Overlay
Owning Palette: Vision UtilitiesInstalled With: NI Vision Development ModuleUse the Overlay VIs to overlay figures, text, and bitmaps onto an image without destroying the image data. Use these VIs to overlay the results of your inspection application onto the images you inspected.
| Palette Object | Description |
|---|---|
| IMAQ Overlay Points |
Overlays a point or an array of points on an image. |
| IMAQ Overlay Line |
Overlays a line on an image. |
| IMAQ Overlay Multiple Lines |
Overlays multiple lines, as either a polyline or a polygon, on an image. |
| IMAQ Overlay Rectangle |
Overlays a rectangle on an image. |
| IMAQ Overlay Oval |
Overlays an oval on an image. |
| IMAQ Overlay Arc |

| IMAQ Overlay Bitmap |

| IMAQ Overlay Text |
Overlays text on an image. |
| IMAQ Clear Overlay |

| IMAQ Copy Overlay |
Copies an image overlay from the source image to the destination image. If the destination image already has an overlay, this VI adds the source overlay to the existing overlay. |
| IMAQ Overlay ROI |
Overlays a region of interest (ROI) on an image. |
| IMAQ Merge Overlay |
Makes a nondestructive overlay part of the image content. This process creates a destructive overlay. The VI then removes the nondestructive overlay. The resulting image is an RGB image. |
| IMAQ Read Image And Vision Info |
Reads an image file, including any extra vision information saved with the image. This includes overlay information, pattern matching template information, and calibration information, as written by the IMAQ Write Image And Vision Info VI. |
| IMAQ Write Image And Vision Info |
Writes an image, along with extra vision information associated with the image, to a PNG file. This extra vision information includes overlay information, pattern matching template information, and calibration information. |
| IMAQ Get Overlay Properties |
Get the transformation behavior properties for a group of overlays. |
| IMAQ Set Overlay Properties |
Sets the transformation behavior properties for groups of overlays. |
