The
TWAIN Select Source
and
TWAIN New Acquire
allow using XCAP as a TWAIN Application, acquiring images from TWAIN
compliant imaging devices (TWAIN Sources). The
TWAIN Select Source
allows selecting which TWAIN Source is to be used, and
the
TWAIN New Acquire
allows acquiring one image from the TWAIN Source. The XCAP-Lite version does not support being used
as a TWAIN Application.
The
Window List
displays a list of active windows belonging to XCAP; selecting a window causes that window to appear, if
previously hidden, and/or to appear over other windows (subject to the priority of selected windows to always appear ''on top'').
5.1.2. Main Window - Images
The main window's
Images
allows creating new image buffers and activating any existing image windows that may not be
on-screen.
The
New Image
creates a new image buffer, or sequence of image buffers, with specified dimensions, pixel depth, color space, and
palette. This feature, and the image buffer created, is unrelated to the PIXCI imaging board's frame buffers. After creation, the
new image is displayed in an
The Image Viewer Window
, as described below.
Underneath
New Image
are listed all existing image windows, whether for PIXCI imaging board frame buffers, or for independent
image buffers. (The image window for PIXCI imaging board frame buffers appears only after the PIXCI imaging board has been
opened for use, see below). An image window which has been closed and thereby off-screen can be reactivated by clicking the
image window's name.
5.1.3. Main Window - Scripts
The main window's
Scripts
provides features for recording and playing scripts. A script recording contains most of the user's
interactions with the windows of XCAP; playing the script duplicates the original actions.
Some user actions are not recorded. Using the mouse to drag the cursor or other graphic across an image is not recorded as these
actions are highly dependent upon image content (such as the typical scenario of dragging the cursor until it is positioned next to
an artifact in a captured image), would likely be inappropriate to other captured images, and would consume a significant amount
of disk space. Instead, after positioning the cursor interactively the user can record the final position by clicking the appropriate
numeric cursor coordinates. Features activated with keys, or clicking icons are not currently recorded; such features can also
activated by other means, which are recorded.
A recorded script is in a human readable form and can be altered with any common editor capable of handling ASCII text,
allowing scripts to be modified or combined. A selected script may be executed automatically after XCAP starts, this feature is
set in
Utility
,
Program Setup
,
Startup Script
.
The
Load Tool Bar
provides one or more user-defined tool bars of shortcuts, each shortcut represented by an icon which, when
clicked, executes a user-specified script. Each shortcut may also specify an optional keyboard key which, when pressed, also
executes the user-specified script.
The
Script Remote Control
allows using XCAP as a hidden, off-screen, ''black box''; any end-user application that can manipulate
text files, can also remotely control XCAP.
The XCAP-Lite version does not support recording scripts, creating user-defined tool bars, or the remote control feature. The
XCAP-Lite version can play scripts previously created with XCAP.
5.1.4. Main Window - Utility
The main window's
Utility
provides an assortment of features which are of secondary importance; features which allow fine tuning
of XCAP, or features needed in relatively few circumstances.
The
Black Board
allows customizing XCAP, creating non-procedural programs, and collecting data. The black board allows inter-
connecting the numeric and text field of other windows; computed results, such as center-of-mass, may be written onto the black
board - parameters for other features, such as the coordinates of a displayed grid, may be extracted from the black board -
combining these automatically repositions the grid as the center of mass is recomputed! Other features allow computed values
(similar to a spreadsheet), ''push''ing buttons, timed updates, creating a report to file or an RS-232 port, collecting data, and
graphing the black board's contents. The XCAP-Lite version allows use of the
Black Board
for computing values (similar to a
spreadsheet), but does not allow inter-connections with other features or creating reports or graphs.
A
Message Log
window lists warnings and errors that arise from performing various operations. By default, the message log
window appears automatically when a message is added, and disappears a few seconds later. Auto appearance, auto hide, and
audible clicks can be disabled (from the message log window's menu bar). The menu-bar's
Message Log
allows explicit activation
of the message log window.
