WiseImage Objects

Brief description: This lesson illustrates the different objects with which WiseImage works - raster images and vector objects. Scanning, loading existing and creating new raster images. Creating vector objects, assigning and editing their properties. Creating user markers and symbols for floodfilling.

WiseImage can simultaneously work with vector objects, raster images, and selected fragments of raster and hybrid graphics.

Raster Images

You can scan raster images directly from the program, load existing images and create new raster images.

Scanning with WiseImage

You can scan directly from WiseImage, if you use a scanner provided with TWAIN-driver or a CONTEX scanner.
If several supported scanners are installed, choose one with the Select Source command of the File menu. Then start the Acquire command. The displayed dialog depends on the scanner and driver version. After scanning is finished, a new document with scanned images will be created.
IMPORTANT: If you want to scan an image and load it to the current document, use the New Image from Scanner command of the Insert menu.

Inserting Raster Images

To insert a raster image to a new document, choose Open from the File menu.
To insert a raster image into the current document, choose Image from the Insert menu.

Creating New Raster Images

You can create a new raster image in the current document. Choose New Image from the Insert menu. Specify type, size, resolution and other properties for the new image in the New Image dialog. Press OK

Vector Objects

Creating Vector Objects

With WiseImage you can create different types of vector objects. The draw vector commands are located in the Draw menu and on the Draw toolbar.
You can specify point coordinates, angles and distanced when you create vector objects on the screen or enter their values in the corresponding fields of the Inspector window. While vector objects are being drawn the program status line (on lower-left corner) displays tooltips.

Vector Object Properties

Every vector object has a set of properties (belonging to a certain layer; color, line width and line type; markers, etc.) and geometry; which can be specified, viewed and modified in the Inspector.

  • Default properties of newly created vector objects are set according to the document's properties.
    See section How to set up document properties for detailed infirmation.
  • After creation, vector object properties can be changed in the Inspector (or the Properties toolbar).
    The next created object inherits the properties of the previous one.
INFORMATION: The next created object will have the properties of the previously created one - if the Document Transparent radio button of the Properties mode section of the Inspector is on.

The next created object will have the default document properties, if the Command sensitive radio button is chosen.
INFORMATION:
The created vector object can inherit properties of the layer, on which it is created, if you specify By Layer in the corresponding fields.
See section Layer Manager for detailed information.
INFORMATION: Vector objects included in a block can inherit the block properties, if you specify By Block in the corresponding fields.


Basic Vector Objects

The commands used for creating vector objects are located in the Draw menu or in the Draw toolbar.

Point - is created by specifying on the screen or entering its coordinates in the corresponding fields of the Inspector

Line - is created by specifying two points or angle and length

Arc - is created by specifying three points; or center, start and angle, or by center, angle and radius

Circle - is created by specifying center and radius; or diameter; or three points

Rectangle - is created by specifying three points or two opposite corners

Polyline

You can create a polyline, which consists of line and arc segments. To draw an arc segment press the SHIFT key. To complete drawing a polyline choose the command
End Polyline
from the context menu, which appears if you right-click when drawing a polyline. The commands of the context menu also allow closing polyline and undo the latest drawn segment.
See section Editing Vector Polyline for detailed information.

Hatch

A hatch is created in a closed area, limited by vector entities (entity). The program hatches inward from the outer boundary. If it encounters an internal intersection, it turns off hatching until it encounters another intersection.

Thus, areas separated from the outside of the hatched area by an odd number of intersections are hatched, and areas separated by an even number are not.

How to create hatch:
Select objects - hatch boundary and start the Hatch command of the Draw menu.

Hatch types:
Hatch Fill
Cross Fill
Shape Fill
Solid Fill

Hatch Fill and Cross Fill are characterized by line width, step (distance between lines) and skew angle.
Shape Fill is characterized by the shape, distance between shapes (or hatch step) and skew angle of lines, along which hatch shapes are placed.
You can set the hatch type in the Inspector.
INFORMATION: A closed vector object (rectangle, circle, closed polyline) can have the Fill property.
How to fill a closed vector object:
Select a closed vector object and in the Inspector set Fill to True, after that you can choose a fill type and properties in the corresponding fields that will appear.

