So, we need to define two auxiliary macros `\_inspicA` and `\_inspicB`. You can include more `\pdfximage` parameters (like `page=`) in the `\_picparams` macro. All `\inspic` macros are surrounded in `\hbox` in order user can write `\moveright\inspic ...` or something similar. \_cod \_fin ----------------------- \_def\_inspic{\_hbox\_bgroup\_isnextchar\_bgroup\_inspicB\_inspicA} \_def\_inspicA #1 {\_inspicB {#1}} \_def\_inspicB #1{% \_pdfximage \_ifdim\_picwidth=0pt \_else width\_picwidth\_fi \_ifdim\_picheight=0pt \_else height\_picheight\_fi \_picparams {\_the\_picdir#1}% \_pdfrefximage\_pdflastximage\_egroup} \_def\_picparams{} \_public \inspic ; \_doc ----------------------------- Inkscape is able to save a picture to `*.pdf` file and labels for the ficture to `*.pdf_tex` file. The second file is in \LaTeX/ format and it is intended to read immediately it after `*.pdf` in included in order to place labels of this ficture in the same font as document is printed. We need to read this \LaTeX/ file by plain \TeX/ macros when `\inkinspic` is used. These macros are stored in the `\_inkdefs` toknes list and it is used localy in the group. The solution is borrowed from OPmac trick 0032. \_cod ----------------------------- \_def\_inkinspic{\_hbox\_bgroup\_isnextchar\_bgroup\_inkinspicB\_inkinspicA} \_def\_inkinspicA #1 {\_inkinspicB {#1}} \_def\_inkinspicB #1{% \_ifdim\_picwidth=0pt \_setbox0=\_hbox{\_inspic{#1}}\_picwidth=\_wd0 \_fi \_the\_inkdefs \_opinput {\_the\_picdir #1_tex}% file with labels \_egroup} \_newtoks\_inkdefs \_inkdefs={% \_def\makeatletter#1\makeatother{}% \_def\includegraphics[#1]#2{\_inkscanpage#1,page=,\_end \_inspic{#2}\_hss}% \_def\_inkscanpage#1page=#2,#3\_end{\_ifx,#2,\_else\_def\_picparams{page#2}\_fi}% \_def\put(#1,#2)#3{\_nointerlineskip\_vbox to0pt{\_vss\_hbox to0pt{\_kern#1\_picwidth \_pdfsave\_hbox to0pt{#3}\_pdfrestore\_hss}\_kern#2\_picwidth}}% \_def\begin#1{\_csname _begin#1\_endcsname}% \_def\_beginpicture(#1,#2){\_vbox\_bgroup \_hbox to\_picwidth{}\_kern#2\_picwidth \_def\end##1{\_egroup}}% \_def\_begintabular[#1]#2#3\end#4{% \_vtop{\_def\\{\_cr}\_tabiteml{}\_tabitemr{}\_table{#2}{#3}}}% \_def\color[#1]#2{\_scancolor #2,}% \_def\_scancolor#1,#2,#3,{\_pdfliteral{#1 #2 #3 rg}}% \_def\makebox(#1)[#2]#3{\_hbox to0pt{\_csname _mbx:#2\_endcsname{#3}}}% \_sdef{_mbx:lb}#1{#1\_hss}\_sdef{_mbx:rb}#1{\_hss#1}\_sdef{_mbx:b}#1{\_hss#1\_hss}% \_sdef{_mbx:lt}#1{#1\_hss}\_sdef{_mbx:rt}#1{\_hss#1}\_sdef{_mbx:t}#1{\_hss#1\_hss}% \_def\rotatebox#1#2{\_pdfrotate{#1}#2}% \_def\lineheight#1{}% \_def\setlength#1#2{}% } \_public \inkinspic ; \_doc ---------------------------- `\pdfscale` and `\pdfrotate` macros are implemented by `\pdfsetmatrix` primitive. or rotating we need to knos values of sin, cos function.
