Brightness

This command enables you to change the brightness of an image.

\imgedit Brightness@

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:

$image\ebx_2097330596.gif$

When the value is greater than zero, the image becomes lighter.

$image\ebx_-1130499371.gif$

When the value is lower than zero, the image becomes darker.

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 Factor potentiometer enables you to lighten or darken the image. The default value is zero (at the center of the potentiometer). Move the cursor to the left (0 to -1000) to darken the image or to the right (0 to 1000) to lighten it.

You can also enter a value (between -1000 to 1000) 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.
