[Therion] Label and passage height colours

[Bruce Mutton]

I’m sorry Paul, I’m still inside a Covid cloud it seems.  

-context works with symbol-show and symbol-hide but not with symbol-colour, so it is not a solution to your problem.

Hi Bruce,

Yes, I was wanting to change a specific instance. These are great tips. 

 

Using the colour of another point type that I'm not using, then changing the context for other specific points, would be a simple hack that I think would cover me.

 

Cheers,

Paul

Hi Paul

If you are asking if it is possible to change the colour of a specific instance of a particular type of generic object, I think the answer is no, unless you modify the metapost definition for the generic object to allow attributes such as colours to be parsed. 

If you want all of a generic object type to be a colour, then use a layout statement something like:

symbol-colour point label <colour>

 

Easy hacks to mimic the first question include…

Use point remark and set its colour to something striking with:

symbol-colour point remark <colour>

You can change the fonts to add or remove emphasis.

 

Or use -context to make the label inherit colour as though it were another type of symbol…

              point label <x> <y> -text “label text” -context point anastomosis

and

              symbol-colour point anastomosis <colour>

I suspect not all point types work with -context, so you may have to hunt around to find one that works.

Is it possible to change the label and/or passage height colours for specific points? I couldn't see a way of doing this.

 

Thanks,

Paul Rowe
