The
Full Screen
allows displaying the image in the full S/VGA screen, with little or no window ''frame'' around the image. A mouse
click, anywhere on the S/VGA, restores the previous mode. The XCAP-Lite version does not provide the
Full Screen
feature.
The
Always-On-Top
allows forcing the image viewer window, and its subwindows, to always be ''above'' other windows; subject to
the other windows' also requesting
Always-On-Top
, and the whims of the host operating system. This option is typically useful only
when XCAP is being used in combination with other applications, such as in conjunction with the PIXCI® TWAIN Sourcery or
PIXCI® Image-Pro Sourcery feature.
The
Refresh
forces the displayed image to be redrawn once; normally manual refresh is not needed, but occasionally, when the
image was (partly) covered and uncovered by other window(s), the displayed image might ''forget'' to be updated.
For images composed of index pixels and palette, the
Image's Palette
allows manipulating the image's attached palette; for images
of other types, the
Image's Palette
is not selectable. For all images, the
Viewer's Palette
allows manipulating a palette which is not
attached to the image. Either can be used for contrast enhancement, adjustment of black level and gain, or, for monochrome
images, false coloring. Either, or neither, of the palettes can be selected for use under
Misc Options
.
For image sequences, the
Sequence Play
allows ''playing'' the sequence, image by image, at a selected rate. The
Sequence
Thumbnails
shows a window in which each image of the sequence is a small ''snapshot''; clicking a snapshot selects that image for
display by the image viewer window. The XCAP-Lite version does not provide the
Sequence Thumbnails
.
The
Cursor
allows activating a cursor over the image, which may be positioned via coordinates, or by clicking the mouse on an
image feature.
The
Display
allows selecting how the image is displayed: (a) No resizing so that there is a one to one relationship between an
image pixel and a displayed S/VGA pixel and is quickest, although the entire image may not fit within the window and must
therefore be panned and scrolled, (b) Resize by nearest neighbor which is relatively quick, or (c) Resize by bilinear interpolation
which may produce better results for continuous tone images, but is slower. For the resize modes, the aspect ratio can also be
modified. For the image viewer window associated with the PIXCI imaging board's frame buffer(s), the
Display
provides
additional features, identical to the
Live Options
described below.
The
Zoom, Pan, Scroll
allows magnifying the displayed image, and panning and scrolling to view different portions of the image
under magnification. For image sequences, a specific image of the sequence can be selected for display. In addition to panning
and scrolling via explicit coordinates and via scrollbars, holding the right mouse button and moving the mouse over the image also
implements panning and scrolling.
The
Misc Options
allows selecting which palette, if any, is to be used during display and during file loads and saves. An option to
display only even lines, or only odd image lines, allows avoiding interlace artifacts during display.
Each image buffer (sequence) may have several simultaneously active viewers, allowing, for example, viewing the same image
buffer both magnified and unmagnified. The
Launch 2nd Viewer
creates a second image viewer window into the same image buffer
(sequence), with the same features as the original image viewer window. The XCAP-Lite version does not provide the
Launch 2nd
Viewer
feature.
5.2.3. Image Viewer - Examine
The image viewer window's
Examine
provides options to examine the image.
The
Pixel Peek
allows numeric display of the pixel values in the vicinity of the image cursor.
The
Pixel Peek & Poke
allows numeric display and modification of the pixel value at the image cursor.
The
Pixel Plot
displays a two dimensional graph of pixels values along a selected image line or column, all image lines, or for
image sequences, a vector. Features attached to the graph show specific pixel values and descriptive statistics such as lowest
value, highest value, mean value, and standard deviation. The XCAP-Lite version does not provide a graph of all image lines, and
does not provide descriptive statistics.
The
Pixel Plot 3D
displays a three dimensional graph projection of the image.
The
SMPTE VITC
allows searching the image for valid SMPTE Vertical Interval Time Codes and displaying the decoded codes.
The XCAP-Lite version does not provide the
SMPTE VITC
features.
5.2.4. Image Viewer - Modify
The image viewer window's
Modify
provides image processing operations which modify the image, modify each image
(independently) in a sequence (typically named ''Sequence ...'') or modify one or more images in a sequence by combining data
from across multiple images (typically named ''... Sequence ).''
