The following actions are available when editing a color curve:
◼Left-click outside the curve to add a new curve point
◼Left-click on a curve point to drag it to a new position
◼Right-click on a curve point to remove it

Note:
◼Color curve editing is also available to the user in the Image Processing dialog
◼The pixel format of the image should be ie24RGB

Demo

Example

// Display a form that allows adjustment of the colors of an image

// Assign our image to the color component
dlgCurve2.IEColorCurve1.AssignSource( ImageEnView1.IEBitmap );

// Show form, and if user clicks OK assign that curve to our image
if dlgCurve2.ShowModal = mrOK then
begin
  dlgCurve2.IEColorCurve1.ApplyCurve( ImageEnView1.IEBitmap );
  ImageEnView1.Update();
