Can change the photo in a PDF file created with Spire.Word?

[Sungkyu_min]

Hi..


Assume that have converted a Word file to a PDF file using `Spire.word`.
There are 6 to 10 photos in the Word file, and I want to specify one specific photo and replace it in the PDF file using `spire.pdf`.

Previously, this work was done in Word, and alternative text was specified for each image.
This alternative text identifies what the image is in Spire.Word.

However, this task now has to be done in PDF rather than Word.
When converting a Word file to PDF with alternative text entered,
Is it possible to separate photos in `Spire.PDF` and change only those photos?

thank you for the reply.

However, I cannot find the `ResourceName` properties in the `PdfImageInfo` class.
Additionally, I also cannot find the `DeleteImage` method in the `PdfImageHelper` class.
Can you tell me what the problem is?

Code: Select all

using Spire.Pdf;
using Spire.Pdf.Graphics;
using Spire.Pdf.Utilities;
using Spire.Pdf.Exporting;
...
if (imagesInfos[i].ResourceName != "") { //Cna't find ResourceName
   ....
    //Remove the image
    pdfImageHelper.DeleteImage(imagesInfos[i]);   // Can't find DeleteImage
   ...
}

Hello,

Thank you for your feedback.
The code I provided to you is based on the latest version of Spire.PDF (Spire.PDF Pack (Hot Fix) Version: 10.2.2). Kindly upgrade the version of Spire.PDF in your project to this version before testing the code again.
Should you encounter any issues during the upgrade process or while testing the code, please do not hesitate to contact me for assistance.

Hi..

After updating from version 8.9.3 to 9.2 of Spire.Office, the issue has been resolved.

However, I believe I may have miscommunicated initially.
I had expected that the ResourceName would be entered as alternate text for the Word document, but in reality, it was not the case.

Previously, using Spire.Word, I was able to select a specific image as alternate text as follows:

Code: Select all

foreach (Paragraph docin in paragraphs) {
    foreach (DocumentObject obj in docin.ChildObjects) {
        if (obj.DocumentObjectType == DocumentObjectType.Picture) {
            DocPicture picture = obj as DocPicture;
            if (picture.AlternativeText == altTextName) {
                ... //My work
            }
        }
    }
}


Now, I want to work with Spire.Pdf instead of Spire.Word.
Assuming have a Word file with images containing specified alternate text and I converted it to PDF using Spire.Word,
Is it possible to identify specific images in a converted PDF file by their alt text that existed in Word?

Hello,

Thank you for your feedback.
We regret to inform you that Spire.PDF does not support the specific functionality you mentioned. Additionally, after converting a Word document to PDF, the PDF file will not retain the "AlternativeText" property from the Word document.
If you have any further questions or require assistance with any other features, please feel free to let us know.
Thank you for your understanding.
