Editing WiseImage objects
Brief description:
In this section you will learn different methods of editing selected
data - raster, vector and hybrid, and also the commands designed for editing
raster images and vector objects, including vector polylines.
Editing data, selected with object selection methods
If you select data with the object selection methods:
- You can view and edit the properties and geometry of selected objects
using the Inspector.
 |
 |
You can change the geometry of raster and
vector objects and also the location of selected objects on screen
using grips. |
| Selected raster object |
 |
| The raster object properties
in the Inspector |

- You can change the geometry of raster and vector objects and also
the location of selected objects on screen using grips.
- You can apply the following edit commands to selected objects:
The commands are located in the Modify and Correct
menu.

- FALSE, enter a desired value in the Distance field.
To align angles and distance between the lines:
- - AutoResizing
- TRUE.
Move the cursor to the line, relative to which you want to align
the others. If you are satisfied with the rubber lines position,
press the left mouse button.

Editing vector objects
Trim, extend, break vectors
You can use the following objects as a cutting edge -
for trimming, extending, or breaking vector objects:
- Vector or raster object
- Pre-defined Edge .
In case you use a vector or raster object as cutting
edge:
- Select the object(s)you want to use as cutting edge.
See section Object selection methods of vector
and raster data for detailed information.
- Choose the command - trim, extend or break from the Correct
menu or on the Vector Correction toolbar.
- Specify the vector objects one by one to apply the command to.
In case you use pre-defined Edge as cutting edge:
- Define Edge
- Select vector objects to form Edge.
- Choose Group/Ungroup Edge command from the
Correct menu.
- Select vector objects to edit.
- Choose the command - trim, extend or break from the Correct
menu or on the Vector Correction toolbar.
Editing Vector Polyline
The polyline editing commands are located on the Edit
Polyline toolbar, and also in the context (right-button) menu.
Select a polyline to edit.
You can apply the following commands:
|
|
Close polyline by joining end nodes
|
|
|
Close polyline with a new segment, which connects
end nodes
|
|
|
Add a new vertex at a specified point
|
|
|
Break polyline at a specified point or node
|
|
|
IMPORTANT: The following operation requires the selection of polyline
nodes. For this, you need to press the Node Selection
button of the Select toolbar.
Now you can select polyline nodes by mouse click.
|
|
|
To delete a polyline node, select it and press the Delete
node button
|
|
|
Joining two polylines:
|
by connecting specified end nodes with linear segment
|
|
|
by connecting specified end nodes with arc segment
|
|
|
by joining specified end nodes
|
|
|
Transforming a specified arc segment to a linear
segment. To specify a segment, click on its first node; nodes are
numerated from the polyline start.

Editing Raster Images
The commands from the Image menu are designed
for editing raster images.
The commands from the Image menu modify the raster image
contents - resolution, real size, size in pixels, points' positions.
IMPORTANT: You should know the difference between the editing commands
of Modify menu (see section Editing WiseImage objects ),
and those of the Image menu.
Unlike the commands of the Image menu,
the commands of the Modify menu do not change the raster
image contents. For example:
- The Scale command of the Modify menu only
changes the scale of raster display in the document; the raster image
contents (resolution, number of points and location), is the same.
- Using the Scale field of the Resample dialog
box, you can modify the raster image contents - resolution and/or the
number of points the image is composed of.
Change Image Size
Choose Change Size from the Image
menu.
Using the Change Size dialog box you can:
- Change the image size to the desired format.
- Choose the desired format from the list of Standard Paper
Size. Set orientation - Portrait or Landscape.
- Change the image size to the closest standard format.
- Press the Find Closest button.
You can edit the list of standard formats
using the Preferences dialog box. See section Customizing
Program Parameters for detailed information.
- Add (cut) image margins.
- Specify values to add (cut) margins in the Alignment/Margins
section.
You can also align the image position relative to its
margins:
- Using one of the nine buttons of the Alignment/Margins
field.
- Entering the margins values in the Alignment/Margins
section with the Fixed Size checkbox set to on.
Resample
Choose Resample dialog from the Image
menu. Using the Resample dialog you can:
- Proportionally change the image size with fixed resolution.
- Choose measurement units from the list; you can choose pixels
as measurement units.
- Enter the new values in the Width and Height
fields.
- The Fixed size in pixels checkbox is off.
- Change the image size according to specified Scale value with fixed
resolution.
- Enter the new scale value to the corresponding field.
- The Fixed size in pixels checkbox is off.
- Change the image resolution with fixed size.
- Enter the new resolution value to the corresponding field.
- The Fixed size in pixels checkbox is off.
- Change the image resolution (size) with fixed number of pixels.
- Select the Fixed size in pixels checkbox.
- Enter the new resolution (size, scale) value.
Cropping Image
Cropping commands are located in the Crop
submenu of the Image menu.
You can:
- Crop blank margins of the raster image.
- Crop the raster image by its frame.
- Crop the raster image by a rectangle specified on the screen.
- Crop the raster image by pre-defined clip.
See section Image Clip for detailed information.
Rotate and mirror
These commands located in the Image menu,
allow you to rotate an image by 900, 1800, 2700,
or by an arbitrary angle; and also mirror an image about X-axis or Y-axis.
The other commands for editing raster images are
provided in section Ehhancing Scanned Images.
Search and Replace
Search and replace operations allow you to:
- Find raster fragments and replace them with other fragments or vector
objects.
- Find vector objects (which can consist of lines, arcs, circles, and
polylines) and replace them with other vector objects.
How to perform search and replace:
- Choose Search - Replace from the Edit menu.
- Define a sample for searching - raster or vector fragment, and then
place it in the Find What field of the Search -
Replace dialog box.
- Define a sample for replacing - raster or vector, if you search for
raster fragment; and only vector, if you search for vector fragment.
- Set the accuracy value.
- The position of the Accuracy slider defines the deviation
of found objects from the sample for searching.
- Select the Erase checkbox to erase original elements.
- Select the Only Standalone Symbols checkbox to search
for only standalone raster objects or vector symbols.
- Press the Find button to search and replace symbols
one by one.
Press the Replace All to search and replace symbols in
automatic mode throughout the entire document.
