hello, I am having trouble to save gegl operations to repeat them later. I think, that gegl_node_to_xml is the operation I am looking for, but this can be wrong.
I wrote this small program: #include <stdio.h> #include <gegl.h> gint main (gint argc, gchar **argv) { GeglNode *gegl, *gn_load, *gn_save, *gn_op; gchar* xmltext; g_thread_init (NULL); gegl_init (&argc, &argv); gegl = gegl_node_new (); gn_load = gegl_node_new_child(gegl, "operation", "gegl:load", "path", "bsp-900x600.jpg", NULL); gn_save = gegl_node_new_child(gegl, "operation", "gegl:jpg-save", "path", "out.jpg", NULL); gn_op = gegl_node_new_child(gegl, "operation", "gegl:unsharp-mask", "std-dev", 1.2, "scale", 8.0, NULL); gegl_node_link_many (gn_load, gn_op, gn_save, NULL); gegl_node_process (gn_save); gegl_node_to_xml(gegl, xmltext); printf("xmltext: %s\n", xmltext); g_object_unref (gegl); gegl_exit (); return 0; } These are the library version ldd told me: linux-gate.so.1 => (0xb78a1000) libgegl-0.1.so.0 => /usr/lib/libgegl-0.1.so.0 (0xb782c000) libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb76cb000) libgobject-2.0.so.0 => /usr/lib/i386-linux-gnu/libgobject-2.0.so.0 (0xb7683000) libgthread-2.0.so.0 => /usr/lib/i386-linux-gnu/libgthread-2.0.so.0 (0xb767e000) libgio-2.0.so.0 => /usr/lib/i386-linux-gnu/libgio-2.0.so.0 (0xb757b000) libgmodule-2.0.so.0 => /usr/lib/i386-linux-gnu/libgmodule-2.0.so.0 (0xb7577000) librt.so.1 => /lib/i386-linux-gnu/librt.so.1 (0xb756e000) libglib-2.0.so.0 => /lib/i386-linux-gnu/libglib-2.0.so.0 (0xb7496000) libbabl-0.1.so.0 => /usr/local/lib/libbabl-0.1.so.0 (0xb7448000) libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xb7422000) libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xb7409000) /lib/ld-linux.so.2 (0xb78a2000) libresolv.so.2 => /lib/i386-linux-gnu/libresolv.so.2 (0xb73f4000) libz.so.1 => /lib/i386-linux-gnu/libz.so.1 (0xb73de000) libselinux.so.1 => /lib/i386-linux-gnu/libselinux.so.1 (0xb73c3000) libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xb73bf000) libpcre.so.3 => /lib/i386-linux-gnu/libpcre.so.3 (0xb7380000) And I hoped, that xmltext would be string, containing a xml tree for this little gegl operation. unfortunally all I got where a handful of binary bytes - not the xml text (somthing like "<gegl>....</gegl>") I hoped for. Any hints for me? thanks in advance Joerg _______________________________________________ Gegl-developer mailing list Gegl-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
