This private method assembles the PDF content stream operators to draw the provided text within the specified rectangle. It handles text positioning, font application, color, and special formatting like selected text. Args: text: The text to be rendered in the form field. selection: An optional list of strings that should be highlighted as selected. font: The font to use. font_glyph_byte_map: An optional dictionary mapping characters to their byte representation for glyph encoding. font_name: The name of the font resource to use (e.g., "/Helv"). font_size: The font size. If 0, it is automatically calculated based on whether the field is multiline or not. font_color: The color to apply to the font, represented as a PDF graphics state string (e.g., "0 g" for black). is_multiline: A boolean indicating if the text field is multiline. alignment: Text alignment, can be TextAlignment.LEFT, .RIGHT, or .CENTER. is_comb: Boolean that designates fixed-length fields, where every character fills one "cell", such as in a postcode. max_length: Used if is_comb is set. The maximum number of characters for a fixed- length field. Returns: A byte string containing the PDF content stream data. rg@@>/B/Ir rg@FrQzLength of text z exceeds maximum length (z) of field, input truncated.czg|]7\}}|ptk|zdz |f8SrQ)r\rZ).0indexcharrFrGrtrKs r- zITextStreamAppearance._generate_appearance_stream_data..sbWWW%EZ=T3t994U4U%% 1D85V4U4Ur,cJg|]}|zdz |f Sr{)rZ)r|linerFrGs r-rzITextStreamAppearance._generate_appearance_stream_data..sO@@@%% 1D8@@@r,rOrPrSz Tf z q /Tx BMC q z re W BT z1 z re 0.5 0.5 0.5 rg s rz Td cbg|]+}||d,S)z utf-16-be)getencode)r|crns r-rzITextStreamAppearance._generate_appearance_stream_data..'sC)))FG#''188K+@+@AA)))r,c3<K|]}t|dkVdS)r N)r\)r|rs r- zHTextStreamAppearance._generate_appearance_stream_data..*s,5513q66Q;555555r, Tj (s) Tj s ET Q EMC Q )r8r isinstancer%rfont_descriptorbboxr maxrheightwidthDEFAULT_FONT_SIZE_IN_MULTILINEr]rZr^minr\r r!rYrTrUascentrr?rBrAanyr[hex)$r9rKrmrFrnrorGrprqrrrsrtrrHfactormarginrJrIrLlinesmax_vertical_sizetext_width_unscaledmax_horizontal_sizey_offsetdefault_appearance ap_stream current_x_pos line_number line_widthrdesired_abs_x_start cell_widthcentering_offset_in_cell x_rel_offset y_rel_offset encoded_lines$ ` `` ` ` r- _generate_appearance_stream_dataz5TextStreamAppearance._generate_appearance_stream_datasVL* 17R i ' ' 3' 22I.3A69M9RST9UUY__l/<??QT\.7;; '!f*4 oF 2  >>M %$  B: #'#3#3" !$$ yy%1>$A!&*ood&;&;d&B#&15H5MA&N#!#c*;=P&Q&QS`"a"acdee - 94@A  @ c$ii*44mdmmZmmm WWWWWWW"+4WWWEE @@@@@,,tT2288>>@@@E  f '&043G3LQ3OR[3[^d3ddHH,1E1Ly1X[_1_"_cd!deH )GGIGG:GG 1q6z 1 1F 1 1[ 1 1< 1 1, 1 1 1 &((  ! /8/?/?3 G3 G +K+*d TY..@[9%<~%MNQRR@@ *@@-6]@@);@@@&((  *+  1: 1&_z9 -7,Cq+H('2Z'?C[&[##m111&/o &BZ&O##m222'0'Cq&H##&,qj#/>L#$La'  <" !*{^;  L>><>>>EEGG GI0M))))KO)))L55 55555 GTSXXl%;%;$@$@$B$B$I$I$K$KKiWW TCHH\$:$::YFF '' r,rRr0 font_resourcec t||rtj|nt d|dt d}t d} tditttdtdd| j | j  }d } tjt r|jd nCt%jt)fd |Drd } n#t*$rd } YnwxYw| st d |dt tjt r&fdjD}n~djD}djD}jD]\}}|||||<||||||||| | |  }|t7|t9t;||t=d<t?t=dt?t=|tA|d|ii|t=d<dS)a Initializes a TextStreamAppearance object.

This class method is a factory for creating a `TextStreamAppearance` instance by extracting all necessary information (bounding box, font, text content, etc.) from the PDF field and annotation dictionaries. It respects inheritance for properties like default appearance (`/DA`). Args: acro_form: The root AcroForm dictionary from the PDF catalog. field: The field dictionary object. annotation: The widget annotation dictionary object associated with the field. user_font_name: An optional user-provided font name to override the default. Defaults to an empty string. user_font_size: An optional user-provided font size to override the default. A value of -1 indicates no override.
