arrowhead and transparency


Recommended Posts

Hello

Is there a way to combine the line and arrowheads, so that when transparent the overlay is not shown?

Group the curve (with or without arrowheads already added) before you apply transparency.

thank you.

Is this a workaround or is this the way to go?
I think it is a little weird to group a single curve.

I can think of 3 other ways, but they are all work-arounds which are a bit clunky…

1. Expand stroke, Boolean add to merge the 3 pieces, then use any method of obtaining transparency.
:( No longer a path with a stroke, but a shape, so much harder to edit.

2. Add a curves adjustment and set the max value of the alpha channel to 50%

3. Use a pixel mask filled with 50% Grey

Personally I'd use Alfred's method and just group the line!

Besides this transparency issue I also notice another unexpected occurrence with arrow heads:

They appear to make the "Align" buttons in Stroke panel not reacting but automatically set the stroke align to centeredregardless of the align setting before applying arrow heads.

The problem of arrowhead and transparency is an interesting observation, and as I think about it, I'm not sure what to suggest. If it is desirable to be able to set a different color for the arrowheads, then I see this as a necessary consequence, as alpha is a part of the color definition, and perhaps occasionally you would even want this behavior.

Therefore, I think there needs to be some way to keep this behavior when it is desired, but also an easy way to assign a color to the entire curve rather than individually as a default. Maybe a couple of options:

1. By default set the stroke color to the entire curve as a single value, with the option to set arrowhead color differently.

2. Or keep separate definitions but offer a checkbox to clip the overlaps.

Maybe there is a better solution than these from a UX standpoint.
