Extract image form a buffer in a ring with labview

I use two buffers in a ring for an image acquisition in order to substract two images in real time.
After the buffer in the ring I didn't succeed to extract the image with the VI substract,in order to store the image in others buffers( error 14...)in order to realise the substract operation with the 1411 imaq acquisition grabber.
Could you help me to solve this problem.

I would use a buffer with more than two images. Ten to thirty images would work better. Keep the array of images that you generate when you are filling the ring buffer. During acquisition, you can use IMAQ status to find out what the last completed image buffer is. You can figure out the previous image easily by subtracting one and checking for wrap when it is -1. Index these images out of the image array and feed them into the IMAQ subtract vi along with an image allocated for the result. Display your results and continue to loop.

How can I extract images form other web pages with an applet?

Hello
I have a problem
Here is my code

Does anybody have an idea to solve the problem?

A scan from string function can be used as per the attachment. The double \ ('\\') is in the format string in order to interpret the '\' characters in your input string as literal characters and not special formatting.

Extract image and Features from the Catalog via JAVA API

Hello,
I would like to Extract image from the Catalog via JAVA API, Can anybody help on that? I also tried to extract the Features field form the Catalog but results in the error "Features field not found" Any ideas what could have wrong?
Many thanks,

Hello,
Can anybody tell me where i can find the latest JAVAAPI reference guide? I found the one for MDM 5.5 SP 1 but that also refers to the last parameter of the CatalogCache.Init as int and not string.
I looked up in service.sap.com/instguides -> SAP Netweaver -> Release 4 -> Installation and there only following 3 files are there for MDM 5.5 SP2
MDM 5.5 SP02 - Configuration Guide SAP MDM
MDM 5.5 SP02 - Installation Guide SAP MDM

White background of extracted image prints in pdf

Hi'ya
Using the "Extract" filter to crop a photo in Photoshop 7.0 allowed me to extract a person from a photo and it was saved as a .psd file.
In my InDesign 2.0.1 layout, the psd file looks great and as it was an extracted image, I can put things in the foreground or background for a layering effect.
I go to make a pdf and the pdf looks great on screen but when it comes to printing a white but invisible box prints around the psd file and blocks off items behind it.
HELP!

Did You export a pdf 1.3?
And what kind of printing are You talking about? Offset or some office inkjet?
Because in my experience the Acrobat preview (if Overprint Preview is active at least) represents the actual output very closely; and therefore I wonder if the printer or the RIP may be at fault.
But actually I think the problem might be better fit for the Acrobat forum as Photoshop seems not to be the cause of the problem.

Which is better? Extracting images from directories or from database?

Good day,
I would like to start a discussion on extracting image (binary data) from a relational database. Although some might say that extracting image from directories is a better approach, I m still sceptic on that implementation.
My argument towards this is based on the reasonings below:
1. Easier maintainence. - System Administrator can do backup from one place which is the database.
2. High level of security - can anyone tell me how easy it is to hack into a database server?
3. image is not dependent on file structure - no more worries about broken links because some one might mistakenly change the directory structure. If there needs to be a change, it will be handle efficiently by the database server.
The intention of my question is to find out :
1. Why is taking image from a directory folder which resides on the web server is better than using the same approach from the database?
2. How is this approach (taking image from directory) scalable if there is thousands of images and text that needs to be served?
If anybody would be kind enough to reply, I would be most grateful.
Thank You.
Regards
hatta

Databases are typically more oriented towards text and number content than binary content, I believe. If you carry images in the database you will need to run them through your code and through your java server before they are displayed. If they are held in a directory they will be called from hrefs in the produced page, which means that they are served by your static server. This is quicker because no processing of the image is required. It also means the Database has to handle massively less data. Depending on the database this should be far quicker to query.
It is worth noting that it is also quite difficult to actually change mime-types on a page to display a picture in the midst of HTML- the number of enquiries on these pages about this topic should be enough to illustrate this.
If you give over controls of all the image file handling to your java system (which I do when I write sites like the one you describe) then the actual program knows where to put the images and automatically adds them to the database. The system administrator never needs to touch them. If they want a backup they save the database and the website directory. The second of those should be a standard administrative task anyway, so there is not a huge difference there. The danger of someone accidentally changing the directory structure is no greater than the danger of someone accidentally dropping a database table- it can be minimised by making sure your administrators are competent. Directory structures can be changed back, dropped tables are gone.
The security claim is slightly negated because you still have to run a webserver. Every program you run on your server is vulnerable to attack but if you are serving web pages you will have a server program that is faster than a database for image handling. You are far more at risk from running FTP or Telnet on your server or (worst of all) trying to maintain IIS.
The images in directory structure is more scalable because very large databases are more likely to become unstable and carrying a 50k image in every image field rather than 2 bytes of text will make the database roughly 25000 times larger. I have already mentioned the difference in serving methods which stands in favour of recycling images. A static site will be faster than a dynamic site of equivalent size, so where you can, take advantage of that.

