Getting started
Brief description: This lesson provides
you with a basic knowledge of WiseImage – using WiseImage commands, loading
and saving raster files, and tools to aid precision drawing.
To run WiseImage
- Click Start on the taskbar, then point to Programs.
- Click on WiseImage, then choose WiseImage from the folder.
AutoCAD starts automatically, and then WiseImage is loaded.
Using WiseImage commands
There are three different ways to run WiseImage commands:
WiseImage toolbars
Most of the WiseImage commands can be run from one of the WiseImage toolbars.
You can manipulate WiseImage toolbars with the standard AutoCAD TOOLBAR
command.
The WiseImage Menu
This menu contains all WiseImage commands.
The Command Line
Each WiseImage command can be run from the command line. All WiseImage commands
start with the character 'r'.
Example: rNew, rTrace.
While performing most WiseImage commands, you can use the cursor menu
for fast option selection. The cursor menu is displayed if you
right-click the mouse. The same menus are displayed if you right-click
on some of the dialog box elements. These menus contain commands which
can be applied to the selected element of the dialog box, or facilitate
character entry in the dialog box.
Working with Raster Images
You can scan raster images directly from the program, load existing images and
create new raster images. WiseImage can handle any type of raster image
that can be loaded into AutoCAD, with no size restriction.
Scanning with
WiseImage
You can scan directly from AutoCAD with WiseImage, if you are using a CONTEX
scanner or a scanner with a TWAIN-driver.
If several supported scanners
are installed, choose one with the Select Source command
of the rFile menu. Then start the Acquire
command. The displayed dialog depends on the scanner and driver version.
Loading Raster
Images
In AutoCAD 2000/2000i/2002 you can use the standard AutoCAD ImageAttach
command.
In AutoCAD LT2000/2000i/2002 you must use the rOpen command.
Creating New
Raster Images
You can create a new raster image. Choose New from the
rFile menu and specify the type, size, resolution and other
properties for the new image.
Saving Raster Image
To save the raster image, use the rSave or rSaveAs
command.
When you save an AutoCAD drawing,
WiseImage automatically saves all changed raster images inserted in it.
If new images have been created during the session, the program opens
the save new raster image dialog box, where the user should specify the
raster file name, location and format.
Selecting an Image
with WiseImage Commands
Most WiseImage commands require the user to first select the image(s) to be
operated on. Two standard selection procedures are provided: selecting
one image and selecting a group of images.
Selecting a Single Image
If there is only one available image in the drawing, it is selected automatically.
To select a single image, click on its border. If there are several images available,
you can select the required one using the following dialog box after running
the command:
If you move the cursor to the AutoCAD screen and
hold it over an image, its name will be highlighted in the list and it
will also appear near the mouse cursor. To select the image, click on
it.
Selecting Several Images
If there are several images available, you can select the required ones before
calling the command. In this case the operation will commence on the selected
images.
If you have not selected an image, the following dialog box, which lists all
available images, is displayed. You should select those to be processed.
Raster Snap
| WiseImage allows you to snap to characteristic points of raster objects. You
can only use raster snaps on a monochrome raster image. When you select
points on the image with the raster snap mode on, a square raster
snap pickbox appears on the cursor cross. Furthermore, you can
snap to both vector and raster objects at the same time. |
 |
| Raster Snaps use the same settings from the Object snap settings as AutoCAD
Vector Snaps. Snapping
to raster has a lower priority than snapping to vectors. You can also use running snaps and snap on demand. |
- To turn on running snap to the raster:
From the rImage menu, choose Snap
and then Raster Snap On;
select Running Snap in the Object
Snap tab of the Drafting Settings dialog
of AutoCAD.
- To turn on snap on demand to the raster:
Simultaneously press Ctrl and the right mouse button, and choose
Raster Snap from the list.
Tuning the raster snap
IMPORTANT: Raster snap quality is influenced by the
quality of your image.
You can tune raster snaps by using the R2V Conversion Options
dialog box. Choose Conversion Options from the rConvert
menu, and then go to the Options tab.
Specify the following values:
Max Width – the maximum width of a raster object, to which you want to snap to. Specify
this parameter value slightly greater than the maximum width of a
raster line.
Accuracy – this sliding scale corresponds to the accuracy of your raster image. Use
higher values for images of good quality and lower values for images
of poor quality.

To turn on the
running raster snap mode
-
Using the standard AutoCAD command (DDOSNAP) turn on one or several
object snap modes.
- From the rImage menu, select Raster Snap,
and then On.
To turn off
the running raster snap mode
In the rImage menu select Raster Snap and then Off
or click the button in the Raster Snap toolbar.
Using Templates
A template is a set of dialog box settings,
saved to a separate file. Template files are stored in corresponding subfolders
of the TEMPLATE folder in the WiseImage root folder. You can use templates
to save and restore command parameters.
