No spacing will be added at the top of the paragraph if the current y position is at (or above) the top margin of the page. (Default: 0.0) bottom_margin (float, optional): those two values determine how much spacing is added below the paragraph. No spacing will be added at the bottom if it would result in overstepping the bottom margin of the page. (Default: 0.0) indent (float, optional): determines the indentation of the paragraph. (Default: 0.0) bullet_string (str, optional): determines the fragments and text lines of the bullet. (Default: "") bullet_r_margin (float, optional): determines the spacing between the bullet and the bulleted line skip_leading_spaces (float, optional): removes all space characters at the beginning of each line. (Default: False) wrapmode (WrapMode): determines the way text wrapping is handled. (Default: None) first_line_indent (float, optional): left spacing before first line of text in paragraph. rUnable to nest paragraphs.) r'rUrVrErFrArBrCrGrDr:r) r rUrVrErArBrCrDr:rFrGrrrrr0s$  z!ParagraphCollectorMixin.paragraphcCs|jstdd|_dS)NzNo active paragraph to end.)rrr*rrrr_sz%ParagraphCollectorMixin.end_paragraphrc CsP|jdkrtd|jr |t|||||||||| | | d } |j| dS)Nrr) rsrrrrrArBrnrr)rrr_rrrw) r rrsrrrrrArBrnrrrrrrrs& zParagraphCollectorMixin.image)N)N) NNFrrrr@NNr) NNNFFrrNNN)rrrrr3r rr^rdrrrprzr0r_rr,rrr#rr<sb    0 rc@s@eZdZdZddZddZddZdd Zd d Zd d Z dS) TextRegionz3Abstract base class for all text region subclasses.cCs tdS)aZ Return the horizontal extents of the current line.
