I found the online docs for this and noted the discussion of the type.
Is this the correct code for retrieving a generic App icon and creating a 22x22 icon that supports the @1 and @2 sizes when the HiDPI is on?
Dim iconImage As NSImageMBS
Dim iconPic As Picture
iconImage = NSWorkspaceMBS.iconForFileType("app")
iconPic = iconImage.CopyPictureWithMask
iconPic.VerticalResolution = 144
iconPic.HorizontalResolution = 144
GenericApp = iconPic
Or - is this an equivalent?
Dim i As New NSImageMBS
i = NSWorkspaceMBS.iconForFileType("fcpbundle")
Me.RowPicture(Me.LastIndex) = i.CopyPictureWithMask.ScaleImageAndMaskMBS(22, 22, True)
Both seem to work.
