You will see how the hocr file is built with lines like this:
api/baseapi.cpp: hocr_str.add_str_int("\n <p class='ocr_par'
dir='ltr' id='par_",
Going out on a limb, I grepped the tree for ocr_float, and got no hits. A
closer look at the code might turn up something, so have a look.
What I see in api/baseapi.cpp is:
'ocr_page'
'ocr_carea'
'ocr_par'
'ocr_line'
'ocrx_word'
You can also look in api/renderer.cpp :
bool TessHOcrRenderer::BeginDocumentHandler() {
..
" <meta name='ocr-capabilities' content='ocr_page ocr_carea ocr_par"
" ocr_line ocrx_word");
