What\'s the deal with Graphic files in OSX?
« on: March 22, 2003, 03:57:00 PM »
The short time I had OSX running before the computer went on the fritz, I put a CD I had burned from an earlier time with a bunch of jpegs and tiffs etc,. on it in the PictureViewer format.
I had cut the suffix (jpeg) off of them.  

When I put the CD into the the G4 running OSX, the type looked strange on the CD files and of course as soon as I opened one Classic launched. Do I need to rename all those files and change the Creator codes for all of them if I want to be able to view them in OSX?
Were talkin a lot of graphics files here. Collected over years and years.

Gary, you should be able to select one of the files, (don't open it, just select it) and then click on File->Get info->Open with, and change the application to one in OS X - iPhoto, Preview or Photoshop 7 if you have it or Graphic Converter. Then click on "Change All" and all the files like this will now open with the selected application. There is also an "Open with" option under the File menu, which gives you the various options, but it only applies to the file you've selected. Handy if you want to open a particular file in a different app and don't have that application running already.

Thanks Paddy,

I just checked and I have 2.48 Gigs worth of these graphics files.

I wonder if  "Preview" has it's own creator code so I could batch convert them or is it's some UNIX thing. I don't know much of anything about UNIX. I picked up a book off the shelf at the bookstore today, opened it read a few paragraphs and put it back like it was raw meat.
Very foriegn to me and something I don't think I want to geek on.

It sounds like X did what it was supposed to do when you first tried to open these JPEG's. It recognized them as PictureViewer files and went to Classic which is where that app probably resides. Is this correct?

As for finding a 'Creator" code for Preview, I' m betting it doesn't have/use one. I don't think 'new' X programs use those codes anymore. I think they only create file name extensions. Apparently they can be longer than just 3 letters, also. But if you have set the System to not show those extensions, you will never normally see them. I would supoose that simply turning that option on, temporarily, would allow you to see the  ".extension' for Preview. But it sounds like you don't even need to do that, just follow Paddy's directions.

This 'feature' doesn't sound quite as bad as I once thought it was, but it seems it would still be easy for a human to get confused about what program will open a file (even if the Mac won't).

BTW, there are several good books more about X than UNIX that might be more what you need. The problem with these kinds of books is that they are so soon out of date!

If those files are on a CD, then they're READ only, so you can not assign a new creator code to those files.

You can however associate that file type to Preview (or any other application) using Paddy's suggestion.

Creator codes may still exist in OS X, it's now metadata and imbeded in the document and not the resourse fork.

Thanks kps,

Metadata.....Hummmmm!

I suppose I could copy them all back to my HDD and have them inbedded-hey. So I take it "ogle" lives only in OS9x and below.

I always liked the ogle Filetype.    

I've got Pouge and Robin William's book. They are both good books for OSX.
I was reading Bruce Frasiers Photoshop 7 book at the bookstore today, (it hasn't changed much since my version 5 book) except for a couple of things about OSX but not too much.

The "Preview" app in X will open most images Gary.

Fact is. I found out recently "Preview" will open images no matter where I have them stashed on the 'puter. Whether another partition,drive it doesn't matter.
You can save it anywhere your little heart desires also.
PictureViewers out of the {pun} picture with Jag.Unless we're talking classic.
Shame because I've always liked PV. Oh well.
Then of course there is options as Paddy stated etc etc blah blah.  

pssst ... don't even ask me what all those apps are all about,cus I haven't a clue.

Ah... *snicker**
So now you all get to do what one does in Windows... assign apps to files...  

Sorry, just kidding around... I could not resist, I'll shut my trap now...

I hope you mean while they are on the CD. This is true on a PC even when written to the HD. One of the most stupid things I think I can imagine, but there it is. Tell me UNIX/OS X is not that feeble minded, puleeze!

In my heart of hearts I really think Apple is going to come out with a different Operating System pretty soon if OSX doesn't make money.

If I were Apple I'd get rid of all the NexT people and hire as many of the people that are left from the old days and come up with something better. Easier to use and not based on UNIX.

Then MicroSoft can copy that too.  

Just my opinion.

You'll change your mind once you've been puttsin around in X for a while Gary S.

I was one of the 8.6. die hards remember. <gr>

9.2.2. is rock solid.
Jag is SOOoooooo pretty ...... have a hard time rebooting back into 9 now days.  

Although if I need to get something done fast and precise ... back to 9.2.2.!
Probably cus I'm used to the old die-hard OS.

Figure by the time I can run around in Jag barefooted without stubbing my toe the G5s will be out.

This is not just about UNIX, this is about further reaching issues.

Here's an excerpt from THIS article:

 
quote:
The situation for plain files is  somewhat less perfect. There are only two popular methods for representing  concrete types: HFS/HFS+ type/creator codes and filename extensions. Mac OS X  supports both, but Apple " strongly  encourages developers to use file extensions as alternative means for  identifying document types. " Apple's reasoning is that the Internet, the  new "lowest common denominator" of interoperability, does not support HFS-style  attributes and forks; it deals only in flat files. Where the overwhelming  majority of "flat file" volume formats (i.e. Windows/FAT, Unix/UFS) failed to  change Apple's thinking, the pervasive connectivity of the multi-million-node  Internet has succeeded.

On the other hand, Apple itself  provides a method for preserving HFS/HFS+ resource forks and meta-information  across flat file systems. When a file with HFS/HFS+ attributes and/or a resource  fork is copied or moved to a flat file system like UFS, the Mac OS X Finder  creates a hidden file containing the meta-information and the resource fork  data. When that file is copied or moved back to HFS/HFS+, those hidden files are  read and re-incorporated back into the file. So while Apple encourages the use  of file name extensions, it also provides a mechanism that allows the "old ways"  to continue functioning more or less transparently within Mac OS X.

Seems it may take me a while to understand.    

"Let's look at the simple example of a JPEG file. If it has an HFS/HFS+ creator code, it is opened with the creating application. But if it only has an HFS/HFS+ type code and/or the filename extensions ".jpg", then a list of applications that "claim" JPEG files must be constructed. Who gets to be on that list? Any application that declares itself as an "Editor" or "Viewer" of JPEG files? Just the "Editors"? Just the "Viewers"? What if both Editors and Viewers are available? Who "wins" in that situation? As I wrote earlier, this resolution process is unclear at this time."

I guess that has been solved by allowing various "new" applictions or packages such as "Preview" to open the files.
