[evince] How to change the font color in evince

[Guoyu Ou <benogy gmail com>]

I am using debian 6.0 and the version of evince's source code is 2.30.3.

I modified the evince's source code in order to change the behavior of "Inverted Colors". When I select the "Inverted Colors", the background color will turn to light green instead of simply being inverted:

   libdocument/ev-document-misc.c:
   
      300 void
      301 ev_document_misc_invert_surface (cairo_surface_t *surface) {
            ......
      323         for (y = 0; y < height; y++) {
      324                 guchar *p = data + y * rowstride;
      325 
      326                 for (x = 0; x < width; x++) {
      327                         //p[0] = 255 - p[0];
      328                         //p[1] = 255 - p[1];
      329                         //p[2] = 255 - p[2];
      330                         // this will turn the background color to light green
      331                         p[0] = 204; // cc
      332                         p[1] = 232; // e8
      333                         p[2] = 207; // cf
      334                         p += 4;
      335                 }
      336         }

I didn't change the font color, but actually it turned white. I wonder whether there is a way to change the font color back? Sorry for my poor knowledge about cairo and gtk. Thanks.

Best regards,
