Structure icvo type blob is icon view options. Structure icvt type shor is icon view text label (filename) size.

The Finder seems to create these (at least on 10.4) even though it will do the right thing for window height with only an fwi0 around, perhaps this is because the stored height is weird when accounting for toolbars and status bars. If present, it overrides the height defined by the rect in fwi0. Structure fwvh type shor is Finder window vertical height. The next four bytes represent the view of the window, 'icnv' is icon view. The data is first four two-byte values representing the top, left, bottom, and right edges of the rect defining the content area of the window. Structure fwi0 type blob is Finder window information. DS_Store is documented on the mozilla wiki. Seems like most of the things we need for.

/tmp/test1734 is a folder I made with mkdir.

/tmp/test1607 is a folder which I have used SetFile on.

The best way to do this would is writing the file directly from the program, but we need to figure out how the file format works and what bits and bytes we need to set in order to accomplish the following: Then sleep for some seconds which makes Finder save the changes to the. Right now we use apple script to open up the finder, rearrange the icons and set the background. Should be fairly easy to implement in pure js. I would guess that this program really just sets some bits. We use the bless command to make sure that the Finder opens the image after mounting it. hdiutil is distributed with vanilla OS X so this is only needed for support of other platforms. We need to be able to create a dmg file from a folder, this shouldn't be too hard.

Using a pure js implementation here would be awesome just in it self since SetFile is distributed with Xcode.
