6. Removing features¶
The diagram part is converted to a binary image where everything black (i.e. 1) represents data (see Selecting the reader). So before the data is digitized, features that do not represent data have to be removed.
Here, you can either use the features of the selection toolbar, or you use one of the automatic removal tools we provide here. Note that you can edit every selection using the mouse selection tools or the automatic tools from the selection toolbar.
After you selected the features to remove, click the Remove button at the bottom of the straditizer control panel.
