+ \item Make your presentations stand out.
+ \item Turn any counter into a picture.
+\stopitemize
+
+\page
+
+The above effect was achieved by first defining a \command{visualitem} counter
+and a symbol \command{visual} that uses that counter:
+
+\typebuffer[visual]
+
+and then using the symbol \command{visual} in an itemization:
+
+\starttyping
+\startitemize[visual, ...]
+ \item ...
+ \item ...
+\stopitemize
+\stoptyping
+
+\page
+
+Notice the counter used for page numbering? That was achieved by first defining
+a \command{visualpage} counter:
+
+\typebuffer[page]
+
+and setting it as the footer text:
+
+\typebuffer[pagenumber]
+
+\page
+
+The above examples show the basic usage of the modules. The module provides two
+commands: \type{\definevisualcounter} to define a visual counter
+
+\starttyping
+\definevisualcounter
+ [...] % [[\comment{name of the counter}]]
+ [...] % [[\comment{optional name of the parent counter} ]]
+ [
+ ...=..., % [[\comment{key-value settings} ]]
+ ]
+\stoptyping
+
+and \type{\usevisualcounter} to use an already defined counter
+
+\starttyping
+\usevisualcounter
+ [...=...] % [[\comment{key-value settings}]]
+ {...} % [[\comment{name of the counter}]]
+\stoptyping
+
+\section {So, how do I use this?}
+
+Visual counters are defined and used in two ways:
+\startitemize[visual, broad, joinedup]
+ \item Using a low level interface that explicitly sets the current values of
+ the counter, last count, the \METAPOST\ graphic that draws the counter, and
+ the color palette.
+ \item Using higher-level interfaces built on top of the low-level interface
+ that allows you to specify a \emph{structure counter} like those used for
+ page numbering, itemizations, descriptions, etc.
+\stopitemize
+
+\page
+
+\subsection {The low-level interface}
+
+To begin with, lets not worry about how to define \METAPOST\ graphics that draw
+the counter. The module provides a predefined set of \command{visualcounter}s,
+and, for now, we'll just use those: the \command{scratchmarks} counter. Details
+on defining new counters are explained later.
+
+\startbuffer[scratchmarks]
+\usevisualcounter[n=6, last=12]{scratchmarks}
+\stopbuffer
+
+Suppose that I want to show that I am on page 6 out of 12 pages:
+
+\startmiddlealigned
+ \getbuffer[scratchmarks]
+\stopmiddlealigned
+
+which uses a predefined counter \command{scratchmarks} and was typed as follows:
+
+\typebuffer[scratchmarks]
+
+The counter may be made smaller
+
+\startbuffer[smaller]
+\setupvisualcounter[scratchmarks]
+ [width=1pt, height=8pt, distance=2pt]
+\stopbuffer
+
+\startmiddlealigned
+ \getbuffer[smaller,scratchmarks]
+\stopmiddlealigned
+
+or may use a different color palette
+
+\startbuffer[palette]
+\setupvisualcounter[scratchmarks][palette=brightred]
+\stopbuffer
+
+\startmiddlealigned
+ \getbuffer[brightred,palette,scratchmarks]
+\stopmiddlealigned
+
+\page
+
+These settings are changed using \command{\setupvisualcounter}. In particular, to
+get a small counter, use:
+
+\typebuffer[smaller]
+
+and to change the color palette, use:
+
+\typebuffer[palette]
+
+where the \type{brightred} palette was defined as
+
+\typebuffer[brightred]
+
+\subsection {The high-level interface}
+
+The high level interface is useful to display a \CONTEXT{} counter. Rather than
+manually setting the value of \options{n}, \options{last}, \options{text}, and
+\options{maxtext} (the last two are used only by a few counters), simply set the
+value of a \options{counter} and the other values are automatically generated.
+As an example, recall the set up for displaying the page numbers in the footer:
+
+\typebuffer[page]
+
+In the above example, \command{userpage} is the name of the counter that keeps
+track of the user page number.
