Image control with PNG support

[Dejan]

Hi,

I have an Excel application with all the forms/controls background
color set to ButtonFace (system color). I have a logo in a PNG format
(with background color transparent) that I need to put on the form. But
ImageControl does not support PNG and the other types (BMP; JPG) don't
support transparency.

What is a possible solution? Is there a control that supports PNG,
already embedded in Windows XP/Office 2003? I need to distribute the
application so I would prefer not to depend on third party libraries...

thanks very much

regards, dejan

The GIF format supports transparency which you can place on a form or in an
image control.

Thanks,

This is true but GIF supports only 256 colors, as somebody told me, and
my logo has more than 1000. Besides, GIF does not support antialiasing
that PNG does....

Do you really need >256 colours and anti aliasing for a logo ?
Surely it's not taking up half the userform ?

If you really need it though, maybe display in a webbrowser control.
Does the Rich Text Box support PNG images ?
Or find a custom Active X control on the Web.