Referencing "image" form elements using Safari

I'm trying to write an Applescript which uses Safari's do JavaScript feature to reference the elements of forms in web pages. I've run into a puzzle in cases where the page designer chose to use an element of type "image" for form submission. It looks to me as though input tags with a type attribute of "image" are not being represented in the JavaScript elements array for the form.
Here's a mini-script to display a list of the element types within a form on a web page:
set formName to "loginForm"
set types to {}
tell application "Safari" to tell front document
set elementCount to do JavaScript "document." & formName & ".length"
repeat with elementNumber from 0 to elementCount - 1
copy (do JavaScript "document." & formName & ".elements[" & (elementNumber as text) & "].type") to end of types
end repeat
end tell
set text item delimiters to {space & "/" & space}
display dialog types as text
Before running, I find a web page with a login box, and look at the page code to find the name of the form in question, in this case "loginForm" and put that name in the first line of the script. Then I bring the page in question to the front and start the script.
For one page, I got the result "hidden / hidden / text / text / hidden / checkbox / password / checkbox / submit" and when I checked this against the page code, I found it was correct: there were nine <input> tags in the form, and their type attributes were in that order. But for another page, the home page of a major credit card, I got the result "hidden / text / password / select-one / checkbox" when I was expecting "hidden / text / password / select-one / image / checkbox." I've tried this with other pages and the behavior seems consistent: all types of <input> tags are represented in the elements arrays of their forms, except <input type="image"> which are always left out.
So, is this a bug or a feature? Or am I just unclear on the concept of the elements array? And if so, is there another way to find the submit element of a form when it is an "image"?
Incidentally, I'm not trying to be cagey by leaving out links to the pages I've tested. I'm just fairly new to discussion groups and was worried that linking to third-party pages for what amounts to a science experiment might not be the best net etiquette. If someone knows better, I will accept instruction. I hope my question is clear anyway, and there is no shortage of pages for experimental subjects.

True, it is not a matter of AppleScript per se. I did look for an Apple forum on JavaScript but didn't see one. OS X Technologies > AppleScript looked like my best bet: I've seen quite a few postings here where the answer to a question involved JavaScript, Unix shell scripts, PHP, etc., so I don't think I'm far off the mark. And I didn't think of a non-Apple JavaScript forum because I don't think my question is about JavaScript per se either: I suspect it is about Apple's implementation of JavaScript.
You're quite right about what I'm trying to do. I have a script that transfers secure data from my keychains into web forms, and there's really no need to trigger the form submittal programmatically when I have a perfectly good mouse and index finger, but it's become an enjoyable intellectual challenge to make it happen automatically. Incidentally, what you suggest may actually be a little dangerous these days: at any rate, that simple document.formName.submit(); method is more likely to fail than succeed.
Short version: physically clicking on a submit button on a web page in the conventional way is likely to invoke a lot of validity checking code in the page before the form is actually submitted. If, for example, there is a credit card number in the form, there will probably be code to do a Luhn checksum to make sure you've entered a real credit card number. If the validation fails, the submittal can be aborted. Using the .submit() method, by itself, does not trigger this validation code. (I fervently believe there is an excellent reason for this, but I've no idea what it might be.) Because of this, the form may be submitted with hidden element values that quite probably reflect the lack of validation. The server detects the anomaly, and instead of logging you in, it sends you to an error page. That's probably the best that can happen. I can think of worse.
My script has provisions to "play by the rules" by invoking any such validation code, and respecting its decision whether or not to proceed with submittal. I have the script working very well, but there's always the possibility of some web page designer doing something which I have not correctly anticipated. (In fact, since one possible place to put validation code invocations is in the "onclick" handler of the submit button, and since I'm having trouble finding some of these, I know I'm not covering all bases.)
A much more foolproof strategy would be to just simulate the physical clicking of a button. This is straightforward:
set submitButton to "document.formName.submitButtonName"
tell application "Safari" to tell front document
do JavaScript submitButton & ".focus();" & linefeed & submitButton & ".click();"
end tell
And to date I've never seen this method fail. But to do it, I have to have the name, or the array index, of the submit element of the form. I thought I knew how to find this, in the form's elements array, but I've run into a strange phenomenon. There are two kinds of submit buttons in forms: type="submit" and type="image". The type="submit" buttons do appear in the elements array, but the type="image" buttons apparently do not. And since web designers love to spiff up their pages, type="image" seems to be far more common these days.
I suspect this is just something that was accidentally left out of Apple's implementation of the JavaScript document model. I just thought I would ask if anyone else was aware of this, and could confirm or disconfirm. If no one does in the next day or so, I will bring the matter to the attention of the good people at Apple Bug Reporter.
All the best.