+
+\page
+
+A list of some commonly used \CONTEXT{} counters is given below:
+
+\startbuffer[internal] counter=\getvalue{v_strc_itemgroups_counter},
+\stopbuffer
+
+
+\starttabulate[|l|l|]
+ \NC Page numbers \NC \type{userpage} \NC \NR
+ \NC Item group numbers
+ \NC \type{\v_strc_itemgroups_counter}\footnote[internal]
+ {Macros names with underscore are internal \CONTEXT{} macros, and generally are
+ not meant to be used in user code. The easiest way to set the value of
+ \options{counter} to \options{\v_strc_itemgroups_counter} is to use:
+ \typebuffer[internal]} \NC \NR
+ \NC Enumeration number\NC name of the enumeration \NC \NR
+\stoptabulate
+
+
+\section {Changing the color of counters}
+
+All counters use three colors: \command{past} to display past counters,
+\command{active} to display current counter, and \command{future} to display
+future counters. To change the color scheme, first define a new color palette
+(which is misspelled in \CONTEXT{} is \command{colorpalet}):
+
+\starttyping
+ \definecolorpalet
+ [...], % [[\comment{Name of the color palette}]]
+ [
+ past=..., % [[\comment{any previously defined \CONTEXT{} color}]]
+ active=..., % [[\comment{any previously defined \CONTEXT{} color}]]
+ future=..., % [[\comment{any previously defined \CONTEXT{} color}]]
+ ]
+\stoptyping
+
+\page
+
+and then set the color palette of a particular counter either using
+
+\starttyping
+ \definevisualcounter
+ [...] % [[\comment{name of the counter}]]
+ [...] % [[\comment{optional name of the parent counter} ]]
+ [
+ ...,
+ palette=..., % [[\comment{name of a previously defined} \options{colorpalet}]]
+ ...
+ ]
+\stoptyping
+
+or using
+
+\starttyping
+ \setupvisualcounter
+ [...] % [[\comment{name of the counter}]]
+ [
+ ...,
+ palette=..., % [[\comment{name of a previously defined} \options{colorpalet}]]
+ ...
+ ]
+\stoptyping
+
+\section {Changing the size of the counters}
+
+All predefined counters have tunable parameters (such as \options{width},
+\options{height}, and \options{distance}) that change the size of the counter.
+The default sizes are given in terms of \options{EmWidth} or \options{ExHeight};
+so they adapt to the size of the surrounding text.
+
+\section {Changing the style of text displayed in the counters}
+
+Some visual counters (currently, only the \command{countdown} counter) also
+display text. The style of this text may be set using:
+
+
+\starttyping
+ \setupvisualcounter
+ [...] % [[\comment{name of the counter}]]
+ [
+ ...,
+ style=..., %[[ \comment{any valid \CONTEXT{} style}]]
+ color=..., %[[ \comment{any valid \CONTEXT{} color}]]
+ ...
+ ]
+\stoptyping
+
+Note that changing the font size in the \options{style} affects the value of
+\options{EmWidth} and \options{ExHeight} and therefore also scales the counter
+appropriately. If this is not desirable, then you also need to set the size of
+the counter in dimensions that are independent of bodyfontsize.
+
+\section {Predefined counters}
+
+The \command{visualcounter} module provides the following predefined counters:
+
+\startnarrower
+\placelist[visualsection][criterium=local, alternative=f]
+\stopnarrower
+
+\page
+
+\visualsection {The \command{scratchmarks} counter}
+
+The \command{scratchmarks} counter is inspired by the \command{fuzzycount}
+counter that is part of the \CONTEXT's metapost library \command{txt}. The output
+looks as follows:
+
+\definevisualcounter
+ [dummy]
+ [scratchmarks]
+
+\showcounter[4]
+
+\blank[2*big]
+
+The \command{scratchmarks} counter has the following tunable parameters:
+\startitemize[packed, joinedup]
+ \item \options{width} (default \options{3bp}): the width of each stroke
+ \item \options{height} (default \options{3ExHeight}):
+ the length of the marker (and strictly speaking, not
+ the height; the real height is $\options{height}×\sin(\options{angle})$).
+ \item \options{distance} (default \options{0.5EmWidth}):
+ the distance between two successive markers. The
+ distance is measured from the middle of one marker to the middle of the
+ other (that is, it does not take the width of the stroke into account).
+ \item \options{angle} (default \options{75}): the angle of the forward
+ markers. The angle of the backward marker is \command{-angle}.
+ Only angles between \options{-90} and \options{90} give proper output.
+\stopitemize
+
+\page
+
+For example, the output with \options{width=1.5bp, angle=45} is:
+
+{\setupvisualcounter[dummy][width=1.5bp, angle=45]\showcounter[4]}
+
+\blank[2*big]
+
+An angle less than \options{0} changes the direction of the stroke.
+For example the output with \options{width=1.5bp, angle=-45} is:
+
+{\setupvisualcounter[dummy][width=1.5bp, angle=-45]\showcounter[4]}
+
+
+\visualsection {The \command{mayanumbers} counter}
+
+The \command{mayanumbers} counter is inspired by the Mayan numbering system that I saw in the
+documentary \quotation{Breaking the Maya code}. It counter does not strictly
+follow the Mayan numbering system. The Mayan numbering system is written
+vertically; the output of this counter is horizontal which makes it more useful
+for displaying page numbers in presentations.
