9. Finding and editing samples

So far, we have one data point per pixel in the image. However, we have to identify the locations of the samples in order to reproduce the original data.

Straditize assists you with this through automatic sample finding algorithms, or you can load the sample locations from an external files or you just add and edit the samples manually.

1. Expand the Samples item in the digitization control

2. Find the samples by clicking the Find samples button. straditize now identified the sample locations based on the extrema in the columns (see Automatic samples identification for an explanation of the algorithms).

3. To visualize the samples, you can again use the items in the Plot control tab. However, you can (and should!) also edit them by clicking the Edit samples button.

4. Now you see one horizontal line per sample that you can drag around (left-click), delete (right-click) or you can also add new samples (Shift + left-click). See the Editing samples section for more details.

5. Finally, click the Apply button or the Cancel button to stop the editing of the samples.

You’re almost done! Your diagram is now digitized and the data could already be exported.
