To Set the New Image Defaults

1. On the ribbon, click Raster Tools tab Insert & Write panel Dialog box launcher ().

   The Raster Design Options dialog box is displayed.

2. Click the New Image tab.
3. To change the default physical width of the image in pixels, enter a value in the Width box in the Default Image Properties section.
4. To change the default physical height of the image in pixels, enter a value in the Height box.
5. Type a default density (or resolution) for new images in the Density box.

   This defines both the horizontal and vertical density.

   Note: You should set this value to the density at which your images are scanned.
6. In the Default Color Type section, click a color type for the new image:
   • Bitonal (1-bit), with two colors.
   • Grayscale (8-bit), with 256 shades of gray.
   • Indexed Color (8-bit), with 256 paletted colors.
   • True Color (32-bit), with up to 16.7 million colors.
   Note: Selecting True Color uses more system resources.
7. If you want the New Image dialog box to appear when you create a new image, select Show New Image Dialog.
   Note: If this check box is not selected, AutoCAD Raster Design toolset will default to the command line interface when you create a new image.
8. Click OK to accept the changes.
