The image viewer window's
Draw
provides features for drawing graphics and text over the image. One or more of: line, circle with
aspect ratio correction, rotated rectangle, rotated ellipse, arc of circle with aspect ratio correction, arc of rotated ellipse, annulus,
arc of annulus, rectangular frame, list of points, polygon, polyline (connected line segments not closed into a polygon), Bezier
curve, or Bezier region (Bezier curve closed to form region), rotated text, and arrow may be overlayed over the image (non
destructive) or written into the image. The individual menu items such as Text, Line, Rectangle, etc. allow quick drawing of
graphics or text. The
Graphic Manager
permits drawing the same graphics or text, but in addition manages a list of graphic or text
objects, including loading and saving of the graphic or text objects.
The
Image Overlay
feature allows overlaying a second image, containing graphics on a ''transparent'' background, over the current
image.
The
Paint Brush
feature allows interactive ''painting'' onto the image with selectable color, patterns, and ''brush'' shapes.
The
Paint Fill
feature allows filling (flooding) an image region with ''paint'' of selectable color and patterns, using specified pixel
values as the boundary terminating the ''filling''.
The XCAP-Lite version only provides the graphic line feature.
5.2.7. Image Viewer - AOI
The image viewer window's
Aoi
allows defining areas of interest (AOI) and regions of interest (ROI) upon which future image
processing, measurement, analysis, print, load, and save features will operate. As used in XCAP, an ''AOI'' is a rectangular area
with sides parallel to the image axis, while an ''ROI'' is of arbitrary shape, such as an ellipse or rectangle which may be rotated
with respect to the image axis, or an arbitrary path or polygon. The image print, load, save, and many other features only allow
use of an AOI; selected image processing, measurement, analysis and other features also allow use of an ROI.
The
Set AOI
defines the default area of interest and color space upon which future image processing, printing, load, and save
features will operate.
The
Set ROI
defines the default region of interest and color space upon which future image measurement, analysis, and other
selected features which accept an ROI will operate.
The
Set Full Image
quickly sets the default area of interest and region of interest to the image's full dimensions, and the default
color space to the image buffer's natural color space, without entering the
Set AOI
or
Set ROI
window.
The
AOI/ROI Manager
maintains a list of often used areas of interest (AOI) and regions of interest (ROI).
Within each of the image processing, measurement, analysis, print, load, and save features a different AOI (or ROI, if applicable)
can be selected, temporarily overriding the default AOI (or ROI). Within the feature, the new AOI (or ROI) can be specified
numerically or interactively drawn, or an AOI (ROI) previously defined within the
AOI/ROI Manager
can be selected.
5.2.8. Image Viewer - View - Shortcuts
A tool bar of icons provides shortcuts for accessing often used features of
The Image Viewer Window
. Selected shortcuts can also
be activated by key clicks when the tool bar window as the ''input focus'' (e.g. Windows has highlighted that window's title bar).
The shortcuts provided are:
Switch to first buffer of sequence (
Key HOME
).
a.
Switch to next buffer of sequence (
Key PAGE UP
).
b.
Switch to previous buffer of sequence (
Key PAGE DOWN
).
c.
Switch to last buffer of sequence (
Key END
).
d.
Copy image to new image buffer.
e.
Adjust palette.
f.
Zoom, scroll, and pan.
g.
Peek at numeric pixel values.
h.
Two dimensional plot of line or column of pixel values.
i.
Histogram of pixel values.
j.
The first four shortcuts appear only for
The Image Viewer Window
s which access a sequence of images.
The shortcuts may either be attached and part of
The Image Viewer Window
, or may be detached into its own window, as set by
Display
under
Image Viewer - View
.
5.2.9. Image Viewer - View - Status Bar
A status bar provides information about the image resolution, current cursor coordinates, current buffer of a sequence, and other
