The parent text block consists of lines with similar line spacing, while lines in other paragraph might be counted when the paragraph spacing is relatively small. So, it's necessary to split those lines by checking the text contents. .. note:: Considered only normal reading direction, from left to right, from top to bottom. rcss,|]}|djd|djdVqdS)rrNbboxr rowrrrr>*z1Lines.split_vertically_by_text..Ncss,|]}|djd|djdVqdS)rrNr"r$rrrr?r&Fr!rrg?T)group_by_physical_rowslenmaxsumr tupler ZSENTENSE_END_PUNCtextstripendswithr#rr)rrr rowsnumWHreslinesZpuncZ start_of_paraZ end_of_paraZ start_of_senZ end_of_senr%wrrrsplit_vertically_by_text-s<         zLines.split_vertically_by_textdelete_end_line_hyphenc sdddtjDfdd}t|jddD]T\}}|jd}t|ts)q|j}|s/q|d}|j|djd }t|tsCq|j} | sIq| d } |r]|j d r]| j r]d|_ ||j rn|| j rn|j d 7_ qdS) zAdjust word at the end of line: # - it might miss blank between words from adjacent lines # - it's optional to delete hyphen since it might not at the the end of line after conversion css|] }|dkr|VqdS)-Nr)r crrrrosz)Lines.adjust_last_word..cs|p |o |vSr )isalnum)r;Zpunc_ex_hyphenrris_end_of_english_wordpsz6Lines.adjust_last_word..is_end_of_english_wordNr!rrr: ) joinstring punctuation enumeraterr isinstancercharsr;r/islower) rr8r>ir Zend_spanZ end_charsZend_charZ start_spanZ start_charsZnext_start_charrr=radjust_last_wordis.     zLines.adjust_last_wordcCsd}|jD]A}|tj}|j|s|jj|jjkr|Sqg}|jD]}t |t r1| |q$| ||j }||d}q$|j|q|S)zParse text format with style represented by rectangle shape.

Args: bbox (Rect): bbox of parent layout, e.g. page or cell. line_break_width_ratio (float): user defined threshold, break line if smaller than this value. line_break_free_space_ratio (float): user defined threshold, break line if exceeds this value. Hard line break helps ensure paragraph structure, but pdf-based layout calculation may change in docx due to different rendering mechanism like font, spacing. For instance, when one paragraph row can't accommodate a Line, the hard break leads to an unnecessary empty row. Since we can't 100% ensure a same structure, it's better to focus on the content - add line break only when it's necessary to, e.g. short lines. rrr'rrr!rrN) parentrKabsr#r( line_break alignmentrRIGHTZCENTER)rr#rQrblockidx0idx1Z block_widthZ layout_widthrVr0r5r end_lineZ free_spacerrrparse_line_breaks$  zLines.parse_line_breakline_separate_thresholdc s|jjrdnd\}fdd}tt||j}ttdd|_js*dSj}t |jD]0\}}|j|}||krFd|_ ||jdkrPdS| |j|dr_|j|nj}q4dS) zCalculate tab stops for parent block and whether add TAB stop before each line.
