Selections

Brief description: To perform different operations - such as edit, modify an object's properties with the Inspector, and others - you need to select data to apply commands to. In this section we consider raster and vector data selection technology. You will learn about different selection modes, methods of data selection, and tuning raster selection.

You can select raster, vector and hybrid (both raster and vector) data in WiseImage. Selection technology and data selection methods for all data types are extremely close to vector object selection technology.

WiseImage allows selection of the following data and their combinations:

  • Vector objects (raster images are included)
  • Raster data:
    • Raster objects (raster lines, arcs, circles, selected with object selection methods, which have “grips”, properties and precise geometry).
    • Area fragments of the raster image.
      • Selected with window or polygon.
      • Raster line segments of arbitrary shape. (A segment represents part of a raster line of arbitrary shape, limited by points of intersection with other raster lines or endpoints).
      • Isolated raster fragments.
  • Hybrid data (both raster and vector data selected).

You can use the Selection and More Selection toolbars to select data.

IMPORTANT: When selecting data, you need to define three parameters:

  • Type of data to select- raster, vector or hybrid

See section Type of data selected for detailed information.

  • Selection modes - add to selection, remove from selection, single selection.

See section Selection modes for detailed information.

  • Selection method - by picking, within window, crossing polygon and others.

See section Raster Selection Methods for detailed information.

Table 1 Type of data selected, selection modes

Type of data selected

You need to define the type of data to select (raster, vector or hybrid) by pressing the corresponding button on the Select toolbar.

 To select vector objects and raster images, choose Vector Selection
To select raster data, choose Raster Selection
To select hybrid data, choose Hybrid Selection

Selection modes


 New data is added to selection
Selected data is removed from selection
Every new selection deselects previously selected data
Selects all vector objects in WiseImage document (except raster images)
Selects the contents of all raster image in WiseImage document
Selects all objects in WiseImage document (raster images are included)
To deselect all selected data choose Deselect All

Raster Selection Methods

Table 2 Selection methods

Object selection methods of vector and raster data

You can select vector and raster objects (raster lines, arcs, circles) using object selection methods:

 By Picking (Auto)
By Crossing Window
Within Window
By Crossing Polygon
Within Polygon
By Fence

You can also select raster objects by reference objects:

 raster line or its segment by 2 points
raster arc or its fragment by 3 points
raster circle by two points

How to obtain the raster area selection using object selection methods:

IMPORTANT: If you need to obtain an area selection when selecting raster objects press Raster Area Selection , located on the Select toolbar.

Raster Image Selection

If you need to select the raster image, specify (cross) its frame, choosing vector (hybrid) type of data selection.

If the document contains several raster images and you need to select some of them use Select Raster on the Select toolbar.
Choose Select Image button, located on the Select toolbar

  • Select desired raster images from the list
  • Close the Select Raster window

Selecting raster area fragments

Selecting inside rectangle or polygon

You can select rectangular or polygonal fragments of the raster image area using Select by Rectangle or Select by Polygon button, located on the Select toolbar. You can select:

  By Picking (Auto)
 By Crossing Window

Selecting raster segments

Segment represents part of a raster line of arbitrary shape, limited by intersection points with other raster lines or endpoints.

You can select raster line segments:

  Within Window
 By Crossing Window
 Within Polygon
 By Crossing Polygon
   
 By Fence

Selecting isolated raster fragments

You can select isolated raster objects:

  By picking
 By Crossing Window
 Within Window
 By Crossing Polygon
 Within Polygon
 By Fence

Tuning raster selection

You need to tune the geometry of raster data to obtain the best results when selecting raster objects and raster segments.

How to tune the raster selection:

The selection geometry is tuned using the R2V Conversion Options dialog.
To open this dialog, choose Conversion Options from the Convert menu.


 
Specify the following values in the Options tab:
Max. Width - maximum width of raster object to select. Specify this parameter value slightly greater than maximum width of raster objects or raster line segments.
Max. Break - length of ignored break in raster lines.
Accuracy - your document accuracy. For example, if when selecting a raster circle by picking, the program only selects its fragments (arc), reduce the accuracy value

Filter for data selection

You can select data, grouping them by type, colour, and layer

To select a group of objects, choose Select Objects with Filters  button on the Select toolbar.
Then select a desired object type from the Type list.
INFORMATION: Type includes only those types of objects, which are contained in the document.

You can group objects of a selected type by color and layer.
