Use this dialog box to correlate an image within the drawing when you insert it.
The Source tab displays correlation information from the selected correlation source. The Insertion tab shows how these settings apply to the current drawing.
Select a correlation source for the image. If a resource or world file exists for the image, it is in this list.
View the insertion point (X, Y, and Z coordinates) for the lower-left corner of the image frame. On the Source tab, this information is in the units specified in the Units area at the bottom of the tab. On the Insertion tab, this information is in current drawing units.
Enter the amount of rotation in current drawing angle units for the image. This value uses the lower-left corner as the base point.
Enter a scale factor for the image. A scale factor greater than 1 enlarges the image. For example, to make the image twice as large, enter 2.
Enter the dots (or pixels) per unit for the image.
Select the units for the insertion point and density. For example, if your image was scanned at 300 dpi, select Inches.
Apply your changes.
Click Pick (on the Insertion tab) to draw a frame for the image. For more information, see To Adjust the Image Frame During Insertion.
View the current color for the image frame and for the foreground of a bitonal image. Usually, this is the current AutoCAD Map 3D toolset color. However, when you insert a bitonal image, AutoCAD Map 3D toolset first looks for the foreground color in the image header file or in a resource file. If it cannot find the color information, then the foreground color defaults to the current AutoCAD Map 3D toolset color. To change the color, click Select (on the Insertion tab).
