AndyColmes	Posted - Jan 04 2012 : 07:50:25 I would like to apply or change Brightness/Saturation in an image but only specified in a Selection. How can I achieve this? Thanks.

w2m	Posted - Jan 06 2012 : 14:37:32 Brightness can assume values from -100 to 512. Contrast can assume values from -100 to 100. Saturation can assume values from 0 to 512. William Miller
AndyColmes	Posted - Jan 06 2012 : 07:39:10 Thanks Fabrizio. It looks like adjustments are confined to a selection if there is one, if not it affects the whole image. What the recommended limits (min/max) for the Brightness and Contrast values?
fab	Posted - Jan 04 2012 : 09:48:34 Let the user to select a region (in this case a rectangle, but other shapes are available), with: ImageEnView1.MouseInteract := [miSelect]; Then change brightness/saturation, for example (other ways are available), with: ImageEnView1.Proc.AdjustBrightnessContrastSaturation(....); You can also select a region in-code. Example: ImageEnView1.Select(x1, y1, x2, y2); ImageEnView1.Proc.AdjustBrightnessContrastSaturation(...); About Select usage look also TImageEnView.SelectionBase.
