Re: [Guidolib-devel] Generate Measure Number at the beginning of Page/line?

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

Dominique,

I see this on iOS. See the attached Screenshot (which is very basic Guido Render from XML). I use the “grParameters.layoutSettings.systemsDistribution = kNeverDistrib” to get 1 system per page.

Note that we start to see measure numbers on the fifth page only because the first letter is out-of-page here.

In case it helps, here are the grParameters that we pass to AR2GR:

	grParameters.layoutSettings.spring = 1.1f;
	grParameters.layoutSettings.force = 750;
	grParameters.layoutSettings.systemsDistribution = kNeverDistrib; // Important to get 1 system per page
	grParameters.layoutSettings.systemsDistance = 10000; // Important to get 1 system per page
	grParameters.layoutSettings.neighborhoodSpacing = 0;
	grParameters.layoutSettings.optimalPageFill = 1;
	grParameters.layoutSettings.resizePage2Music = 1;
	
	grParameters.pageFormat.width = GuidoInches2Unit(MAX(width, 370) / 72.0); // ≥370px to avoid re-layout when the force-spring algorithm can't cope with high-density areas (making one long page)
	grParameters.pageFormat.height = 0;
	grParameters.pageFormat.marginbottom = 0;
	grParameters.pageFormat.margintop = GuidoInches2Unit((15) / 72.0);
	grParameters.pageFormat.marginleft = GuidoInches2Unit(0 / 72.0);
	grParameters.pageFormat.marginright = 0;
