Create Highlight type of Line

[rmcmanamy]

The highlight text uses a true highlight where yellow is pure yellow and all objects below it show through even with the Opacity set to 100%. Black still shows through as black so I'm guessing it's using a multiply transparency.

Lines and other objects though look to use No transparency along with the Opacity value. So yellow at 80% Opacity over black shows the black as gray now.

Is there anyway to set the transparency on lines and stuff also or would we have to look at using JavaScript to modify the annotations afterwards?

Is this something that can be added into the next release as it would be very helpful to say the least.

Hi Rodney,

Using the Ax methods you can change commenting tools styles (before adding an annotation to a PDF), but if you want to change existing annotations within a PDF document you should use JS for this.

Thanks but there is nothing that I see for changing the transparency type (Blend Mode)for the AX methods. I thought maybe we could pass an RGBA value instead of RGB for the FColor and SColor but that doesn't seam to do it either. I'm also not 100% sure if the line comments even allow this but from the spec it looks like one could add a it to the Appearance Dictionary.

In looking at the difference between the highlight and the line the Highlight does have a Multiply ExtState in the Appearance Dictionary where the line doesn't. So I would think Adobe would recognize it if it was in there for the line object also.

Well, you can change the "Opacity" property for commenting tools styles - that’s all for now.

It would be great if they could allow one in the short term to say maybe pass in a negative RGB value or something to enable the Multiple Blend Mode to be used on all annotation objects besides just the Highlight one.

I realize that Adobe doesn't have his in their dialogs either but it would be very helpful for us to be able to use a true highlight color with Multiply Blend Mode like the Highlight Text Tool does .

Thanks again.
