Dear list,

the attached .tex file is the minimal working example we discussed today in the online meeting.

I realized that the approach of looping through k of p[k] is not fitting my needs, because it's not flexible enough.

I need another approach, one which works with layer sets.

I would stop using p as an array, because with the layer sets approach we don't have a fixed order of the layers.

So the definition of the layers would be something like

    picture layerA;

    layerA:=image(

    label("Word 1", z1);

    );

    picture layerW;

    layerW:=image(

    label("Mot 2", z2);

    );

    picture layerM;

    layerM:=image(

    label("Parola 3", z3);

    );

   

    picture layerC;

    layerC:=image(

    label("Wort 4", z3+z1);

    );

    picture layerY;

    layerY:=image(

    label("Nummer 5", z2+z3);

    );

   

    picture layerU;

    layerU:=image(

    label("number 6", z2+z1);

    );

After that, I would define layer sets and layer subsets. This will be done manually for each layer set and each layer subset.

I don't know the proper syntax to do that. Let's assume we could use a variable type called "myset".

myset layersubsetGamma;

layersubsetGamma:={layerU,layerM};

In my logic, the layers will be drawn in the order of their appearance within the {}. In the example, drawn content of layerM might cover drawn content of layerU.

Contrary to a layer subset, each layer set will result in a PDF page, and thus the layer sets are related to each other by an inner order. That's why I would use an array variable here with [].

I don't know how to append a set. In the following example, I assumed there would be a function myappend(<initial set>, <the things what the initial set should be appended with>)

myset layerset[];

layerset1 := {layerW,layerA};

layerset2 := myappend{layerset1, layerY};

layerset3 := myappend{layerset2, layersubsetGamma};

layerset4 := myappend{layerset2, layerU};

layerset5 := myappend{layerset4, layersubsetGamma};

Finally, I would need each layerset[k] typeset on its own pdf page. And of course on each page k, only the layers which appear in the definition of the layerset[k] should be drawn on top of each other in the order as they appear in that definition.

I'm very curious to hear your suggestions.

Thanks

Emanuel
