lol ...we're not talking photoshop here ...that's all data stored inside the TIFF from photoshop ...the actual TIFF doesn't contain transparency. If you took a layered TIFF and opened it in preview you would get a white background<br><br>
All I know is that if I import a stock TIFF into Keynote or Pages or whatever, its transparent. That sounds like it supports transparency to me. If you open a .png in Preview what color is its background?<br><br>
I'm sure you both would know the details more than I, but I only know what I see. <br><br>Here's an example file. (2.5 MB)<br><br>It comes from this program that lets you export as various file types:<br><br><br><br><br><br>Then if I import it directly, or paste it from Preview, on top and between objects in Keynote it looks like this. Notice that transparency is preserved and I can even have dropshadows fall on the objects underneath it.<br><br><br><br>Also, try this. If you have a file open in Photoshop with a transparent background, just copy it to the clipboard and open it with Command-N in Preview. Yep, sure enough, white background. Now copy that to the clipboard and paste into Keynote or Pages. The transparency is preserved. So Zwei, I don't see what that comment about having a white background when opening in Preview has to do with anything?<br><br>I don't know enough to argue with you about what the technical definition of "supporting transparency" is, but these TIFFs have transparent backgrounds whether they are in Preview, Photoshop, Keynote, Pages.... etc.<br><br>
Actually I exported it wrong at first, but here it is in Word (the biggest Turdmeister of all for graphics) imported and moved around on top of other objects or text.... transparent.<br><br><br><br><br>
