2008-03-21 Tor Lillqvist <tml@novell.com> Import the GDI+ gdk-pixbuf loaders for Windows by Dominic Lachowicz and Alberto Ruiz into the GTK+ tree, from the gdip-pixbuf-loader module. * configure.in: Add switch --disable-gdiplus-loaders that disables building of the GDI+ loaders. When including loaders in the gdk-pixbuf library, either build in abll the GDI+ ones or none of them. Use just -DINCLUDE_gdiplus in $INCLUDED_LOADER_DEFINE to signal building them in. Add Automake conditionals BUILD_GDIPLUS_LOADERS to indicate whether the GDI+ loaders should be built and INCLUDE_GDIPLUS to indicate whether they should be built-in. For the rest of the changes, see gdk-pixbuf/ChangeLog. In gdk-pixbuf: * Makefile.am: Add the bits and pieces for the GDI+ loaders. When building GDI+ loaders don't build the traditional ones for the same formats. Always build the traditional PNG loader, though, as it isn't possible to read and write PNG tEXt chunks through GDI+, and GIMP at least needs that functionality in the gdk-pixbuf PNG loader. Either build all the GDI+ loaders (except the PNG one) into libgdk-pixbuf, or build them all as DLLs. I don't see any reason to enable cherry-picking among them whether to build in or not. * io-gdip-animation.c * io-gdip-animation.h * io-gdip-bmp.c * io-gdip-emf.c * io-gdip-gif.c * io-gdip-ico.c * io-gdip-jpeg.c * io-gdip-native.h * io-gdip-png.c * io-gdip-propertytags.h * io-gdip-tiff.c * io-gdip-utils.c * io-gdip-utils.h * io-gdip-wmf.c: New files. Note that io-gdip-png.c is not currently used. * gdk-pixbuf-io.c: Add the bits and pieces for built-in GDI+ loaders. svn path=/trunk/; revision=19914
