How do you write an image threshold to a file

Hi, I use IMAQ threshold to threshold an RGB image. How do I write this image to a file? Whenever I use the IMAQ Write JPG or Write PNG vI and try to view the file with the windows image viewer all I see is a black image. Does anyone know how to save a binary image?

If you cast it to an eight bit image and save it as a BMP or JPEG does it show up correctly? If so the problem probably lies in the fact that a 16-bit image in LabVIEW is signed, while third party viewers usually assume that it is unsigned. So rather than pixel values going from -32766 to 32767, they go from 0 to 65536. There are example programs on ni.com to get around this. One is called "Mapping a 16-bit Image to an 8-bit Image," another is called "Bit Shift an IMAQ Vision 12-bit Image and Resave for External Viewer." If you search for these titles on the ni.com search bar, you should be able to find them.

In Lists - How do you write an Image and Attributes in the defined fields?

I have tried #IMAGE_PREFIX#load_ascii.gif with no results..
then tried /i/load_ascii.gif
then tried load_ascii.gif
Can you give me an example or something else is wrong because just a diamond bullet is showing up? Trying to emulate the Run icon in the Application Developer's home Page.. or is this the wrong way of doing it?

Using a list, I want to apply an image from the /i/ folder. In the List Entry Area under Label and Sequence I tried several syntax varations with no luck in the Image and Image Attributes Fields. With the List Entry Label I want to display and Icon (Image) they can click on with the List Entry Label below the image.. I've tried #IMAGE_PREFIX#load_ascii.gif with no results..

How do you write a class to return a file?

So I've read http://java.sun.com/docs/books/tutorial/uiswing/components/filechooser.html
But I still do not know how to pass a file to a calling method of another class. How does the FileChooser class retrun the file. Please help.

You mean something like this?
import java.io.File;
public class FileTest {
     public File getFile(String path) {
     //Example path = "C:\\path\\to\\file.txt"
          return new File(path);
}

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

How do you add an image in the signature

Hi,
How do you add an image to the signature area.
The Insert/edit image is not available when in My Settings | Personnel Info | Signature
Regards
Ray Farmer

You need to link the image. See the example for the Canada flag below.
<img src="http://forums.ni.com/ni/attachments/ni/130/6908/1/Canada-small.PNG" border=0>
Replace with the image you like. This goes into the signature box within the profile tab of the personal settings.

How can you upload an image to MYSQL using php?

Ok this is a joint thread with one of my other ones because no one else was posting on it, so I did not get what I needed, so, How can you upload an image to mysql so when some one logs on to my site, they see or can upload there own avatar, now there are loads of problems with this, 1) many people don't know how, 2) It's not every day you try to encode a image into mysql, 3) Letting people upload images into mysql can cause traffic problem with people trying to log in. So that's it.

Uploading images into MySQL is a bad idea, for more reasons than you mention. You should store the images in a directory on the server instead. But if you want to learn the hard way, here is the method:
The mysql data type must be blob.
The form enctype must be multipart, like this: enctype="multipart/form-data"
The form input field myst be type file, like this: <input type="file" name="upload"/>
Here is example code that prepares the variable $photodata to be inserted into the database.
$uploadfile = $_FILES['upload']['tmp_name'];
$photoname = $_FILES['upload']['name'];
$uploadtype = $_FILES['upload']['type'];
if ($uploadfile != "") {
$tempfile = fopen($uploadfile, 'rb');
$filesize=filesize($uploadfile);
$width=getimagesize($uploadfile);
$widthx=$width[0];
$heightx=$width[1];
if (($widthx > 102) or (heightx > 135)){
$image_too_big = " but the image size was too large and was not submitted.";
} else {
$photodata = fread($tempfile, filesize($uploadfile));
$photodata = addslashes($photodata);

How can you add an image in Mail without being an attachment?

How can you add an image in Mail without being an attachment?
In otherwords I'd like to put my logo in the email not as an attachment but as an image.
Is there a simpel solution to this problem?

You don't.
It's not possible. The e-mail protocol is designed for text; anything else has to go as an attachment.
Different mail clients (such as Mail.app, the mail client bundled with Mac OS X) may have different ways of handling such attachments, but they are still attachments. Each mail client has its own rules and methods, so one may display a picture as if it were in the body of the message, but another client may do something completely different.
A way of faking it is to format your message in HTML (which is a kind of text). The image is hosted on a remote server, not added to the message; instead, you include a link to it in the body of the message, as you would when building a web page. (This is also what the two tips helpfully provided by X423424X do, except that the link to the image is added in the signature, rather than the body of the message.) What exactly happens to it is, again, at the discretion of the mail client. In my case, for instance, displaying images in HTML messages is turned off, and will stay resolutely off.

The same way you put them on the phone. Connect the phone to iTunes on your computer, click on the name of the iPhone, then the Photo tab. Uncheck the albums you don't want on the phone and click Sync.

Thanks, Bill

You can use;
<ITEM> := Get_Item_Property(<ITEM>,DATABASE_VALUE);
Or you will have to write a pre-text-item trigger;
PRE-TEXT-ITEM:
:CTRL.CURRENT_VAL := :<BLOCK>.<ITEM>
MENU (PL/SQL):
:<BLOCK>.<ITEM> := :CTRL.CURRENT_VAL;
You may also want to set the item property back to ITEM_IS_VALID so that item validation does not fire again.

In another thread I posted a suggestion to try when the iPhoto app in the Application folder will not work:
after upgrading the OS, iPhotos (and Aperture for that matter) should still be in the Applications folder...
And running well in 10.10.3.
If it stops running in a next "update" do not throw it away: most apps will continue running as follows:
In the Applications folder "rightclick" (CTL+click) the iPhoto app, then "show package contents", then click the MacOs folder open: you see the real app (dark grey), rightclick this and choose "make alias", an alias is made, move this alias to the Applications folder and use it to run iPhoto.
Same for Aperture.
In older OS this survived several upgrades....
