How do I store the values in the @D array in the below mentioned VI? Only the last row in the Array is populated with values from the image.

Hello Guys,
I am trying to build a sinogram from 180 projection images and I am not able to store the summed values into the array as it is moving the values and then populating all the rows except for the last with ZERO.
Thanks in advance.

Your loop runs only three times, so all you can possibly populate is 3 rows.
Typically, you would initialize a shift register with the initialized array, then use replace array subset, feeding the modified array back into the shift register. However, in this case you could just autoindex the 1D array at the output tunnel to build the resulting 2D array.
Sorry, I am not familiar with sinograms. Do you have a link describing the algorithm?

How can i store the data from the list to MS-Access?

Hi all,
We all know that from alv it is possible to export data to Ms-excel or word or text file. Can anyone tell me how can i store the data from alv or reports to Ms-Access?
Thanks in Advance,
Abhijit

Hi,
If you want that without code, i suppose there is a option in MS-Access to import data from Excel, so you have to first export to excel and then import to Access.
If you want to code it yourself then have a look at FM TABLE_EXPORT_TO_MSACCESS, as said in Exporting Data from R/3 to MS ACCESS
You can also see the search results in SCN for [export data to MS-Access (45 Results)|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=exportdatato+MS-Access&cat=sdn_all].

How to store the images in Oracle?

Hi,
I am a new developer, trying to find out how to store the images in Oracle. Is there anyway that I can store the images in Oracle and insert them into my html file?
Thanks!
Sarah

There is a simple image example available from OTN.
From the OTN main page, go to Products --> interMedia --> Sample Code. The name of the example is "Load rich media content with a browser."
This example loads and retrieves an image from an Oracle8i database through a web page using the Oracle interMedia Web Agent.
Hope this helps.

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

Can anybody help me how to do that?

Hi Kasturi,
> not accepting the points
It worked on this and on one other thread, but this is still open: How to upload the image
> want upload the images from the client side machine
> to KM
In the thread I just referred to, I already provided information about the HTMLB upload control. With this at hand, you'll get the file from the client to the server.
At server side, get an ICollection instance where you want to store the file and create the corresponding resource. See https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/javadocs/nw04/sp12/knowledge management/com/sapportals/wcm/repository/icollection.html#createresource(java.lang.String,%20com.sapportals.wcm.repository.IPropertyMap,%20com.sapportals.wcm.util.content.IContent)

Hi Sam,
You cannot do this directly as exclusion, but you can include all other values, even as ranges and thus exclude the particular value, else you can also try to do this by writing a routine.

Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store
If you want to back up the Photos only:
Export them using the File -> Export command.

How do I set the image size in PS touch to print to my Epson printer w ithout losing any of the picture. PS Touch appears to be showing pixels and not inches, how can I covert it toshow inches?

I am using PS Touch from my tablet . I am importinga photo from an SD card . When all editing is completed I then send it wireless from the tablet via Epson I print to the printer. It all works great except that part of the photo at each end is cut off and does not print. I am printing on 8.5 x11 paper.
How do I convert the image size in PSTouch frm pixels to inches?

Epson's iPrint has always been an oddball. It will always "zoom in" on an image to print even if you have the proper dimensions and resolution set for actual print size. I think other users have reported this, at least on Android.
You can't have PS Touch show inches instead of pixels at this time but you can use an online website to find out what you need to fit within a particular resolution. (Google "pixels to inches calculator".)

How can we get the image which is stored in clipboard by labview, is there any functions available like text from clip board

How can we get the image which is stored in clipboard by labview, i can get the text in clipboard by using invoke node directly.but i cannot get the image, is there any functions or vi available.(image is in Png format)

The Read from Clipboard method is, unfortunately, limited to text. If the clipboard contains an image then you need to use OS-specific functions calls. This is an example program for Windows. It's old, but it should still work.

How do you shuffle the image order when creating a new slideshow in apterture 3? i would like to do this automatically when creating a new slideshow. i see how you do it when you just play a slideshow.

how do you shuffle the image order when creating a new slideshow in apterture 3? i would like to do this automatically when creating a new slideshow. i see how you do it with presets when you just play a slideshow, but i don't see an option to randomly shuffle the slide order when you create a new slideshow. i know you can sort it by different fields, but i want it to be random. thanks.

If you want to rearrange images in random order you can try an AppleScript:
retrieve a list of selected images from Aperture
shuffe the list properly
create an album in Aperture and add the images from the list to the album (make sure that the album set to be orederd manually)
Here is a sample script that shuffles the selected images and displays them in random order in Full Screen Mode:
on removeItem(ims, i)
-- remove the item at position "i" from a list ims
          if ims is {} then return {}
          if (length of ims is 1) then return {}
          if i < 2 then return rest of ims
          if (i = length of ims) then return (items 1 thru (i - 1) of ims)
          if i > (length of ims) then return ims -- should be error?
          return (items 1 thru (i - 1) of ims) & (items (i + 1) thru (length of ims) of ims)
end removeItem
on shuffle_items(ims)
-- shuffle the items of the list "ims" randomly
          local numitems, ims_shuffled, nextrest, nextpick, i
          set numitems to length of ims
          if length of ims < 2 then return ims
          set ims_shuffled to {}
          set nextrest to ims
          repeat until nextrest is {}
                    set i to (random number (numitems - 1)) + 1
                    set nextpick to item i of nextrest
                    set beginning of ims_shuffled to nextpick
                    set numitems to numitems - 1
                    set nextrest to removeItem(nextrest, i)
          end repeat
          return ims_shuffled
end shuffle_items
on shuffleIms()
-- retrieve the selected images from Aperture
-- and display them in random order in full screen mode
          local imageSel, shuffled, i
          tell application "Aperture"
activate
                    set imageSel to (get selection)
                    set shuffled to my shuffle_items(imageSel)
                    set fullscreen to true
                    if imageSel is {} then error "Please select some images."
                    repeat with i from 1 to count of shuffled
                              reveal {item i of shuffled}
delay 3 -- chnage that to the time you want
                    end repeat
                    set fullscreen to false
                    return shuffled
          end tell
end shuffleIms
shuffleIms()
Some more code snippets to go from here:
To create an album:
                    tell library 1
                              if not (exists album "shuffledAlbum") then
make new album with properties {name:"shuffledAlbum", image version:shuffled}
                              end if
                    end tell
And to add the images from the shuffled list to the album:
                    repeat with i from 1 to count of shuffled
                              duplicate item i of shuffled to album "shuffledAlbum"
                    end repeat
