uninitialized (or stupid) values returned by WordFontAttributes if word contains no text #1334

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When no text is recognised under the current word, pointsize (and perhaps other 
attrs) returned from WordFontAttributes are uninitialized. They should be 
sensible defaults or throw an error. It is strange that at the same time 
res_it->Empty(RIL_WORD) is not being hit - earlier in the code we have a test 
for that...

          const char *font_name = res_it->WordFontAttributes(&bold, &italic, &underlined,
                                            &monospace, &serif, &smallcaps,
                                            &pointsize, &font_id);

          const char *text = res_it->GetUTF8Text(RIL_WORD);
          cout << pointsize << "pt " << strlen(text) << endl;

outputs:

Can you post a test case (at least image) for this issue?
