Link corners (2 issues) (Read 828 times)

	Hello, while working with the links we discovered several problems, namely: 1. Link corners stop being rounded if radius values are greater than 10 (see Attachment 1) 2. The actual radii of the corners are different if the corners are close to each other (see Attachment 2)

	Hi, 1. It seems we have some max constraint left from Windows Forms version of the control where we use millimeter units, and so value is too small for WPF's points. Our developer will adjust it or remove altogether. 2. That is by design as we want to always show a part of the segment between two corners as straight line. We'll add some flag to let you disable that. We'll try to publish these as patch on nuget in next few days. Regards, Slavcho Mindfusion

	Hi, Try this build to remove the max radius constraint - https://www.nuget.org/packages/MindFusion.Diagramming.Wpf/4.3.0-alpha2 and for time being set this flag until we decide on an official property: Code DevFlags.RoundedLinksAvoidUturns = false; Regards, Slavcho Mindfusion

	Hi, Have you enabled the 'include prerelease' option to install alpha2 package? If you were using locally installed assemblies before installing from nuget, try also deleting them from project explorer window, in case local assemblies have higher priority. Regards, Slavcho Mindfusion

	Hi, I tried setting the flag DevFlags.RoundedLinksAvoidUturns = false; But unfortunately this did not help.

	Hi, Links have a separate drawing path when LinkCrossings is enabled, and it seems we've missed it. For time being you should be able to see the expected geometry by keeping only RoundedLinks enabled, but LinkCrossings disabled (= Straight). Our developer will fix the LinkCrossings case later this week. Regards, Slavcho Mindfusion

	Hi, RoundedLinksAvoidUturns should work with LinkCrossings enabled too in this build - https://www.nuget.org/packages/MindFusion.Diagramming.Wpf/4.4.0-beta1 Regards, Slavcho MindFusion Code DevFlags.RoundedLinksAvoidUturns = false; Code DevFlags.RoundedLinksAvoidUturns = true;

	Hi team, we’ve run into another issue. The corner rounding changes when the selection is cleared. Version: 4.4.0-beta3 DevFlags.RoundedLinksAvoidUturns = false; (I have attached a video to the message; please take a look.)

	Hi Andrey, I cannot find dependencies on Selected value in rounded links drawing code. Please check if there are any (possibly experimental) assignments to RoundedLinkRadius or RoundedLinksAvoidUturns in your diagram's click or selection related event handlers. In video it also seems there's some custom drawing involved, I think those aren't diagram's default selection handles. If problem is not from property assignments, please post your custom-draw events code. Regards, Slavcho Mindfusion
