Hi,

In relation to (1) check out this topic http://forums.adobe.com/message/2278262#2278262. I suspect that you cannot access the metadata since Acrobat cannot access even the file name.

Check out http://forums.adobe.com/message/1362353#1362353 for help on (2).

Good luck,

Hi Naill,

First I have to say thankyou for your answer.

About my (1) question, My image fields have set to be a embedded data and I try to test many example script of image fields.I can get image content type, image size. But that not work when I used ImageField1.desc.embeddedHref.value. It's response as "Unknown Embedded URI". Therefore, image field is and embedded data. How can I access filename?

(2) In that forum. As I see, his problem is about how to automate change image field with href image file. But I want to extract an exist embedded image in PDF form to normal image file with original metada (such as extract image filed to .JPEG with GPS data. Same as before attached in PDF form.). There has any concept or solution in this problem?

Best Regards,

Mai

Hi,

Here is an example of the embeddedHref for an imageField. Please note that this will only work when you embed an image into the field at design time. When the user changes the image at run time, the embeddedHref is NOT updated.

There is script in the docReady and Exit events, so you can see this in action.

I have never had to extract an image from a form. One poster had to do this and was achieving this through a database. But I don't know the details.

I don't think you will make much progress with (1), because the embeddedHref does not get updated. In relation to (2) I believe you can extract the images via a database connection; however you are going to have to research this some more, or someone else might have a direction.

Good luck,

Niall
