Anyone know how to save multiple images of different bit depths to a single TIFF file from Icon? The reason I want to do this is because I want to create icons that show up in color on color systems and grayscale on grayscale systems. Now, I know this happens by default, but I want to hand-tune my grayscale bitmaps, which means including two icons in every file. The NXImage object is keen enough to display the correct depth bitmap if you have multiple bitmaps in a single file, but the problem is getting them there. I've done it by hand (with a little program I wrote) but I'm looking for a nice way to do it. And, since Icon seems to have a zillion features no one has figured out, I thought I'd ask the net. BTW, I tried defining multiple frames using Icon's Animate menu, but I can't get them to be different bit depths. -william shipley PS: For an example of a color/grayscale icon, look at Icon's icon. On grayscale machines the pencil is drawing ltgray, dkgray, and black dots, whereas on color machines it is drawing a sort of rainbow. (If there weren't two images enclosed, the icon would show up on grayscale machines with dithering on the dots.)

Editing multiple images in a single TIFF is not among Icon's many features. However, the command line program "tiffutil" will do what you want: tiffutil -cat FooColor.tiff FooMonochrome.tiff -out Foo.tiff Ali, Ali_Ozer@NeXT.com