+
+\definevisualcounter
+ [dummy]
+ [mayanumbers]
+
+\showcounter[2*2]
+
+\blank[2*big]
+
+The shape of the small and the large markers is as follows:
+
+\startmiddlealigned
+ \startcombination[2]
+ {\usevisualcounter[n=1,last=5,width=3EmWidth, height=3ExHeight]{dummy}}
+ {The shape of the small marker}
+ {\usevisualcounter[n=5,last=5,width=3EmWidth, height=3ExHeight]{dummy}}
+ {The shape of the large marker}
+ \stopcombination
+\stopmiddlealigned
+
+\page
+
+The \command{scratchmarks} counter has the following tunable parameters:
+\startitemize[packed, joinedup]
+ \item \options{width} (default value \options{1EmWidth}): The width of the
+ small marker.
+ \item \options{height} (default value \options{1ExHeight}): The height of the
+ markers.
+ \item \options{distance} (default value \options{width/4}): The distance
+ between two small markers. The distance between each group of four small
+ counters is \command{2*distance}.
+\stopitemize
+
+\blank[2*big]
+
+For example, to get an output that is half the default size, use
+the options \goodbreak \options{width=0.5EmWidth, height=0.5ExHeight}.
+
+{\setupvisualcounter[dummy][width=0.5EmWidth, height=0.5ExHeight]\showcounter[4]}
+
+% {\setupvisualcounter[dummy][style=\tfxx]\showcounter[4]}
+
+\visualsection {The \command{countdown} counter}
+
+This counter is inspired by the spinning wheel on the iPhone and on Google
+images.
+
+\definevisualcounter
+ [dummy]
+ [countdown]
+
+\startmiddlealigned
+ \startcombination[4]
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=3, last=12]{dummy}}}{3 out of 12}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=4, last=12]{dummy}}}{4 out of 12}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=5, last=12]{dummy}}}{5 out of 12}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=6, last=12]{dummy}}}{6 out of 12}
+ \stopcombination
+\stopmiddlealigned
+
+\blank[2*big]
+
+The \command{countdown} counter may also be used with a text display of the
+counter.
+
+\startmiddlealigned
+ \startcombination[4]
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=3, text=3, last=12]{dummy}}}{3 out of 12}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=4, text=4, last=12]{dummy}}}{4 out of 12}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=5, text=5, last=12]{dummy}}}{5 out of 12}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=6, text=6, last=12]{dummy}}}{6 out of 12}
+ \stopcombination
+\stopmiddlealigned
+
+\blank[2*big]
+
+The example below shows how the counter changes when the number of steps are
+increased.
+
+\startmiddlealigned
+ \startcombination[4]
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=13, last=24]{dummy}}}{13 out of 24}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=14, last=36]{dummy}}}{14 out of 36}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=25, last=48]{dummy}}}{25 out of 48}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=36, last=60]{dummy}}}{36 out of 60}
+ \stopcombination
+\stopmiddlealigned
+
+\page
+
+The \command{countdown} counter has the following tunable parameters:
+\startitemize[packed, joinedup]
+ \item \options{width} (default value \options{1EmWidth}) and \options{height}
+ (default value \options{1ExHeight}): The maximum of these two determine the
+ difference between the inner and outer diameter of the ring.
+
+ \item \options{text} (not set by default): The text to be displayed in the
+ middle of the counter.
+
+ \item \options{maxtext} (not set by default): The diameter of the inner circle
+ is equal to \options{1.5} times the maximum of the width and the height of
+ \options{maxtext}.
+
+ \item \options{distance} (default value \options{3EmWidth}):
+ The distance between the consecutive markers along the circumference of the
+ outer circle is equal to \options{distance/last}.
+\stopitemize
+
+\blank[2*big]
+
+For example, to get a continuous circle set \options{distance=0pt}:
+
+\startmiddlealigned
+ \setupvisualcounter[dummy][distance=0cm]
+ \startcombination[4]
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=13, last=24]{dummy}}}{13 out of 24}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=14, last=36]{dummy}}}{14 out of 36}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=25, last=48]{dummy}}}{25 out of 48}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=36, last=60]{dummy}}}{36 out of 60}
+ \stopcombination
+\stopmiddlealigned
+
+When the high level interface is used, i.e., when the option
+\options{counter=...} is set, the value of \options{text} is the converted value of the
+counter, and the value of \options{maxtext} is the converted value of last
+counter.
