semi transparent drawing over the picture

[Nagaa]

Hello every one

I am drawing the arrow image over the picture , so after drawing the arrow over the picture how to make it semi transparent so that background picture also should appear . 

 Please see the attached vi

One option to consider is to place a transparent window on top of your existing picture.

Then draw on the transparent window.

I think you have'nt seen my vi in arrow.1zip file. Please see it

I want semi transparent drawing over the 2d picture at run time . Not when programming

Any chance you might have a go at attempting the solution yourself..?

If you make the 2d picture and transparent drawing into a custom control, you can use the visible property node to make it visible and invisible during runtime.

Yes I understand what you're trying to do...

I don't understand what's stopping you from doing it yourself...

This will be my last post on the thread until you make some effort yourself

ok strokes 

Previously also i tried with function Draw grayed out rectangle.vi 

This function is supporting only for the shape rectangle . I want this kind of same function for irregular shapes also .

Generally, I would like to use image annotating control to draw images on pictures. You can add different types of annotation, such as primitive shapes, text, freehand, sticky notes, redactions, images, hot spots, callouts, rubber stamps, and ink.
