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
To insert the image manually
You can also type coordinates at the command prompt.
Rotation is in degrees or in the units set by the AUNITS variable. The image is rotated around the insertion point.
The Image Insertion dialog box displays the new coordinates, rotation, and scale.
To enter the coordinates for the image insertion point
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.
Use current drawing angle units. This value uses the lower-left corner as the base point.
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.
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.
