You can set the transparencyColor of a Picture control to the colour you want to make transparent. Im am unsure whether JADE fully supports the alpha channel in png files.

Is there a way to make a image on a jademask transparent?

I've made a toolbar with flat images using a jademask, the only problem is that the background colour of the buttons are fixed and it looks weird when the user is using a different colour scheme (or running a different version of windows).

Here's 2 alternate options:

1) Try making the image you're using an .ico file rather than a .png or ..bmp and set the areas of your icon transparent where appropriate and then the areas of your icon that are transparent will show the appropriate backColor for that JadeMask control.

2) Set the transparentColor for your JadeMask control to an appropriate colour that you use for flood fill on all your images for a given JadeMask control. You need to make sure that the colour you choose does not conflict with a colour already in use on any of the images your are using for a given JadeMask control.

As this property is not visible as a design time property on the JadeMask control, you either need to set it programmatically or you need to subclass the JadeMask control and make the transparentColor property visible as a design time property on your subclass.

I'm not sure why the JadeMask control doesn't have transparentColor as a visible design time property as nothing seems to break when you use this either programatically or by way of a subclassed control?

Hope that helps,
Pat.
