All arrow and box lines drawn with incorrect width after a Windows Update (Read 10880 times)

	After the following Windows updates in seems that any arrow lines and box borders without a specified width are drawn with the wrong width. Even the border around the +/- buttons is affected. KB890830 - Malicious software removal tool (probably not the culprit!) and KB5006670 - Cumulative update for Windows 10 21H1 x64 Systems The software has not changed in any way - I just did the update. See the attached file to see what has happened. DavidL

	Indeed, it happens on our end too. Apparently GDI's so called cosmetic pens (with zero width) no longer work. Before KB5006670 they used to draw 1-pixel wide lines regardless of graphics unit and zoom level. For time being you could set some global style properties as below to fix border lines (and will have to update them after zoom level changes if you don't want zooming to scale line widths). For other graphics elements you might have to set properties on individual items. diagram.ShapeNodeStyle.StrokeThickness = 0.1; diagram.DiagramLinkStyle.StrokeThickness = 0.1; Regards, Slavcho Mindfusion

	Many thanks. I also had to add flowChart.DiagramLinkStyle.HeadStrokeThickness = 0.1; and do the following to fix up older files after reading (NOTE: BlackPen has a thickness of 0.1f) foreach (var node in flowChart.Nodes) node.Pen = BlackPen; foreach (var link in flowChart.Links) { link.Pen = BlackPen; link.HeadPen = BlackPen; } The next thing that I can't seem to fix is the blocky +/- buttons. Do you have a fix for that?

	The only way I can find in source code is overriding DrawManipulators, in case you are using a custom node type. We'll be releasing a fix for this next week anyway. Regards, Slavcho

	I look forward to the new release. Two questions... Will the new release fix all the problems or will we still need to add all the lines of code previously referred to? Our subscription ran out in 2016. I assume that we will need to purchase a new one. DavidL

	We have implemented our own zero-width pens support here - https://mindfusion.eu/_beta/fcnet68.zip You shouldn't need to use the global styles workaround with that. We won't be able to patch versions from 2016, but if you have license with source code we could send you the diffs to merge. Regards, Slavcho

	We have a licence without source code so a renewal of the licence would be required. I will try out the attached version to see if it works OK DavidL

	Software checks out OK. Look forward to release next week. Did find one glitch, though - a downward facing arrow with a thick border. DavidL

	We might have missed adjusting some System.Pen constructor call. We could not reproduce that with built-in Arrow3 shape though. Could you post the code you use to initialize that arrow?

	Nevermind, we were testing with ShapeOrientation, but now found some RotationAngle values lead to that.

	I also had this problem. I fixed most things but can't work out how to get the arrows of a link to touch the line/outline of the shape it connects to rather then overlap the line (as attached). Any assistance on how to fix this most welcome.

	Slavcho, can you let me know which parameter sets the width of the line for the selection box (as attached). It has gone thick as well.

	...found it. Diagram.Selection.Pen.Width ....determines the width of the selection box/rectangle.
