I'm only interested in a portion of the log, is there a way to crop the image in Didger so that I only need to calibrate the area of interest?

 

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:

  1. After importing and registering the image, click the image in the Plot window or Data Manager to select it.
  2. Click Image | Crop Image.
  3. In the Plot, drag a rectangle over the portion of the image you want to retain.
  4. 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:

  1. After importing and registering the image, click Draw | Rectangle (or Polygon) and draw a polygon over the area you want to retain.
  2. In the Plot window or in the Data Manager, click the rectangle to select it.
  3. Click Image | Clip Image | Current Polygon.
