bitmap overlay

[Ted King]

Hi there,

I'm having an 2048 x 4000 grayscale image. If I overlay the image with an RGBA bitmap it works well as long as the magnification

is 1/1 or lower (1/2, 1/4, etc.). For a magnification of 2/1, 4/1 or higher, the bitmap overlay suddenly disappears and scrolling becomes slow.

What's going on here ?

Hi Ted,

Could you post a example so we can take a better look at it?

Thanks

Hi Karsten,

I've attached the source with an image.

Thanks for your help !

Hi Ted,

I've been able to reproduce the issue. I did some checking and the issue has recently been reported to R&D to be investicated.

As a work around you can use the Overlay Points VI  instead of the Overlay bitmap vi.

Thanks
