If an image does not contain location information, you can specify its insertion point and rotation so the image is inserted correctly in relation to other data.
To specify an image insertion point
- In the
Display Manager
, click
. - In the Data Connect window, select Add Raster Image or Surface Connection in the Data Connections By Provider list.
- Under Connection Name, type a name for this connection.
- Under Source File Or Folder, click the folder icon and browse to the folder than contains your image. Click Connect.
- Select the image to insert and click Add To Map.
- In the Image Insertion dialog box specify where to insert the image. You can enter X,Y coordinates for the image, or manually specify the insertion point in the drawing. Each option is described below.
To insert the image manually
- In the Image Insertion dialog box, on the Insertion tab, click Pick.
- Pick the base point for the frame.
You can also type coordinates at the command prompt.
- Type a rotation angle or pick a point to define the rotation angle.
Rotation is in degrees or in the units set by the AUNITS variable. The image is rotated around the insertion point.
- Pick the second corner point to define the size of the frame.
The Image Insertion dialog box displays the new coordinates, rotation, and scale.
- Click OK to insert the image into the specified frame.
To enter the coordinates for the image insertion point
- Specify the insertion point for the lower-left corner of the image frame.
The insertion point values on the Source tab use the unit specified at the bottom of the Source tab. The insertion point values on the Insertion tab are translated to the current drawing unit.
- Specify the rotation.
Use current drawing angle units. This value uses the lower-left corner as the base point.
- Specify the scale.
If the image you insert contains correlation information, the image is inserted at the scale specified by that information. Otherwise, the image is inserted at a scale factor of 1 image unit of measurement to 1 unit of measurement.
A scale factor greater than 1 enlarges the image, while a scale factor less than 1 makes the image smaller. For example, to make the image twice as large, type 2 in the Scale box.
You can change the scale to align the image with the vector geometry in the drawing. For example, if your raster image has a scale of 1 inch equals 50 feet or 1:600, and your drawing has a scale of 1 unit equals 1 inch, enter 600 as the scale.
- Specify the units for insertion point and density.
For bitmaps, the density unit used in the image may be in dots per inch. For satellite photos, the density may be in miles. This unit is also used for the insertion point.
For example, if your image was scanned at 300 dpi, then select Inches as the unit.
