This LAB is designed to create a layer by extracting portions of ordinary images.
The method used is unique to 3D Gugle and can not be compared with other known methods such as the "Magic Eraser" of Photoshop.
The layers used for stereo applications require the highest precision and operations which round edges or antialiase are not acceptable.
The method used by "Selection" is a process which operates automatically or manually with equal success.
The mouse can be used to correct or fill parts while the automatic process works in the areas of complex shape.
Using the right mouse button you can always restore and with the left button together with the "Control" key, you can fill large areas or correct imperfections.
The process also uses a zoom of great precision and quality that allows operation on finer details.
Remember also that the 3D Gugle has other laboratories and capacities to work with layers such as:
- Method "Box" or "By Points" to select
parts of image, see "BOX"
- "Combine"
to sum images and Layer maintenance .
- "Paint"
to do retouch or clone areas. .
- "Direct
Layers"
to extract the Layer so programmed.
- "Direct
Stereo"
to convert the Layer in 3D..
- "Layers
Assembly" Layer management and to
create stereo animations and stereo applications.
- "Algorithms
to Layers"
to deform the Layer or create Frames for animations.
-
"Write"
to create Layer with Text.
- "Pattern and
Texture"
to create infinite patterns and textures.
Load Image
With this menu you open the image from which to extract the Layer.
Save Screen as Image
To save a copy of the sceen image as normal Image.
The formats can be "bmp, png, tif, jpg, gna"
When the format "jpg" is used, the settings set with the "Preferences" of 3D Gugle are applied.
Save Screen as Layer
To save a copy of the sceen image as Layer.
The formats can be "bmp, png, gna".
When saving the screen image as a layer the filled areas will be automatically converted into the colour "Black" used by 3D Gugle to handle the transparencies.
In the example below the same image is saved as "Image" on the left and "Layer" on the right:
In the left image a pattern created with 3D Gugle LAB Pattern and Texture is used to fill the image

BOX Functions
On activating this menu there appears at
the centre of the screen, a BOX (Rectangle) which you can use to save or copy a
bounded area.
When the box is visible, other features are
available by clicking the right mouse button and at the top of the screen the
coordinates and the dimensions in pixels are shown.
To move or to modify the size of the Box you can use the mouse or the keys.
With
the Mouse
Move
When the cursor is inside to the rectangle the cursor changes to a crossed
arrow. To move drag the rectangle to a new position.
Resize
When the cursor is on one of the rectangle sides, the cursor changes to a double
headed arrow.
To resize drag the side of the rectangle.
With the keys
Move
The Arrow keys move the rectangle in the respective direction.
Resize
SHIFT + Arrow keys resize the rectangle for the side Right and the Lower side.
CONTROL + Arrow keys resize the rectangle for the Left side and the Upper side.
Copy As Layer and Copy as Image
Are important functions that allow you to test the layer immediately.
Normally "Selection" LAB work together
with 3D Gugle and the function "Copy" allow you to export in 3D Gugle the Layer to do
a real examination.
In 3D Gugle you import a Layer using the menu "Edit\Paste
Add Layer" or "File\Open Add Layer".
Centre BOX
This feature is used when the images are large, to avoid searching and
dragging the box to a new location.
Close BOX
Hide and close the Box
SETTINGS
Show a dialogue to set the work parameters.
Tolerance
Determines the sensitivity of the
automatic filling - typically 3 to 6.
Square Size
Determines the size in pixels of the box
in which the automatic filling operates. For very complex selections use values
ranging from 10 to 20 pixels.
"Colour", "Hatch", "Texture"
are buttons to select the method of filling.
Pressing these buttons opens a dialogue of different commands depending on the
filling method.
In many cases it may be convenient to work with
different types of filler in order to have the correct contrast so as to be able
to easily see the errors.
To change the method simply press a different button. The preview is immediate.
When working with a layer the filling is only to
highlight as best as possible the selected areas.
When you save the layer, regardless of the type of filler used, the selected
areas always will be converted into the black colour.
If you want to use the filling as an aesthetic function, save as "Image" (and not as "Layer"). In this case the saved image is an exact copy of what you see in the screen.
Fill "Solid colour"
Fills the selected area with a
uniform colour. To change the colour use the button "Change"
Fill "Hatch"
Fills the selected area
with different combination of lines.
The dropdown menu enables selection of one of 64 different combinations.
Every hatch uses two colours: the colour of the lines and the background colour.
To select different colours use the two buttons
"Change".
The left button is for the line colours.
Below an example of "Hatch" types.

Fill "Texture" or image
Fills the selected area using
any type of image.
The image can be replaced at any time.
To load the image use the "Load" button.
Below is an example that uses images for filling.

CURSOR SIZE
The menu sets the size and the cursor type.
The cursor defines the area where you operate manually, while the tip of the arrow cursor indicates the point of the automatic operations.
HOW TO
USE THE MOUSE
In the laboratory the
mouse is an essential device and to work quickly and accurately it is therefore
essential to understand the philosophy.
The mouse operates in two modes, manual and automatic.
Manual mode
With this mode it is possible at any time to correct errors or quickly fill
the areas selected.
To restore click the right button.
The mouse can work with the same mode as the "Direct
Layers"
and can therefore be used as a pair of
scissors that cuts the part to be removed.
To operate on small details reduce the diameter of the cursor and zoom the image using the menu "Zoom".
To fill an area press the "Ctrl" (control) and click the left mouse
button.
Filling an area manually is much more effective and faster than using an
automated process.
Automatic mode
With the automatic mode
you select areas of complex shape by giving the computer the selection job.
In automatic mode you can operate in different
ways. For example:
a) clicking
the left mouse button on the area to select
b) holding down the left mouse button to move in the area to
selected
c) holding down the left mouse button to move adjacent to the
contours of the area to select. This is also the preferred mode and the
guidelines of this project.
AN EXAMPLE OF SELECTION
To show the example of
selection, a relatively complex image has been chosen. It also contains JPEG
compression defects.
The image is this.
Procedure
1) From the menu "File\Load image" load in
"Selection LAB" the image to use.
2) Press the button "
3) Enlarge the image with a zoom 200% and reduce
the diameter of the mouse cursor.
Always use the automated process described above for the small areas - those
that were not selected in the first phase.
If required make corrections using also the manual method.
Here is our result.

Here is our result.
4) Now you can complete the job manually.
Adjust the diameter of the cursor using the menu "Cursor Size" and then hold
down "CTRL" key and the left mouse button recrossing the whole missing area.
When completing the work, change, for closer inspection, the colour used in the area of selection. Often dark defects are not as visible on a dark colour as those visible on a light colour.
This could be the layer:
