There are a few approaches to clipping or cropping an image in Didger; both approaches will retain the original image calibration settings. These approaches are not limited to log/curve images and can be applied to all imagery in Didger.
The first approach uses the Image | Crop Image command where a rectangle can be drawn over the portion of the image you want to retain.Here are the steps:
- After importing and registering the image, click the image in the Plot window or Data Manager to select it.
- Click Image | Crop Image.
- In the Plot, drag a rectangle over the portion of the image you want to retain.
- Release the mouse button to crop the image.
The second approach use the Image | Clip Image command, but requires a polygon to be drawn over the area of the image you want to retain prior to clipping. Here are the steps:
- After importing and registering the image, click Draw | Rectangle (or Polygon) and draw a polygon over the area you want to retain.
- In the Plot window or in the Data Manager, click the rectangle to select it.
- Click Image | Clip Image | Current Polygon.
