Image cropping, framing, resizing and saving in JPEG format
You
can crop, frame or resize images and save them in JPEG format. If an image was
shown with a resolution smaller than the original in order to fit in the screen
size, you can chose to save the altered image with the original resolution or
the new resolution resulting from adaptation to the screen size. The following
three figures show examples of cropped, framed and resized images.

Selecting
the alteration mode (cropping/framing or resizing)
Before
you manipulate the image you have to select the alteration mode by means of the
"Allow image dragging for cropping and inhibit resize" command in the
context menu. This command (which carries an on/off sign) allows you to set the
window in one of two possible states:
a)
Resize allowed and
cropping/framing inhibited (default state)
b)
Resize inhibited and
cropping/framing allowed. In this state the mouse pointer takes the shape of a
four point arrow
If
you need to resize and crop (or frame) the image, you should first resize it and
then crop (or frame) it, or the other way around.
How
to resize images
You
can resize the image by dragging the window borders or by pressing the
"+" and "-" keys. The initial height/width ratio will be
preserved.
How to crop or frame images
You
must first select the " Resize inhibited and cropping/framing allowed"
state (see above).
Then
you can crop or frame an image in various possible ways (choose the one easier
to you):
a)
By
dragging the image in any direction
b)
By dragging the
left or top borders of the window. In this case the image will follow the
movement of the border
c)
By dragging the
right or bottom borders of the window. In this case the image will not move and
an empty frame space will be added to the right or bottom, respectively
d)
By pressing the
direction keys (up, down, left, right) with the "upper-case" key being
pressed (this has the same effect as the above case
e)
By pressing the
direction keys (up, down, left, right) without the "upper-case" key
pressed. This is similar to the above case but the image will be dragged and
follow the movement of the right and bottom borders of the window
f)
By pressing the
"+" and "-" keys. This is like the above case, with the
advantage that with one key stroke you affect both the horizontal and vertical
movements of the window borders and of the image
The
time interval between subsequent strokes of the direction keys or "+"
and "-" keys will determine the number of pixels scoped by the
operation (one pixel if the time elapsed after the previous stroke is less than
0.3 second, otherwise 6 pixels.
Changing
the frame color
You
can change the color of the frame added to the picture by means of the relevant
command in the context menu.
Picture
coordinates
If
you shift the position of the upper-left corner of the image with respect to the
initial position (corresponding to the upper-left point of the window's internal
area), you can see the new coordinates (in pixels) of that point as two positive
or negative values within parenthesis after the file name in the window's upper
bar, as shown in the figures above (cropped and framed images). This may be
useful if you want to go back to the initial position (i.e. to the exact
"zero" left and/or top point) when manipulating an image.
Calling
external picture editor and auto-refresh
If
you need to manipulate the image in a way not supported by this program, you can
always call an external picture editor using the "edit picture"
command in the context menu. The configured external editor (you can configure
it in the image viewer main panel) will be called with the name of the image
file in the call line, so the editor will normally open the image automatically.
When closing the external editor, if the image file has been changed, an
auto-refresh will be performed and you will automatically see the image in its
new format.
Saving
pictures in JPEG format
You
can save images in JPEG format with the quality you prefer. If an image was
shown with a resolution smaller than the original in order to fit in the screen
size, you can chose to save the altered image with the original resolution or
the new resolution resulting from adaptation to the screen size. See the
relevant commands in the Image
(Non Full Screen, Framed) Context Menu.
