Autotek autocad raster design 2010 ユーザーズマニュアル

You can adjust the size and location of an image at any time after inserting
it into a drawing.

For instance, you may need to correct distortions caused by scanning errors.
There are several ways to ensure precise correlation of an inserted image:

■

Match points on an image to points in your drawing in order to scale or
rotate a raster image.

■

Displace an image, to move it in reference to existing raster or vector
entities without scaling or rotating it.

■

Scale a raster image without rotating it.

■

Rubbersheet an image to eliminate distortion and stretch or shrink a
portion of your image to align with selected control points.

You can match points between two images or between an image and a vector
drawing to change the image scale and position.

The image size and orientation change to align the selected match points.

1 Click Image menu  ➤  Correlate  ➤  Match.

2 Select one or more images to scale and rotate by clicking the image frames,

then press Enter.

3 Specify the first source point on the selected image.

NOTE You can select a point on the image frame by using object snaps, or
you can select points on specific raster entities by using raster snaps.

4 Specify the destination point where you want the first source point to

move to.

5 Specify the second source point on the selected image.

6 Specify the destination point where you want the second source point

to move to.
