Check image type and size in an interactive pdf Adobe acrobat pro dc

[Sachan231918648pcr]

I have an image field which allow users to import an image with event.target.buttonImportIcon().
How can I check for image type (for ex :- jpeg) and file size after the image is imported ?

Once an image is imported, it is a PDF image - it is no longer a JPEG, PNG or any kind of external file. Similarly you don't know how much size it adds to the PDF. You can export it to get the size (if not automatically) but that won't be the size of the original image file.

Thank you for the explanation, is there a way to achieve this ? maybe a workaround ?

You can't. A script has no access to this information. I don't think it's even available in the PDF file at all.

What you can do, though, is check the file size of the PDF file before and after the image is added to it... You might need to save it first, though.

"maybe a workaround ?"

May be by importing an attachment, see this topic:
