Of course I am not in tpe position to comment on what Apple REALLY intends to do, but this is what they said in the preliminary developer notes for Finder 7.0 published in april last year. In previous versions of the Finder, the only kind of icon that could be included in a bundle was a standard 32-by-32 two-color icon. In Finder 7.0, it is also possible to include small and color icons in a file's bundle. These icons should look like the 'ICN#' resource. Moreover, any additional icons must have the same resource ID as the 'ICN#' resource. The resource types for these additional icons are as follows: o A 'SICN' resource contains a small (16-by-16-bit) two-color icon together with an icon mask. o An 'ics4' resource contains the data for a small icon for which there are 4 bits of color data. This resource uses the 4-bit system color look-up table (CLUT) and the icon mask contained in the 'SICN' resource. o An 'ics8' resource contains the data for a small icon for which there are 8 bits of color data. This resource uses the 8-bit system color look-up table (CLUT) and the icon mask contained in the 'SICN' resource. o An 'icl4' resource contains the data for a large (32-by 32-bit) icon for which there are 4 bits of color data. This resource uses the 4-bit system color look-up table (CLUT) and the icon mask contained in the 'ICN#' resource. o An 'icl8' resource contains the data for a large (32-by 32-bit) icon for which there are 8 bits of color data. This resource uses the 8-bit system color look-up table (CLUT) and the icon mask contained in the 'ICN#' resource. All of the color icons use one of the standard system color tables to define the colors. The two main advantages of usinf a standard color table are reduced resource requirements and reduced color arbitration. When a color icon is selected, Finder 7.0 displays the icon using a special CLUT in which each color is darker than the corresponding color in the standard CLUT. This makes selected color icons look very much like selected icons in previous versions of the Finder. So there you are... This will be the way it works in System 7.0 and developers should design their own color icons to put in their applications. +-------------------------+--------------------------------+------------------+ | Sven Axelsson | d83_sven_a@tekno.chalmers.se | DISCLAIMER: | | dep:t of Linguistics | (^^ best ^^) | | | univ. of Gothenburg | dlv_sa@hum.gu.se | This is not | | SWEDEN | usdsa@seguc21.bitnet | a disclaimer. | +-------------------------+--------------------------------+-------------------

How did I notice? Because after I unstuffed them, the color icons appeared on my desktop... once. After I restarted my Mac, they reverted to the black-and-white icons. Does anybody know why this occurs? I'm running System 6.0.4 on a Mac II. * * ** Scott Robert Anderson gatech!emoryu1!phssra * * * ** phssra@unix.cc.emory.edu phssra@emoryu1.bitnet * * * * * ** * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
