Transparent toolbar color

I have created a dll addin for Solidworks 2004

I have implemented a toolbar and six buttons using AddToolbar3 and
AddToolbarCommand2.

I am able to add the toolbar ok with the large and small button
bitmaps

My button images do not fill the entire area of the button and I have
not been able to work out how to make the button backgrounds
transparent.

This is an issue, because not all computers have the same toolbar
background color. So no matter which variaton of grey I use, it will
not look good on all computers.

Is there a way of either specifying which color is transparent or a
different way of creating the buttons/images

Thanks in advance

The API documentation for AddToolbar4, which loads bitmaps from file instead
of from a resource, states that:

"The bitmap images should contain the bitmaps for each of the buttons
(including separators) in the toolbar as a single bitmap. For a small
bitmap, the image for each button must be 16x15; for a large bitmap, it must
be 22x22. The bitmaps should use a 16-color palette. Use gray (RGB 192, 192,
192) for transparent areas in your bitmap."



AddToolbar4 replaces gray (RGB 192, 192, 192) with the actual toolbar
background color. Maybe AddToolbar3 is the same? If you don't need your
addin to work prior to SolidWorks 2004, then you could use AddToolbar4,
which works OK for me.



I also found out from SolidWorks API support that, in SolidWorks 2005,
AddToolbar4 supports both 16-color palette and 256-color palette, which is
good for XP-style toolbars.

Is there a way of either specifying which color is transparent or a

"Invisible" background color is RGB 192, 192, 192
