Ppi in preflight... what's the fraction mean?

Most of the time in preflighting pdfs we get perfectly readable results on resolution such as 300 ppi, but once in a while a pdf gives results for specific images or slices of images with an unfathomable number like 6826.0864/13.186 ppi. Obviously there's a problem with the resolution, but I'm not sure what to make of that number or how to correctly explain to the client what's wrong with the file.

Bump. I don't suppose anyone has any ideas on this? It seems the meaning of those numbers should be documented somewhere, but I haven't been able to track it down.

What does the "S" mean in reference to lenses? EF-S vs EF lens?

I have both a digital camera, the 60D, and recently acquired an EOS 1N 35mm film camera. I have bought lenses for my 60D but not the 1N film camera....was told that my 18-55mm lens for my 60D would not be interchangeable with the 1N? So, EF-S vs EF lens, what is the S and what does it indicate? What does the "S" mean in reference to lenses? EF-S vs EF lens?
Thanks.....I am just getting started in photography and do not know all the different terms....
James

In the simlpest of terms think of the S as standing for SMALL sensor. The sensor in crop bodies is much smaller in physical size than the area your film camera needs covering with when the shutter opens. An EF S lens won't allow light to cover the full area in the film or FF body. This allows smaller & cheaper lenses but at the expense of limiting their use.

What is the exact mean of classname.class.

what is the exact mean of classname.class. what situations it will be use ful . how to use . give me one example .

Each class, interface, or enum loaded into the JVM has an associated Class object. This contains a lot of information about the class in question, including lists of fields and methods. <classname>.class gives you a reference to the Class object of the class mentioned.
See the java.lang.Class javadocs for all the things you can do with a Class object.
For example:
theImage = new ImageIcon(MainClass.class.getResource("item.png"));to retrieve an image file from the directory containing the MainClass class file.

HT1535 what does the cloud mean for my movies

For my ipad, I have a few movies I want on it. Most of my movies have a cloud in the corner and I do not want them on my ipad. What does the cloud mean?

Go to Settings>iTunes and App Store>Show All>Videos>Off. The movies with the cloud icon are movies in the cloud and they should disappear when you do what I posted.

Greetings,
Hm. I've never seen that in iCal. In some other Applications the tilde "~" indicates a restore point or a before / after for a file. My guess is there is a broken cache file in iCal.
Try:
Go to Apple Menu > System Preferences > Language & Text > Formats > Region. Region should be set to the country of your choice. Do not have it set to "Custom" as this can have unexpected results in the iCal window.
If that doesn't resolve the issue:
1. First make an iCal backup: Click on each calendar on the left hand side of iCal one at a time highlighting it's name and then going to File Export > Export and saving the resulting calendar file to a logical location for safekeeping.
2. Go to iCal > Quit iCal
3. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
--- NOTE: To get to "Home > Library" in Lion: Click anywhere on the desktop and then click on the "Go" menu at the top of the computer screen while holding down the "option" key on the keyboard. You will see "Library" in the menu.
4. Launch iCal and test.
If the issue persists:
1. Go to iCal > Quit iCal
2. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
--- NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
3. Launch iCal and test.
Hope that helps.

What is the CellValue mean in SDO_GEOR_GRAYSCALE

hi!
What is the CellValue mean in SDO_GEOR_GRAYSCALE and SDO_GEOR_COLORMAP? If the Raster data is continuous, how to enum them when use the SetGrayScale function?

I don't have my doc with me, but, for instance, if your data is 8 bit unsigned then you would specify 0 to 255 for cell values, and map them to the grayscale. The requirement is that cell values be entered in ascending order, and gray scale values be between 0 and 255. There are two number arrays you fill in, one has the cell values (the actual numbers stored in the cells), the other has the gray scale values they map to.
Colormap works in a similar fashion, where you specify a cell value and r/g/b/opacity using five number arrays.

I want to move my photos from iPhoto to Time Capsule to make space on my computer. What's the best means of doing this?

I want to move my photos from iPhoto to Time Capsule to make space on my computer. What's the best means of doing this?

Please do not do this.
The Time Capsule was designed for your backups.....not as an everyday hard drive. Access to the Time Capsule is slow.
If there is any loss of connection between iPhoto and the iPhoto library when you are reading or writing, the entire iPhoto library is easily corrupted.
The chances of corruption are even more likely if you are using wireless on the computer.
And....even if you decide to risk this....if you move your "original" iPhoto library to the Time Capsule.....how will you make backups of the library?
The only copy of the library will be on the Time Capsule....you have no backups.....when, not if, the Time Capsule has a problem.
Simply stated, I would never do this with any important data that you cannot afford to lose. Please post in the iPhoto support area if you need to confirm this.

If you do want an idea of how to move your iPhoto library correctly, post back and we can help.

If there is no SIM card, insert one from the carrier to whom the device is locked.
As for unlocking the device, only the carrier to whom it is locked can unlock it.

IMac with Lion. I have an icon on the dock for Fluenz software but it has a white circle around it with a white slash through it (like the international "no" sign). What does the circle mean?

I have an iMac using Lion. I have an icon on the dock for Fluenz software but it has a white circle around it with a white slash through it (like the international "no" sign). What does the circle mean? The Fluenz software seems to work ok.

Checkout the software vendor's website for updates:

Your only other option is to boot from an OS X 10.6 system.
