Now, I tried with overlays and layers. That's fine. In any case, in a
second approach I simply used \setlayer to fill repeatedly the same
layer. The result seems to be the same.
What's the difference? Is it safe to use the second approach?
Then: changing layer dimension in \definelayer, I cannot see any
differences in the output.
Can anyone explain what it should happen?
Thanks

-a-
Two examples follow:
\setupcolors[state=start]
% first approach
\definelayer [layer1][]
\definelayer [layer2][]
\definelayer [layer3][]
\setlayer [layer1]
[x=.5\paperwidth, y=.5\paperheight]
{\externalfigure[layTest][]}
\setlayer [layer2]
[x=.35\paperwidth, y=.45\paperheight]
{\externalfigure[layTest][]}
\setlayer [layer3]
[x=.5\paperwidth, y=.5\paperheight]
{\color[darkred]{ \bf This is a text}}
\defineoverlay[overlay1][{\placelayer[layer1]}]
\defineoverlay[overlay2][{\placelayer[layer2]}]
\defineoverlay[overlay3][{\placelayer[layer3]}]
% end of first
% second approach
\definelayer [layer1b][] % just one
\setlayer [layer1b]
[x=.5\paperwidth, y=.5\paperheight]
{\externalfigure[layTest][]}
\setlayer [layer1b]
[x=.35\paperwidth, y=.45\paperheight]
{\externalfigure[layTest][]}
\setlayer [layer1b]
[x=.5\paperwidth, y=.5\paperheight]
{\color[darkred]{ \bf This is a text}}
% end
\starttext
% using first
\framed [height=\textheight,width=\textwidth,background={overlay1,
overlay2, overlay3},align=right, frame=off]
{
% write if you need to
}
% using second
\framed
[height=\textheight,width=\textwidth,background=layer1b,align=right,
frame=off]
{
% write if you need to
}
\stoptext
