I tried so, but it still doesn't show up with an image center at (0,0). The same data shows a center at (0,0) in the fft module.
thats how I fetch real data and generate the fft data and display them: [code] gwy_app_data_browser_get_current(GWY_APP_DATA_FIELD, &data_field, 0); data_field_fft_r = gwy_data_field_new_alike(data_field, FALSE); gwy_data_field_2dfft(data_field,NULL,data_field_fft_r,data_field_fft_i,GWY_WINDOWING_NONE,GWY_TRANSFORM_DIRECTION_FORWARD,GWY_INTERPOLATION_ROUND,TRUE,1) ; gwy_data_field_fft_postprocess(data_field_fft_r,TRUE) ; gwy_data_field_data_changed(data_field_fft_r); data[1] = gwy_container_new(); data_view[1] = GWY_DATA_VIEW(gwy_data_view_new(data[1])); gwy_data_view_set_data_prefix(data_view[1], "/0/data"); gwy_container_set_boolean_by_name(data[1], "/0/data/realsquare", TRUE); gwy_container_set_int32_by_name(data[1], "/0/base/range-type", GWY_LAYER_BASIC_RANGE_FIXED); gdouble min, max ; gwy_data_field_get_min_max (data_field_fft_r,&min,&max); gwy_container_set_double_by_name(data[1], "/0/base/min", 0.1*max); gwy_container_set_double_by_name(data[1], "/0/base/max", 0.2*max); g_assert( widget = GTK_WIDGET(gtk_builder_get_object(builder, "viewport2")) ); gtk_container_add(GTK_CONTAINER(widget), GTK_WIDGET(data_view[1])); [/code] On 0, "David Nečas (Yeti)" <[email protected]> wrote: > On Mon, Sep 15, 2014 at 03:17:55PM +0200, Mathias Müller wrote: > > my offsets: > > > > -2,565e+09 and 2,555e+09 > > > > They seem to be what you expect them to be. > > > > in the image: left edge -> x = 5,58952e+06 > > right edge -> x = 5,11441e+09 > > OK, if you are already displaying the same field, you just need to call > gwy_data_field_data_changed() so that views take notice that it has > changed. > > Regards, > > Yeti ------------------------------------------------------------------------------ Want excitement? Manually upgrade your production database. When you want reliability, choose Perforce. Perforce version control. Predictably reliable. http://pubads.g.doubleclick.net/gampad/clk?id=157508191&iu=/4140/ostg.clktrk _______________________________________________ Gwyddion-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/gwyddion-users
