[WiX-users] Problems with custom bitmaps with wixUI

[Anthony Wieser]

I've been tearing my hair out trying to figure out why my bitmaps for my
dialog are getting a set of grid lines drawn across them.

I've finally got my install working with the latest build 3.0.2716.0 after
changing things to match the new methods, but still have the same problem
with the bitmaps.

I've added this as a bug (1684217), but on reading it looks like I should
have brought it up here first, so sorry if I got the protocol wrong. I'm
new to this open source stuff.

Any ideas how I can avoid this? I'm including the files thus:
<WixVariable Id="WixUILicenseRtf" Value="license.rtf" />
<WixVariable Id="WixUIBannerBmp" Value="bitmaps\banner.bmp" />
<WixVariable Id="WixUIDialogBmp" Value="bitmaps\dialog.bmp" />

I think this happens when your bitmaps are being squished a little bit.

Thanks for that. When I shrunk the bitmap drastically (to 450 pixels wide)
it went away.

I checked with SPY++, and the bitmap is 493 pixels wide (at least on my
Vista system, the way it's set up at the moment).

As the dialogs are specified in dialog units, what is the recommendation for
sizing bitmaps? Build something that can be stretched without much
distortion?

That's normal for XP too and that's what's in WiX.chm.

That's about your only choice. Bitmaps don't scale well and
unfortunately, there's no way to "lock" the dialogs.

I guess that's the problem. I started out with the tutorial pointed to by wix.sourceforge.net
http://www.tramontana.co.hu/wix/lesson2.php

and the values on that page are different.

dialog are getting a set of grid lines drawn across them.

As Rob mentioned, it's an artifact of resizing. WiX.chm has a topic that
lists the sizes of the bitmaps for default Windows XP themes but note
that users are free to choose different font sizes that change the size
of the dialogs and therefore the bitmaps.
