Hello ConTeXters, is there a way how to get laundry symbols into ConTeXt? - The image is copied from "The Comprehensive LATEX Symbol List", Scott Pakin. TIA. Best regards, Lukas -- Ing.

The proper way would be to use ConTeXts symbol mechanism. I guess the symbols can then be accessed my name. However, I didn't find the laundry symbol names in any MkIV file in the distribution. It seems that nobody maintained an up-to-date list. You can always access the characters directly: \getglyph{marvosym}{\char 247} To find out which symbols are at which slot, use \showfont [marvosym] Marco

To find out which symbols are at which slot, use

\showfont [marvosym]

It’s easier to create a list with all symbols and their names. \usesymbols[mvs] \starttext \showsymbolset[martinvogel 2] \stoptext Wolfgang

... Thanks both for your answers. My code so far is: ---- \usesymbols[mvs] \starttext \startcolumns[n=2,rule=on] \showsymbolset[martinvogel 2] \stopcolumns \page \startcolumns[n=4,rule=on] \dorecurse{1024}{\recurselevel --\getglyph{marvosym}{\char\recurselevel\par}} \stopcolumns \stoptext ---- And how to access symbols by their names, e.g. how to use symbol named "AtForty"? - The symbol list shows only symbolic names, not values (to be used with Marco's \char <value>). \AtForty gives error, so is it to be used with \usesymbol or \symbol or something like that?

- The symbol list shows only symbolic names, not values (to be used with Marco's \char <value>).

\AtForty gives error, so is it to be used with \usesymbol or \symbol or something like that?

\usesymbols[mvs] \starttext \symbol[martinvogel 2][ShortForty] \stoptext or \usesymbols[mvs] \setupsymbolset[martinvogel 2] \starttext \symbol[ShortForty] \stoptext Wolfgang

- How to scale the desired symbol, e.g. 5 times? I played with "scale" somehow, but no effect. - Where the symbol set name "martinvogel 2" comes from? Is it a name "built in" the font file? - - Is "2" part of the name or does it mean something, e.g. a factor? Thanks again. Best regards, Lukas -- Ing.

It scales with the current font size. \usesymbols[mvs] \setupsymbolset[martinvogel 2] \starttext \symbol[ShortForty] {\tfd\symbol[ShortForty]} \stoptext

The symbols are defined in symb-imp-mvs.mkiv, with \usesymbols[…] you load the file.

The symbols are just put in named groups and “martinvogel 2” is the name of one of these groups (there is also “martinvogel 1”, don’t know how created these names). When you define a symbol you can set the name as \definesymbol[<name>]{<symbol>} or out it in a category with \definesymbol[<category>][<name>]{<symbol>} When you have many symbols which you want to put in a category you can say \startsymbolset [<category>] \definesymbol[]{} \definesymbol[]{} \stopsymbolset and omit the first argument. To print a symbol from this symbolset you have to write \symbol[<category>][<name>] but when you add \setupsymbolset[<category>] to your document ConTeXt will search in this symbol set even when you write only \symbol[<name>] Wolfgang

When you define a symbol you can set the name as

\definesymbol[<name>]{<symbol>}

or out it in a category with

\definesymbol[<category>][<name>]{<symbol>}

When you have many symbols which you want to put in a category you can say

\startsymbolset [<category>]

\definesymbol[]{} \definesymbol[]{}

\stopsymbolset

and omit the first argument. To print a symbol from this symbolset you have to write

\symbol[<category>][<name>]

but when you add

\setupsymbolset[<category>]

to your document ConTeXt will search in this symbol set even when you write only

I'm trying to use ConTeXt with Metafun to produce a map of a videogame I am working on. In fact I did it 9 years ago but it seems that now it doesn't work. I have two 32 pixels wide by 40 pixels high sprites. They are saved in the skysprite.png and sandsprite.png files. Since 32 = 4 x 8 and 40 = 5 x 8, the width/height ratio is 4/5. This should produce a page with a sky sprite and a sand sprite, one below the other. It worked in the past. Each sprite should be 4 x 0.095 cm = 0,38 cm wide and 5 x 0.095 cm = 0.475 cm high: \starttext \setupMPinstance[metafun][textstyle={\switchtobodyfont[termes,8pt]}] \startuseMPgraphic{mapa} u:=.095cm; draw externalfigure "./skysprite.png" xscaled 4u yscaled 5u shifted (0u,-0u); draw externalfigure "./sandsprite.png" xscaled 4u yscaled 5u shifted (0u,-5u); \stopuseMPgraphic \useMPgraphic{mapa} \stoptext But instead I got two huge sprites of 2.8 cm x 4.4 cm. Am I forgetting something? Thanks

But instead I got two huge sprites of 2.8 cm x 4.4 cm.

Am I forgetting something? Originally that worked because the image was always 'included' at 1 bp and then scaled but that was (1) inaccurate and (2) a bit depending on

Great! Thanks Hans, now it works. I replaced the "draw externalfigure" commands by draw externalfigure "./skysprite.png" xsized 4u ysized 5u shifted (0u,-0u); draw externalfigure "./sandsprite.png" xsized 4u ysized 5u shifted (0u,-5u); Best regards On Sun, Jan 2, 2022 at 3:36 PM Hans Hagen wrote:
