IMAQ Merge Overlay Problem

[Achuthaperumal]

Hello Everyone,

I'm trying to overlay lines in an image for publication. I'm facing a problem when I try to overlay angular lines. Please refer the image below.Overlay Result

My goal here is to make the Destructive overlay exactly as Non-Destructive overlay! Is it possible? Has this occurred to anyone? Any help would be really appreciated! Thanks in advance...

The non destructive overlay is a vector rendered by Labview which is why it still looks smooth when zoomed in. Merge overlay will rasterize that line. You can copy the view of the display with the current zoom level by right clicking > Data Operations > Copy Data and paste it as a bitmap image.

If you want to save the image to file with the overlay and present it again with Labview you could use the option PNG with Vision Info. Be sure to read with Vision info as well.

Hi RamonG,

Thanks for your reply!

Actually, I knew that concept! but the End Customer asks it in jpeg/bmp/tiff/png and they will use normal image viewer...

ImageJ is public domain and supports ROIs and overlays. It would be a challenge to save the overlay/ROI data using Labview to TIFF though. Maybe with LibTIFF.

Hi RamonG,

Actually there's no need for that I guess! Currently I'm trying with .NET Picturebox in LabVIEW... I'm very close to finding my solution! I'll let you know If I find an appropriate method for doing it.

Thanks for your effort! Really Appreciate it