+
+\visualsection {The \command{markers} counter}
+
+The \command{markers} counter is inspired by the section markers displayed by
+the \LATEX{} \options{beamer} package. This module comes in two shapes: the
+default shape is circle
+
+\definevisualcounter
+ [dummy]
+ [markers]
+
+\showcounter[1*4]
+
+\page
+
+The alternative shape is a square, which is selected using
+
+\starttyping
+ \setupvisualcounter
+ [...] % [[\comment{name of the counter}]]
+ [
+ ...
+ mpsetups=[[\options{visualcounter::markers:square}]],
+ ...
+ ]
+\stoptyping
+
+{\setupvisualcounter[dummy][mpsetups=visualcounter::markers:square]\showcounter[1*4]}
+
+\page
+
+The \options{visualcounter::markers:square} is a predefined alternative shape.
+Before discussing how to define a new shape, lets look at the tunable parameters
+of the \command{markers} counter:
+\startitemize[packed, joinedup]
+ \item \options{width} (default value \options{1EmWidth}): The width of the
+ each marker.
+
+ \item \options{distance} (default value \options{width/4}): The edge to edge
+ distance between successive markers.
+
+ \item \options{mpsetups} (default value \options{visualcounter::markers:circle}):
+ A \command{useMPgraphic} that determines the shape and the display of the
+ markers. The module comes with three predefined shapes,
+ \options{visualcounter::markers:circle}, \goodbreak
+ \options{visualcounter::markers:square}, and
+ \options{visualcounter::markers:star}.
+\stopitemize
+
+To define a new shape, you have to create a \command{useMPgraphic} that defines
+three \METAPOST{} macros:
+
+\startitemize[packed, joinedup]
+ \item \options{show_past_marker(expr shift)}
+ \item \options{show_active_marker(expr shift)}
+ \item \options{show_future_marker(expr shift)}
+\stopitemize
+
+The argument to these macros is the shift calculated based on their position.
+The macros are responsible for using the shift amount either for horizontal
+shift or for vertical shift, and coloring the markers with appropriate colors.
+The three colors from the color palette are available as \options{past_color},
+\options{active_color}, \options{future_color}.
+

+As an example, lets consider a new visual counter that displays a
+\quotation{star rating}:
+
+\startmiddlealigned
+ \startcombination[3]
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=1]{stars}}}{1 out of 5}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=3]{stars}}}{3 out of 5}
+ {\framed[frame=off,width=0.2\textwidth]{\usevisualcounter[n=5]{stars}}}{5 out of 5}
+ \stopcombination
+\stopmiddlealigned
+
+For better visual effect, I have also changed the color palette to one that uses
+same color for \options{past} and \options{current} markers. Note
+that the above alternative is available as the
+\options{visualcounter::markers:star} option to \options{mpsetups}. The following
+description is just to explain how to define a new marker.
+
+\page
+
+To create such a counter, first create a \command{useMPgraphic} as follows (I
+could have used any name instead of \options{visualcounter::markers:star}):
+
+\adaptlayout[lines=+2]
+
+\typebuffer[star-definition]
+
+\page
+
+Next, define a new \command{visaulcounter} that inherits from \command{markers}
+but uses a different \options{mpsetups}:
+
+\typebuffer[star-counter]
+
+\startbuffer[star-example]
+\usevisualcounter[n=4]{stars}
+\stopbuffer
+
+To use this counter, type:
+
+\typebuffer[star-example]
+
+which gives: \framed[frame=off,location=lohi]{\getbuffer[star-example]}
+
+
+
+\visualsection {The \command{progressbar} counter}
+
+The \command{progressbar} counter is based on a question on TeX.SE. This counter
+is not yet finalized. I am still working on the interface to change the shape of
+the progress bar, and perhaps add some shading.
+
+\definevisualcounter
+ [dummy]
+ [progressbar]
+
+\showcounter[1*4]
+
+
+\visualsection {The \command{pulseline} counter}
+
+The \command{pulseline} counter is based on the heart pulses shown in a heart
+rate measurement device. This counter is not yet finalized.
+
+\definevisualcounter
+ [dummy]
+ [pulseline]
+
+\definepalet
+ [green]

+
+% \section[sec:new-counters]{How to define new counters}
+%
+% The name of the \command{useMPgraphic} must start with \options{visualcounter::}
+% (note the double \options{::}), so that the graphic uses the
+% \options{visualcounter} MP instance.