Text
How to enter text:
Choose the Text command from Draw menu. Texts are entered from the keyboard. The entered text string is completed by pressing ENTER.
See section How to set up document properties for detailed information.
You can also edit text parameters in the Inspector or the Font dialog.

You can open the Font dialog by pressing the  button, which appears if you click in the Text Font field of the Inspector.

Multiline Text
You can create, import and save multiline texts.
How to create multiline text:
Choose the Multiline Text command from the Draw menu. Enter text in the window. Press OK. Insert the text in the document by specifying the insertion point.
See section Vector Object Properties for information on setting Multiline text properties.

How to import multiline text:
Press Load  of the Edit multiline text window. Select and open the *.txt text file. Specify an insertion point for this text in the document on the screen or in the Base Point field of the Inspector.

How to export multiline text:
Choose Multiline Text. Open the Edit multiline text dialog. Press the Save  button.

Dimension

With WiseImage you can create the following dimensions: linear - vertical, horizontal and aligned; angular, radial and diametral.

You can create a dimension object to specify distance and angle, radius and diameter of vector and raster objects.

How to create dimensions:
Method 1

  • Select an object to create dimension.
    See section Selections for detailed information.
  • Choose a corresponding button on the Dimension toolbar.
  • You can tune the dimension parameters in the Inspector - while rubber line for specifying dimension position is displayed.
  • Specify the dimension position on the screen by left-mouse click.
  • If needed, edit the position of dimension lines and text using grips.

Method 2
You can use this method to specify all dimensions except angular dimensions between two lines.

  • Choose the corresponding button from the Dimension toolbar.
    Then:
For Dimension: Specify on screen
by click:
  Specify on screen by click:
Linear - Vertical, Horizontal and Aligned Two points to measure distance between them Edit parameters in the Inspector toolbar Dimension line position
Angular Vertex angle and its two sides Angle - outer or inner and dimension arc position
Radial and Diametral Arc center or circle center Point on the arc (circle)

IMPORTANT: When specifying points you can use object snap to raster and vector objects.
See section Object Snap for detailed information.

  • If needed, edit the position of dimension lines and text by using the grip.

Blocks

Block - is a named group of vector objects (block definition).
Unlimited number of blocks can be inserted in the document.
When inserting, you can rotate a block and change its scale.
Program supports unlimited block nesting (a block can not include itself).
When exploded, the block is broken into its component objects.
If you want to change all block insertion in the document, create a new block definition with the same name.

How to create block:

  • Open the Inspector toolbar.
  • Select vector objects.
    See section Object selection methods of vector and raster data for detailed information.
  • Choose Create Block from the Draw menu.
  • Enter a name for the block in the Block Name field of the Inspector.
  • Enter the insertion point coordinates in the Base Point field or specify it on the screen.

How to insert block?

  • Choose Block from the Insert menu.
  • Open the Inspector. Choose the block name from Block Name list of the Inspector.
  • Enter the insertion point coordinates in the Base Point field or specify them on the screen.

User Markers

You can create your own markers, which will be placed on the endpoints of such vector objects as lines, arcs and polylines.

How to create a new marker:

  • Draw a marker of the desired shape. You can fill it with solid floodfill.
  • Select the marker's elements.
  • Choose the Create Marker command from the Tools menu.
  • Press the button   in the open dialog box and specify a point to connect the marker to the line.
  • Specify a name for the marker and save it by pressing Save or Save As button.
  • The created marker appears in the lists of Start Marker and End Marker of the Inspector. It can be assigned to selected or created vector objects.

Shapes for floodfilling

You can create your own shape to floodfill closed vector objects or Hatch objects.

How to create a symbol for floodfilling:

  • Draw a shape for floodfilling. You can use solid floodfill to fill it.
  • Select the shape.
  • Choose the Create Fill Shape command from the Tools menu.
  • Save the shape with name using Save or Save As button.
  • The created shape appears in the Hatch Shape of the Inspector. You can select it from the list when creating hatch or Shape Fill.

Raster Drawing Mode

The Raster drawing mode enables you to draw raster representations of vector objects.

To turn on the raster drawing mode choose the RDRAW button, located in the right-lower screen corner.

IMPORTANT: There should be a raster image under the objects that you draw in raster drawing mode; otherwise the created objects will disappear.