Extracting images from pdf

I am trying to extract images from pdfs using pdfimages, but i am unable to retrieve all the images. By opening the pdfs using Acrobat Reader 9.0, I am able to select, those images retrieved by pdfimages, using the select tool but for other figures/images we need to try other options like print screen and then cut the relevant image. I was wondering why or when does the Acrobat treats the figures/images differently.

Hi Dave,
Thanks for the reply. My question was not regarding any non-Adobe product like pdfimages. It was in general the way Acrobat handles the images while creating pdfs.
I wanted to know why can we select some of the images from the pdf using select tool and can not select others for which we need to print screen and cut. Is there anything in the eps files of included image that causes such effect?
Thanks.

How can I extract images from Numbers?

Sounds a bit stupid but how do you extract images from Apples 'Numbers 3' on a Mac? I have a client that sends images in XLS files, that normally in Word I would Alt Click and 'save as...'
I was trying to stop using Word but this simple little feature will make all the difference.
Can anyone point me in the right direction.
Thanks,
Dave

Hi Wayne,
Thank you for your response. Sadly if you do this it copies in to the MACs clipboard as a snap shot of the image at the dimensions in Numbers.
Eg.
An image I've extracted from the document via Excel saved out at it's original dimensions 1024 x 300px, even though it was placed, then scaled down to 300px wide on the sheet.
Same image copied then pasted in to an image editor (as I couldn't paste into finder) was only 300px wide.
The feature I need is to be able to save out the original image placed in the Numbers sheet.
Anyone with ideas on this?

I am reading PDF File.I need to extract images from PDF File programatically.But problem is that some images are stored inside PDF File using FlateDecode Filter and I need to first decode that file and then I can extract that image .I dont know the way to decode that image data.Is there any way or API to do that in C++.
Thanks

I think you can do it through cos object in VC++ plugin..go through the PDEFilterSpec in
Acrobat core api reference

Extracting Image Links From HTML

Hi, at the moment am trying to extract image locations from the html files i.e. the "src" part of <img> tag. Have tried using HTMLParserCallback as I know this allow you to extract links from a page. However when I open a document I know to have <img> tags in it, handleStartTag() is not called, I only get all the other tags. Any idea how to solve this problem? Thanks very much,
Ross

Hi,
Here's a portion of a class I wrote a while back....
Note the useMap variable I introduced in the constructor.
Some HTML files had the images in a "map" attribute, others in an "imgmap" attribute.
regards,
Owen
private class CallbackHandler extends HTMLEditorKit.ParserCallback
    private HTML.Tag tag;       // The most recently parsed tag
    private HTML.Tag lastTag;   // The last tag encountered
    private int nested = 0;
    private boolean useMap;
    public CallbackHandler(boolean useMap)
        super();
        this.useMap = useMap;
    public void handleText ( char[] data, int pos )
    public void handleStartTag ( HTML.Tag t, MutableAttributeSet attSet, int pos )
    public void handleSimpleTag ( HTML.Tag t, MutableAttributeSet attSet, int pos )
        if ( t.toString().equalsIgnoreCase ( "input" ) )
            boolean imagemap = false;
            String name = null;
            String src = null;

                        // Note : useMap is a boolean flag for you to set.
                        //        Some HTML pages used "map" attributes, others "imgmap" attributes
