How to Save an image and retreve the same image with edit option!! ???

I am facing with a problem
I have a image which is preloaded, user accessing the image should be provided with a option of adding a text on some part of image etc and save it. Later when that imagine is tried and retrived it should display the edited and saved image and allow user to edit again.The text will be written in a square box which can be dragged anywhere on the image. Is java script and ajax best for this.?
Can anyone help in showing the basic things i need to follow to achieve this.
Thanks in Advance

You could try to write a web service that returns a byte array and convert the image to bytes, and convert it back into an image again.

How can I make different catalogs from the same image

How can I make different catalogs from the same image where that image has been changed in some way between the catalogs. For instance if I wanted to have a catalogs for cropped images and have 3 catalogs one for 4x6 , 5x7 and 8x10 cropping. When I tried this , if I changed a file in one catalog that same image in the other would change also.

Do not confuse the creation of the crops and the display in collections per crop ratio.
Of course one virtual copy (VC) per crop ratio is needed. If the same image should be cropped in all 3 mentioned ratios there would be 3 VCs.
The OP asked how to have/see a set of same-crop-ratios.
After having created the virtual copies for whatever crop ratio he wants, the way to display this result in the fashion asked for is via smart collections, provided they can be found. Without a plugin the naming of the VC with the crop ratio applied is a straight way to achieve that.
IF the wish is to get new crops automatically added. (See my answers 2+3)
IF the wish is to creat static collections per crop ratio for a certain set of images, I'd go as follows:
1. Select all images you want to have cropped in that way,.
2. With this selection click on the + to add another collection and fill the dialog box like this:
Then navigate into this newly created selection and perform the 4x6 crop - according to taste individually or by synchronizing the first crop.

I can't send emails from Mail. I have three different accounts set up and have the same problem with all. The mail just sits in my outbox. All worked fine until Yosemite upgrade. Recent update has not fixed problem.

How to keep all text and formats the same on multiple computers?

I'm creating a file in InDesign CS6 on my Windows computer. I keep everything on my flash drive. When I go to school, I bring my flash drive with me and open it up on the Mac computer, but then there are are compatibility issues. There seems to be missing fonts and formats but the school uses the same version of InDesign I do. Now I was told a lot of things of how to keep the fonts and formats the same (embed the links, package the files, outline the text, save as IDML). However, it is not clear to me what each of those options do, so I don't know when or why to use them. So I just want to make sure that when I bring in my file in next Monday, I won't have any missing fonts or formats. What would you suggest is the proper things to do to keep everything the same on multiple computers? And could you please explain why?

If you want cross-paltform comaptibility limit the fonts to OpenType or Windows TrueType formats, both of which work on both Mac and PC. To avoid missing font warnings the fonts must either be installed on each computer, or they must be in a folder named Document Fonts in the same location as the .indd file they are to work with. Packaging the file will build taht folder for you.
the rest of the stuff in your list won't help you. .idml would allow you to open on an older version, but does nothing for your situation. Embedding the links will keep you from having missing links, but so will packaging, and embedded links will make the file much larger and harder to work with.
For goodness sake, don't even think about outlining the text. It stops being text when you do that and you can no longer edit it.
And finally. do yourself a big favor and don't attempt to actually work on your file directly from the flash drive. Copy the whole package folder to the hard drive, work on it, then copy back. You don't want to know how many files are fatally damaged by write errors on flash drives.

How do I relink multiple instances of the same image, in Illustrator CC?

Is there a feature, like InDesign, where links automatically relink if they're in the same folder?
Currently I have to search through the file structure multiple times even if the linked image is the same.
Surely Illustrator should relink all instances of the same image and give the option search for any additional missing links in the same folder?
I'd love to be pointed in the right direction, or if anyone has a script they've written to solve the problem, do let me know.
Cheers

try the script (version 3) in this post,
Remember last folder location lost with Mac Lion updates

How can I substract 2 pixels form the same image

I would like to know which library should I use from labview 7 and/or imaq vision so that I can substract the COORDINATES of 2 PIXELS from the SAME image.
THANKS !!!

