For a long time pdflatex has offered the command \pdfannot for inserting arbitrary PDF annotations. However, the command is presented in a form where additional knowledge of the definition of the PDF format is indispensable. This package is an answer to the – occasional – questions in newsgroups, about how one could use the comment function of Adobe Reader. At least for the writer of LATEX code, the package offers a convenient and user-friendly means of using \pdfannot to provide comments in PDF files. Since version v1.1, pdfcomment.sty also supports: LaTeX -> dvips -> ps2pdf, LaTeX -> dvipdfmx and XeLaTeX. Unfortunately, support of PDF annotations by PDF viewers is sparse to nonexistent. The reference viewer for the development of this package is Adobe Reader. License: LPPL New in v1.4: - new annotation type: PDF sideline, line, polyline, polygon, square and circle annotation -> \pdfsidelinecomment, \pdflinecomment (type=line|polyline|polygon), \pdfsquarecomment, \pdfcirclecomment - new options: font, fontsize, fontcolor, borderstyle, dashstyle, bse, bsei, line, type, lineend, linebegin, icolor, caption, captionhoffset, captionvoffset
