Windows Description

The digitization is being performed in interactive regime, supported with set of pop-up windows.

Main window (Scanned signal digitizing) contains the canvas image, buttons for setting the time scale, and also the buttons, which are used continuously during the trace digitizing.

Etc window ("et cetera") contains the means for reading the file, tuning the parameters, setting the options and other buttons, which are used relatively seldom.

Eraser window is used during the rectifying the canvas. It contains the control buttons and choice for selection of the eraser's geometry.

Save data window is used for forming of output .wfdisc files.
Arc window (Transforming to rectangular coordinates) is used for conversion of arched image to rectangular one, so the single admissible source form for the digitization is a rectangular image.

Main window

Main window contains a canvas for seismogram image and panel with several panel's tools. The Main Window Control Buttons are divided into two horizontal sets of ones. The upper set includes the following:

Etc

Rotation

Creates a new display Window for image rotation.

Arc_to_rectangular

Eraser window

Eraser window is used during the rectifying the canvas. It contains the choice buttons for selection of the eraser's geometry shape and some control buttons:

Apply

Causes the completion of erasing of the whole image, re-reading of the pcx-file.

Close

Suspends the erasing and save the erasing square list. Causes the disappearing of the window.

Eraser geometry

Set the geometry form of the Erasing zone, which can appear as square or circle contour.

Deny last
