You can find + precompiled libraries and headers on the GTK download page for + Windows (http://www.gtk.org/download-windows.html). + + Versions 1.4.0 and later of libpng are binary incompatible with + earlier versions, so Emacs will only look for libpng libraries which + are compatible with the version it was compiled against. That + version is given by the value of the Lisp variable `libpng-version'; + e.g., 10403 means version 1.4.3. The variable `dynamic-library-alist' + is automatically set to name only those DLL names that are known to + be compatible with the version given by `libpng-version'. If PNG + support does not work for you even though you have the support DLL + installed, check the name of the installed DLL against + `dynamic-library-alist' and the value of `libpng-version', and + download compatible DLLs if needed. + * Experimental SVG support SVG support is currently experimental, and not built by default. |
