Hi,
I've just installed GEGL and BABL and started to do some test. For
example the following code :
#include <gegl.h>
gint main(gint argc, gchar **argv) {
GeglNode *gegl, *load, *size, *outp;
gegl_init(&argc, &argv);
gegl = gegl_node_new();
load = gegl_node_new_child(gegl, "operation", "load", "path", "data/test.jpg", NULL);
size = gegl_node_new_child(gegl, "operation", "scale", "x", 2.0, "y", 2.0, NULL);
outp = gegl_node_new_child(gegl, "operation", "png-save", "path", "data/ouput.png", NULL);
gegl_node_link_many(load, size, outp, NULL);
gegl_node_process(outp);
g_object_unref(gegl);
gegl_exit();
return 0;
}
This code just load an image (620x450) scale it by 2 in each dimension
and save it to an output jpeg file. So there is only simple operation on
small image but it take more than 30sec at 100% cpu on my Pentium4
3.4GHz !!!
So is it me who had done something wrong ar is GEGL and BABL so slow ?
For simplicity I've used the last released version of both and not SVN
version, but I don't think it will be so different. I suppose the error
come from elsewhere.
Both library are compiled with dry run of ./configure, make and make
install. The example program is compiled by :
cc -O3 -W -Wall `pkg-config --libs --cflags gegl` test.c -o test
and the output :
thomas:~/test$ time ./test
buffer-leaks: 3
real 32.007
user 31.366
sys 0.612
pcpu 99.90
So does any of you have an idea about what can cause this slow down ?
Thanks
Tom
