new font trickery

[Hans Hagen]

Hi Jairo,

(to the list for those who want to play with it)

In addition to the metapost fotn subsystem I also made a tex variant. 
That one is currently based on setups. So, we now can use mp as well as 
tex to make fonts. Of course this is mostly for special purposes and for 
fun but both are quite efficient.

\starttext

\setupexternalfigure[directory={global,default}]

\startsetups box:demo:103
     \externalfigure[cow-brown.pdf][height=12pt]
\stopsetups

\startsetups box:demo:104
     \externalfigure[cow-black.pdf][height=10pt]
\stopsetups

\startsetups box:demo:105
     \externalfigure[mill.png][height=12pt]
\stopsetups

\startsetups box:demo:106
     \externalfigure[hacker.jpg][height=12pt]
\stopsetups

\registerboxglyph category {demo} unicode 103 \relax % rather low level 
for now
\registerboxglyph category {demo} unicode 104 \relax % rather low level 
for now
\registerboxglyph category {demo} unicode 105 \relax % rather low level 
for now
\registerboxglyph category {demo} unicode 106 \relax % rather low level 
for now

\definefontfeature[whatever][box=demo]

\definedfont[Serif*whatever]

% \enabletrackers[fonts.collecting]

\startTEXpage%[offset=0pt]
    %\hbox{g}%
     \hbox{\char103}%
     \hbox{\char104}%
\stopTEXpage

\startsetups box:demo:whatever
     \startMPcode
         picture p ; p := image (draw figure "hacker.jpg" ysized 10pt);
         fill      boundingbox p enlarged .5pt randomized 2pt withcolor 
"darkgray" ;
         clip p to boundingbox p enlarged -1pt randomized 2pt ;
         draw p ;
     \stopMPcode
\stopsetups

Sorry, Hans, but I’m afraid it doesn’t work for me.

To find images, I neeed to add:

  \setupexternalfigure[location={default}]

I only get black cows and black squares for bitmap images.

I think this isn’t intended.

Many thanks for your help,

Pablo

Many thanks for your reply, Hans.

Images are found, but not with "directory=default", but with
"location=default".

Evince doesn’t display the images or colors. Acrobat for Linux doesn’t
display it either (this is why I thought it might be a bug).

But MuPDF and SumtraPDF (based on MuPDF) display it fine.

Sorry for the noise and many thanks for your help,

Pablo

An (in the meantime probably old version of) okular (windows) also shows 
it ok ... time to ditch (or update) evince I guess.
