LineDash cannot handle complex patterns

[manutiedra]

There wasn't anything I couldn't do in VectSharp until I found dashed lines with complex patterns like most of:

Unfortunately, the current implementation of LineDash only lets you specify one "on" and one "off" length. However, SVG lets you specify an array that lets you handle the most complex patterns:

Is there any plan to improve the LineDash to support this?

Hi! I'm glad VectSharp has been useful to you!

Thank you for pointing this out! The reason I implemented LineDash like that is that I though the PDF specification only supports one "on" and one "off" length, but I just realised that this is not the case - it's just that all the examples in the spec document are like that 😅

I will work on the implementation, let's leave this open in the meantime!

This is now implemented in VectSharp 2.6.0! The LineDash constructor now has additional overloads that accept a dash array parameter, which can be used to specify complex dash patterns like the ones above. This is also briefly mentioned in the docs.

You can even animate the dash patterns!

I'm closing this issue for now, feel free to reopen it (or create a new one) if you see any problems with this or if you have any other question!

Outstanding work man! Thank you very much
