Changes in AutoCAD Standard Functions when Working with
WiseImage
AutoCAD tools do not allow you to change raster images, but WiseImage
commands can create new images, edit and save all types of raster images,
supported by AutoCAD. The standard AutoCAD functions for managing raster
images are changed as follows:
AutoCAD Function
Deleting raster images
Unloading raster images If there are unsaved changes, then WiseImage prompts
Saving an AutoCAD

Exiting AutoCAD

Inserting and Scaling Raster Images

You can insert raster images with the AutoCAD command IMAGEATTACH
that can be run from the WiseImage toolbar
Insertion of a raster image is performed using the IMAGE command. When
inserting, you can specify a scale factor, rotation angle, and insertion point. Images
can be placed either in the paper space or model space of AutoCAD.
For more information on raster image inserting, see the relevant AutoCAD
*
section.
When editing and performing vectorization of raster images using WiseImage tools,
the most convenient way to manage images is to insert them in the drawing at a
scale of 1:1. This is a scale, which matches one "sheet" millimeter (inch, or another
measurement unit) of a raster image to one AutoCAD measurement unit. Such a
method facilitates the setting of numerical parameters and plotting. In this case a
user manages a scanned image as if it were an original sheet drawing or a map.
See below for a description of image insertion at a scale of 1:1.

If there are unsaved changes, then WiseImage prompts
you to save these changes.
you to save these changes.
WiseImage automatically saves all changed raster
images inserted into the current drawing. If new images
were created, then the program opens a dialog box for
saving a new raster image, where a user should specify
the raster file name, location and format.
WiseImage saves all changed raster images in case the
drawing is saved.
