Digitize

Digitizes curves from a hard-copy.

Format:

SPECTRA> change scan_name
SPECTRA> digit$*$ize /bo$*$ard

Description:

The user has to change a SCAN before digitizing can be started. These nodes are connected to the board: HASYLB, VXDSYC and AXDSY$*$. The digitizing board can be found in room 113 building 25b. The following steps are necessary to digitize a curve from a hard-copy:
SPECTRA> create temp 0 10 1000
A SCAN that is will receive the digitized points is created. It is important to make it long enough.
SPECTRA> change temp
The user has to adjust the window limits to the one on the hard-copy. Make sure that the scale type is correct (linear, log).
SPECTRA> digit/board
SPECTRA prompts the user to mark three corner positions before the digitizing mode is started. Button 1 creates single points. Button 2 is used to start the stream mode. Digitizing is finished by pressing button 4. SPECTRA responds to every new points by ringing the bell.

/repeat

This qualifier directs SPECTRA to use the previous corner positions.

Format:

SPECTRA> change scan_name
SPECTRA> digit$*$ize

Description:

SPECTRA expects input from the gin-cursor. The left button adds a new point, ctrl-z ends the input. This command is obsolete after the DIGICAD board has been installed.

/append

The digitized points are appended to the SCAN. Otherwise the SCAN is overwritten. Points can only be appended, if the current index of a SCAN is below the total index. A SCAN can be extended with the command copy/np=... .

/display

A display command is executed before the gin cursor becomes active.
