5.5Decoration: Soft Clipping

  • \usepgfplotslibrary{decorations.softclip} % and plain

  • \usepgfplotslibrary[decorations.softclip] % Cont

  • \usetikzlibrary{pgfplots.decorations.softclip} % and plain

  • \usetikzlibrary[pgfplots.decorations.softclip] % Cont

    • Activates decoration=softclip.

    A “soft clip” is a part of an input path, namely that part which is inside of the “clip path”. This is typically known as clipping: you set \clip (math image)path(math image); and all following paths are clipped against (math image)path(math image). Soft-clipping is similar, but instead of installing a low-level clip path, it modifies the input path in a way such that only parts inside of (math image)path(math image) remain. This makes a difference if decorations are to be applied. It also makes a difference for fill between/soft clip.

    Note that this library is loaded implicitly by the fillbetween library in order to address its fill between/soft clip key.

    Attention: this library is considered to be experimental. It will work for paths which are similar to a plot, i.e. paths which do not intersect themselves and which have a clear direction. The library might fail, in general.

    An application could be to draw a path twice, but the second time should only affect portions of the path:

    (-tikz- diagram)

    \begin{tikzpicture} \draw [ postaction={decorate,draw,ultra thick}, decoration={ soft clip,soft clip path={ (1.5,-1) rectangle (4,2) }, }, ] (0,0) -- (1,1) -- (2,1) -- (3,0); \end{tikzpicture}

    The soft clip feature is tailored for use with fill between. Please refer to the documentation of fill between/soft clip for more examples and explanation on soft-clipping.

  • /pgf/decoration/soft clip path=(math image)corner1(math image) rectangle (math image)corner2(math image)

    • Assigns the path which is to be used for the soft clip decoration. This argument is mandatory in order to apply a soft clip decoration.

    Please refer to the documentation of fill between/soft clip for details; it has the same syntax and a similar motivation.

  • /pgf/decoration/every soft clipped path(style, no value)

    • A style which is applied just before the reduced path is generated.
