Image cropping, framing, resizing and saving in JPEG format

Contents

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.