Hello nobuto,
never worked with IMAQ by myself, but a collegue did...
He used a function "IMAQ Select Rectangle" to select a ROI (region of interest). You could do so for your 2 pixels. This functions gives you an "IMAQ Rectangle" (a cluster of 5 elements: top, left, right, bottom, rotation). You could uncluster the needed elements and do your subtraction.
Hope this helps.
Best regards,

How to insert into 2 tables from the same page (with one button link)

Hi,
I have the following 2 tables....
Employees
emp_id number not null
name varchar2(30) not null
email varchar2(50)
hire_date date
dept_id number
PK = emp_id
FK = dept_id
Notes
note_id number not null
added_on date not null
added_by varchar2(30) not null
note varchar2(4000)
emp_id number not null
PK = note_id
FK = emp_id
I want to do an insert into both tables via the application and also via the same page (with one button link). I have made a form to add an employee with an add button - adding an employee is no problem.
Now, on the same page, I have added a html text area in another region, where the user can write a note. But how do I get the note to insert into the Notes table when the user clicks the add button?
In other words, when the user clicks 'add', the employee information should be inserted into the Employees table and the note should be inserted into the Notes table.
How do I go about doing this?
Thanks.

Is there something wrong with the pl/sql code or is it something else?

Aperture replaces images with other images that have the same image number

Help! Aperture has started replacing images in recent projects with older images from elsewhere on my hard drive that have the same image number. Obviously I need a better numbering system, but can someone help me figure out why this is happening? I store master files on an external drive and the "replacement" files seem to be coming from identically named images on my local HD or in iPhoto.

I started renaming all of my images when I import them. I'm using referenced images to an external drive, although I still have a bunch of older images stored in the Aperture library under my old numbering system (which was basically whatever image number the camera generated)....need to move them all to the external drive but haven't had time.
So here's the latest problem: Today, Aperture started replacing images in albums (referenced images with unique file names under my new system) with old images even though the file names weren't even remotely close. It also replaced the images with the preview for the old image (230 pixels wide). "Show master" showed me the preview for the old image, not the correct image.
I tried forcing an update to the preview, but it had no effect. The real masters are intact on the external drive, but this is really scaring me. It happens out of the blue, right in front of me...I watch as my images appear to be replaced with random old images in Aperture. It appears to have nothing to do with file names, as I'm now using totally unique file names.

How can I fix the error image and get the regular image to load?

Ever since the recent big update for Firefox I've been getting some sort of error for loading certain images.
Here: http://tinypic.com/r/103bf3l/8 I have put one of those sites that give that error
--The original image that is supposed to show is also available in that image
Certain sites give a different size of that error image, but it looks the most like an error triangle
I've already tried the troubleshoot of not loading images and none of the options worked
If someone has this problem or knows how to fix it, it would be a great help

Solution found:
The addon "Stylish" with the theme "Google two themes" interfered with the image loading of the sites. Disabling the theme was the solution.

Display Image and Download the same in PDF

Hi...
We have requirement to display the Image of materials in the Web using the Web Dynpro ABAP.
We have the images in web server and URL for each image.
Once the image is visible in the web, user shoud be able to download the output in PDF copy with a button click in the screen.
The PDF output should be as in Web Screen output.
Can you please share how to achive this requirement using the Web Dynpro ABAP?
Thanks,
Guru

To display an image, simply use the "IMAGE" control in webdynpro.
To export to PDF, several options can be considered.
For example, try out the "INTERACTIVE FORM" control and embed your images dynamically into the form, or display the image in an ALV and use the PDF Print Preview function of the ALV.

Is there a batch process for opening multiple raw images and applying the same, stored preset?

I often have multiple exposures of the same subject, which I would like to treat identically. At present I have to open each one individually in Camera Raw, apply the preset, save, go on to the next, etc.
Looking for a way, if there is one, to select them all, in order to apply the preset to all at once. Or perhaps there may be a scripting method to allow this?

Which version of photoshop, camera raw and operating system are you using?
You should be able to open all the images inside camera raw, Select All (upper left of the camera raw dialog above the filmstrip of open images) and then apply the settings to all the selected images.

I don't have AI 13 (CS3), but in AI 12 (CS2), I get the same pixel dimensions for both .jpg and .gif versions created via Save for Web (using your 350x200 example).
