Re: [Guidolib-devel] Controlling system render height

[Arshia C. <ars...@an...>]

Hello Dominique et al.

So in order to create an artificial rendered dynamic zoom, I believe we should be playing around with StaffFormat’s Size parameter (3pt by default), combined with API’s Spring parameter to introduce more space between events. I believe it’s doable.

For the StaffFormat, I can see three ways of doing it. I’m wondering which one you’d recommend me to go for:

(1) Modify the GMN source (such as in GuidoAR). Not ideal since it’d reduce dynamicity of the library and not elegant! :)
(2) Modify the AR attributes of all staves, and re-render
(3) Directly modify parameters in the GR domain, such as staffLSPACE (or similar) after a thorough study of dependencies, and re-render

Let me know which way you’d pick and I’ll go through the necessary learning curve.

This can be achieved somehow if we can control the Height of the system on a page. Playing around with the engine, I don’t seem to be able to control this parameter. Ideally you’d want to control a default staff height where the system would infer from that given a score… .
