Image Tranparency in DVD-A

DataMeister wrote on 2/9/2004, 11:22 AM

The complaint came up in another thread that DVD-A didn't support image transparency.

I posted this in that thread, but I wanted to make a more obvious thread.

I've had perfect tranparency sucess with the PNG-24 format from Photoshop 7 using the "Save for Web" and checking the use transparency box.

Works perfectly. If only web browsers would work this well also.

I hope this helps.

I do my graphic work in Macromedia Fireworks MX 2004 (awesome pgm). It's native file format (with layers and all) is PNG. I created a graphic menu bar that overlays video from DVD-A that plays underneath it. The graphic throws shadows on to the transparent payne (which shows the video in DVDA). The shadows, of course, gradient to transparency in the PNG.

IN DVDA I just open the PNG file up and bingo it looks like the shadow of the menu is on top of the video in DVDA. Transperancy intact.

I'm not an expert in PNG but instead of Save for Web in Photoshop why don't you just try Save As and save it as a PNG.

Again I have not tried to work with transparent graphics in DVDa other than what I just tried but to me it works.

good luck

I like the idea you can add a shadow. How does this affect the
menu button when highlighted?

Are you writing the XML for the theme or using the theme editor from
C&M Software?

I would like to have a highlight shape over moving video
an example is the diamond ring in Stuart Little 2 DVD.

So far I haven't created any themes. Pain in the ass I say. I just layout as much as I can in Fireworks and then just add thumbnails/menu buttons etc.

BTW the graphic component throwing the shadow was not near a menu button. Not being able to create or control the button mask is a bummer.
