Posterize

This command enables you to create a "poster" effect by a reduction in the number of colors and "flattening" of the image.

The system asks you to indicate an image to be modified. After you confirm your choice of image, ARC+ opens a dialog box that helps you control and view the modification:

$image\ebx_1786973799.gif$

This dialog box contains two "Before-After" windows for a dynamic preview of the modification.

The $image\ebx_2025542677.gif$ button enables you to view the entire image; the $image\ebx_-896310760.gif$ button enables you to view a detail of the image in actual pixel size.

The levels per color plane potentiometer enables you to enter a value between 2 and 64. The flattening effect becomes more significant with the reduction in the number of levels.

You can also enter a value in the numerical range located to the left of the potentiometer.

Click Ok to modify the image or click Cancel to cancel the modification and exit the dialog box.

Before applying the modification, the system asks you to indicate a modification setting: apply the change only to the selected image (frame) or to the indicated image (frame) and all its copies.
