Hi all!

I'm working to my first presentation. But I have some difficulties at making
backgrounds:

1. how can I use in metapost an external image? (e.g a png)
2. how can I set the text color to white (all text in the presentation)

given that you have the latest context, how about: 

externalfigure "somebitmap.png"
  scaled 2
  shifted (10,100)
  rotated (-45) ;

>2. how can I set the text color to white (all text in the presentation)

let's reveal another new secret key: foregroundcolor 

\starttext

\setupcolors[state=start]

\setupbackgrounds
  [page]
  [background=color,backgroundcolor=red,
   foregroundcolor=white]

\input tufte

\stoptext

Simple eh?

3. How can I clip a text scaled and shifted? For example, I want to
intersect a logo text with a circle, so that the part outside the circle
remains black, and the part inside the circle remains white?

Simple, indeed but it did not worked. The text on the slides remained black.
I tried:
\setupbackground[page][background={color,Sintezis},backgroundcolor=blue,
foregroundcolor=white]

but, as I said, the text on the slides is still black.

there is an example of clipping in the mp manual, 

(1) define a clip path in mp (keep an eye on the refernce point) 
(2) hook it into the clip routine

Hello!

I have the latest beta from pragma-ade. But when I tried, it did not worked!
Neither the external figure, nore the textcolor. I send you the presentation
style, maybe there is a solution.

What about the 3rd question? (scaling and clipping text?)

%D \macros
%D   {setuplayout}
%D
%D The layout is rather symmetrical. We don't use headers and

%D \macros
%D   {TitlePage, Topics, Topic}
%D
%D A presentation normally consists of a title page, a list of
%D topics, and the content itself. In this style, a further
%D subdivision does not make sense, but because we want to be
%D compatible with the other styles, they are added. A
%D presentation looks like:
%D
%D \starttypen
%D \usemodule[pre-antikwa]
%D
%D \startext
%D
%D \TitlePage{The Title}
%D
%D \Topics{Contents}

%D
%D ...
%D
%D \stoptext
%D \stoptypen

%D \macros
%D   {definehead, Topic, Subject}
%D
%D We use dedicated sectioning commands.

\definehead [Topic]   [chapter]
\definehead [Subject] [section]

\definehead [Nopic]   [title]

%D \macros
%D   {setuphead}
%D
%D We turn of numbering. The assignment to \type {after} takes
%D care of the increasing indentation. This indentation is the
%D only low level \TEX\ code needed. Including this
%D functionality in the core of \CONTEXT\ is not that useful
%D and I would forget about this feature being present anyway.

\setuphead
  [Topic, Nopic, Subject]
  [number=no,
   after={\blank[2*big]\ToTheLeft\everypar{\ToTheRight}}]

%D After section titles we set the \type {\leftskip} to a value
%D that suits the Antikwa slant.

\def\ToTheLeft%
  {\gdef\LeftSkip{30}%
   \rightskip0pt\relax
   \leftskip30pt\relax}

%D Each new paragraph adds to the \type {\leftskip}.

\def\ToTheRight%
  {\doglobal\increment(\LeftSkip,20)%
   \leftskip=\LeftSkip pt\relax}

%D \macros
%D   {Topics}
%D
%D The \type {\Topics} command uses a bot of low level
%D \CONTEXT. We could have done with:
%D
%D \starttypen
%D \def\Topics#1%
%D   {\Nopic[Topics]{#1}
%D    \placelist[Topic][criterium=all]}
%D \stoptypen
%D
%D but the next alternative sort of ignores this command when
%D no list is found.

\def\Topics#1%
  {\determinelistcharacteristics[Topic]
   \ifcase\utilitylistlength\else
     \Nopic[Topics]{#1}
     \placelist[Topic][criterium=all]
   \fi}

%D \macros
%D   {setuplist}
%D
%D We use the single item command to achieve a result similar
%D to the itemizations.

\setuplist
  [Topic]
  [alternative=command,
   command=\TopicListCommand]

\def\TopicListCommand#1#2#3%
  {\item#2\par}

%D A dummy command, needed to be compatible with the other
%D presentation styles.

\def\Subjects%
  {}

%D \macros
%D   {StartTitlePage}
%D
%D We use a nested \type {\everypar}; everything in there
%D will be put in front of each paragraph. The nesting prevents
%D the first paragraph from indenting. The struts give the 
%D lines a decent height, which looks better inrelation to the
%D next pages. 

\def\StartTitlePage%
  {\startstandardmakeup
   \bfd\setupinterlinespace
   \everypar{\everypar{\advance\leftskip30pt\relax}}
   \let\\=\blank
   \begstrut}

\def\StopTitlePage%
  {\endstrut

beware: mp-tool is already included automatically, so doing it twice makes
no sense   

do you use metafun, if so, have you regenerated the metafun format 

don't call your files s-*.tex just name them 

\startenvironment mine 

\stopenvironment 

and include them with 

\environment 

that way they will not clash with future modules in the distribution

Hi Dan,  

you can use 

\setupbackgrounds[text][foregroundcolor=white,background=fake]

as a hack for your urgent needs 

[indeed there is an additional layer for text]

ok, I will change it.

How do I regenerate the metafun format? Indeed, sometimes it complains with
it.

the mem file will end up on your local path (so you have to move it to
web2c) unless you have set the MPMEMS env var.
