- A similar post in .apps resulted in one request for a summary,
- and one very partial answer. Maybe the thread I appended my
- questions to was already dying. Anyway, perhaps someone here
- is willing to do better...
-
-
- When editing icons, I find that it is possible to save
- them in any of a number of different formats, and that
- many combinations of resolution and number of colors are
- possible.
-
- I tried to learn about these formats in all of the online help,
- under every name I could think of. No dice. Can't find anything
- in the FAQ or by lurking in these newsgroups. If you can help,
- please answer:
-
- 1) If there is more than one format stored, which one will be
- used in a given situation? (screen resolution/driver, etc.)
-
- 2) I see that the icons appear to be about the same size regardless
- of the size of bitmap which is stored. How is the scaling
- done? (e.g., if I make a 64x64 icon, and display it on a
- screen where it covers only 20x20 pixels, does it average
- color values? throw pixels away? what?)
-
- 3) There is the option of storing the icon in (pardon my faulty
- memory of the terms) forms such as 1.2, 2.0 and 2.0 packed.
- a) is 2.0 incompatible with 1.2 systems?
- b) is 2.0 better than 1.2 for 2.0 systems?
- c) what is "2.0 packed", and why doesn't that button work?
-
- 4) It seems that icons can be stored in files like "myicon.ico"
- or in some other way (as part of the extended attributes?).
- how does this work? I'd just like to know what's going on.
-
- 5) Anything else I should have asked.
-
- I'll post a summary if it seems worthwhile, otherwise I'll just
- email to those who request it.
-
- Thanks,
