XCAP is a family of sophisticated, interactive, imaging programs specifically designed to support the PIXCI series of imaging
boards, but also able to process and analyze images from other imaging sources. Several versions of XCAP are available:
XCAP-Std, XCAP-Plus, XCAP-Lite, and XCAP-Demo. All versions share the same user interface and menu structure, but
selected features in XCAP-Std, XCAP-Lite, and XCAP-Demo are not operational. XCAP is distributed on CD, diskette(s), or
downloadable from the EPIX, Inc. website. After installation, a 12 character identification code
[5]
is entered to configure XCAP
as either XCAP-Std, XCAP-Plus,
[6]
, or XCAP-Lite; or, lacking a valid code, configured as XCAP-Demo to browse, but not use,
XCAP's features.
XCAP-Std is an interactive, imaging program designed for scientific, industrial, and machine vision applications. XCAP-Std
supports the PIXCI imaging board, providing video format and resolution configuration; continuous (live), video rate sequence,
and triggered capture; and single or sequence, zoomed or resized, display. The image frame buffers of PIXCI imaging boards can
be loaded, examined, processed, analyzed, measured, printed, annotated, and saved.
XCAP-Std also allows loading and analyzing a pre-existing image or image sequence with size, pixel depth, and color space
independent of the PIXCI imaging board's configuration; XCAP-Std can be used with pre-existing images even when the PIXCI
imaging board is not present. XCAP-Std can also acquire images from TWAIN compliant devices.
XCAP-Plus provides extra, advanced, features in addition to all of the capabilities of the XCAP-Std, such as support for
specialized, optional, hardware.
XCAP-Lite is a basic version of XCAP-Std. XCAP-Lite provides similar image acquisition and PIXCI imaging board control
capabilities, video format and resolution configuration; continuous (live), video rate sequence, and triggered capture; and single
or sequence, zoomed or resized, display. XCAP-Lite also provides some of the image loading, examining, printing, and saving
features, but minimal processing, measurement, analysis, and scripting features are functional. XCAP-Lite can also be used with
pre-existing images, but only while the PIXCI imaging board is present and opened for use.
XCAP-Demo allows browsing through the dozens of processing, measurement, analysis, and graphics features provided in
XCAP-Plus, XCAP-Std, or XCAP-Lite. Images can't be loaded from, or saved to, files. Nor can the PIXCI imaging board be
operated with the XCAP-Demo version.
As XCAP-Plus, XCAP-Std, and XCAP-Lite share many common features, this manual typically refers to all versions as XCAP,
except where explicitly differentiated.
The XCAP programs are organized into two major types of windows, the Image Viewer Window and the Main Window.
For each image, or sequence of images, an Image Viewer Window shows that image, or a selected image of that sequence, and via
its menu bar allows viewing, examining, processing, analyzing, or drawing upon that image (sequence). The Image Viewer
Window associated with the PIXCI imaging board's frame buffers also provides features for capturing new images. There can be
multiple Image Viewer Windows for the same image (sequence), allowing, for example, viewing the image both zoomed and
unzoomed, or simultaneous viewing of different images of a sequence.
The Main Window allows creating new image (sequences), and thus new Image Viewer Windows, either by loading a new image
from file, explicit specification of the new image's dimensions, or by opening the PIXCI imaging board for use. Video setup for
the PIXCI imaging board, such as modifying the video resolution or color space, are also in the Main Window; these features
destroy and re-create the PIXCI imaging board's Image Viewer Window. The Main Window also provides features not directly
associated with an image (sequence), such as scripts, RS-232 device control, and features to customize XCAP.
5.1. The Main Window
The XCAP main window provides a menu bar with
File
,
Images
,
Scripts
,
Utility
,
PIXCI®
, and
Help
features.
5.1.1. Main Window - File
The main window's
File
allows loading of pre-existing images into new image buffers, displaying attributes about pre-existing
images, and acquiring images from TWAIN compliant devices.
The
Load New Image
and
Load New Image Sequence
creates a new image buffer (sequence) with dimensions, pixel depth, and color
space matching a specified TIFF, BMP, or multimedia format file(s), and loads the image(s) from the file(s). This feature, and the
image buffer (sequence) created, is unrelated to the PIXCI imaging board's frame buffers. After creation and loading, the new
image (sequence) is displayed, processed, and analyzed in
The Image Viewer Window
, described below. The
Load New Image
can
also load images directly from an Internet URL. The XCAP-Lite version does not provide the
Load New Image Sequence
or
loading directly from an URL features.
The
Image File Info
displays information about a specified TIFF or BMP format file without loading the image. The information
displayed includes the image's dimensions, pixel depth, color space, palette option, and other file format specific information.
