The overlap is specified relative to the minimum height of both characters. :param char_margin: If two characters are closer together than this margin they are considered part of the same line. The margin is specified relative to the width of the character. :param word_margin: If two characters on the same line are further apart than this margin then they are considered to be two separate words, and an intermediate space will be added for readability. The margin is specified relative to the width of the character. :param line_margin: If two lines are are close together they are considered to be part of the same paragraph. The margin is specified relative to the height of a line. :param boxes_flow: Specifies how much a horizontal and vertical position of a text matters when determining the order of text boxes. The value should be within the range of -1.0 (only horizontal position matters) to +1.0 (only vertical position matters). You can also pass `None` to disable advanced layout analysis, and instead return text based on the position of the bottom left corner of the text box. :param detect_vertical: If vertical text should be considered during layout analysis :param all_texts: If layout analysis should be performed on text in figures. ?@皙?F line_overlap char_margin line_margin word_margin boxes_flowNdetect_vertical all_textsr!c||_||_||_||_||_||_||_|dSr#)r>r?r@rArBrCrD _validate)r%r>r?r@rArBrCrDs r&r'zLAParams.__init__LsP)&&&$." r(c|jUd}t|jttfst |d|jcxkrdksnt |dSdS)Nz@LAParam boxes_flow should be None, or a number between -1 and +1r-)rBr.r7floatr r )r%boxes_flow_err_msgs r&rFzLAParams._validate`s{ ? &R te == 7"#5666----A----#$6777 ' & .-r(c Nd|jdd|jdd|jdd|jd S)Nz)r?r@rArDr%s r&__repr__zLAParams.__repr__jsZ -d&6 > - -+ 3 - -+ 2 - - - - - r()r;r<r;r=r;FFr!N) r4r5r6__doc__rIboolr'rFstrrNr8r(r&r:r:0s:"   #& %    DL  (8888 #      r(r:c"eZdZdZdeddfdZdS)r*z)Interface for things that can be analyzedlaparamsr!NcdS)zPerform the layout analysis.Nr8r%rTs r&analyzezLTItem.analyzevsr()r4r5r6rPr:rWr8r(r&r*r*ss<33++T++++++r(r*c*eZdZdZdefdZdefdZdS)LTTextz#Interface for things that have textr!cLd|jjd|dSN< rL) __class__r4get_textrMs r&rNzLTText.__repr__}s(A4>*AAT]]__AAAAr(ct)zText contained in this objectNotImplementedErrorrMs r&r_zLTText.get_texts!!r(N)r4r5r6rPrRrNr_r8r(r&rYrYzsU--B#BBBB"#""""""r(rYceZdZdZdeddfdZdefdZdede fdZ dede fd Z dede fd Z dede fd Z deddfd Zde fd Zddde fdZdddefdZdddefdZddde fdZdddefdZdddefdZdS) LTComponentzObject with a bounding boxbboxr!Ncdt|||dSr#)r*r'set_bboxr%res r&r'zLTComponent.__init__s, dr(cLd|jjdt|jdSr[)r^r4rrerMs r&rNzLTComponent.__repr__s*C4>*CCXdi-@-@CCCCr(_ctr#r r%rjs r&__lt__zLTComponent.__lt__r(ctr#rlrms r&__le__zLTComponent.__le__ror(ctr#rlrms r&__gt__zLTComponent.__gt__ror(ctr#rlrms r&__ge__zLTComponent.__ge__ror(c|\}}}}||_||_||_||_||z |_||z |_||_dSr#)x0y0x1y1widthheightre)r%rerwrxryrzs r&rgzLTComponent.set_bboxsMRR"W 2g  r(c.|jdkp |jdkSNr)r{r|rMs r&is_emptyzLTComponent.is_emptyszQ2$+"22r(r)ct|ts$Jtt||j|jko|j|jkSr#)r.rdrRtyperwryr%r)s r& is_hoverlapzLTComponent.is_hoverlapI#{++;;Sc^^;;+v 6TW%66r(c*t|ts$Jtt|||rdSt t |j|jz t |j|jz Sr~ r.rdrRrrminabsrwryrs r& hdistancezLTComponent.hdistancez#{++;;Sc^^;;+   C  E1s47SV+,,c$'CF2B.C.CDD Dr(c*t|ts$Jtt|||rDt t |j|jz t |j|jz SdSr~rrs r&hoverlapzLTComponent.hoverlapy#{++;;Sc^^;;+   C  s47SV+,,c$'CF2B.C.CDD D1r(ct|ts$Jtt||j|jko|j|jkSr#)r.rdrRrrxrzrs r& is_voverlapzLTComponent.is_voverlaprr(c*t|ts$Jtt|||rdSt t |j|jz t |j|jz Sr~ r.rdrRrrrrrxrzrs r& vdistancezLTComponent.vdistancerr(c*t|ts$Jtt|||rDt t |j|jz t |j|jz SdSr~rrs r&voverlapzLTComponent.voverlaprr()r4r5r6rPrr'rRrNobjectrQrnrqrsrurgrrrIrrrrrr8r(r&rdrds$$TdD#DDDD4444Td3$33337}77777E]EuEEEEMe7}77777E]EuEEEEMer(rdceZdZdZ ddedeedededed edzd edzd ee dzd e e e fdzd dfdZ d e fdZdS)LTCurvezA generic Bezier curve The parameter `original_path` contains the original pathing information from the pdf (e.g. for reconstructing Bezier Curves). `dashing_style` contains the Dashing information if any.
