Study the attached XAR file to see how the object is cut around the orange shape to exclude the orange shape from the color change.

if you are dealing with bitmaps and want to slice and dice, I would suggest making sure you feather the slice a bit so it'll match and not be so obvious where the slice is...

See attached example...

Hi Prince of OT quips ....

I'm not even sure what colour it is.

Oh wow....

A Real VW chameleon. I had own read about those. I heard that the paint job costs more than the whole car...

The only problem I heard was that they used tempra paint...

If you use the XPE utility or any photo editor with Photoshop plug-in abilities, don't miss the free Virtual Photographer, http://www.optikvervelabs.com/default.asp

Many color and B&W effects, plus extra effects to download. They're not your usual filter effects - many buttons and sliders to create different kinds of virtual photo paper, film and film speeds (grain), softness, halo, etc.

Interesting filters, DGehman. Thanks for posting the link.

I don't think we have answered the question.

You have to create two versions, a color version and a black and white version.

Create a vector shape over the object you want to change using Xara's vector drawing tools.

Use a Combine Shapes > Intersect Shapes or Apply a ClipView to mask the object that changes. See the second half of Dropping Out the Background in Workbook 36. The first part of the article covers a different method that is not what you want.

This tutorial does not quite do what you are asking how to do but the basic idea of how to create a mask is covered in some detail.

Remi's solution at the top of this page answers the question without creating two copies of the graphic???

Yes, you are correct since Xara retains the entire image even if you mask it. So you can edit the masked portion only and leave the other part of the image as is. And in 3.2 you can double click on a masked shape to open the designated bitmap editor.
