra displayed the following warning: Fl_PNG_Image.cxx: In member function ‘void Fl_PNG_Image::load_png_(const char*, const unsigned char*, int)’: Fl_PNG_Image.cxx:118:9: warning: variable ‘fp’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Wclobbered] Making the variable static and initializing it properly avoids this potential error in the PNG lib's error handling. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12439 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
