Replace images with text

Hello,

I've a PDF document with a table that has several rows. In two columns of this table there are some icons (images) that I would like to replace with a text. The replacement text should be related to the effective icon replaced.

Example
There are three kind of icon: one represent "Accepted", one "Rejected" and the last "Pending".
In a column of a table, for each row, one of those three icons appears.

How can I, using the PDF control, replace all the icons representing "Accepted" with the text "OK", all the icons representing "Rejected" with the text "KO" and all the icons representig "Pending" with the text "PP"?

Is there a way to extract information about an image in the PDF file that could tell me information like its name or some other information usefull to its identification?

Any suggestion is highly apreciated.

Hello,

Thank you for your example but it is not what I want to achive. I think you misunderstood my request.
In the example you use ocr to find an image that has the text "PDF" in it and then replace that part of the image with the graphic rapresentation on another text.

I don't need to replace text in an image.
I need to replace the whole image with some text that has to be inserted in the output PDF as "text" and not as "image".

I thought I could scan the PDF structure, look at the images contained, categorize them by some information they have (here is where I need help as I don't know what informations the Image object has) and then replace all images of a certain category with a specfied text. I don't think there is any need to ocr the PDF as images don't contains any text at all.

Thanks for your help.

Hello,

Here's a sample PDF. I need to replace the images that are next to the numbers with a text that is related to the specific image. Same image means same text.

Thanks.

Hi Arturo, 
 
Thank you for your patience. 
 
We have analyzed your requirement, it is not possible to replace the image with text, we could not find the same images in PDF pages and we could replace it with some text. We can only replace the images with some other images. So, we could not proceed further on this.
