PdfImageInfo bounds alway 0 and original image

[aibizcore]

Hy,

invoking the "page.ImagesInfo", the "Image Boundary location" returns alway zero's.

We need to process images with custom function, and replace in the PDF:

To do this, de Imagesinfo must return the original image (or stream) from the pdf (like ExtractImages (false)) and the Bounds information.

Is that possible or is and another way to do this?

Spire.PDF version 3.10
thanks,
JD

Hello,

Thanks for your feedback. I have noticed location issue and logged it into our bug tracking system. If there is any update, we will let you know. We apologize for the inconvenience.
On the other hand, Imagesinfo could return the original image and you could use page.ReplaceImage(index,PdfImage) to replace the image. Please see below.

Code: Select all

            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile("test.pdf"); ;
            var inf=doc.Pages[0].ImagesInfo;
            var image = inf[0].Image;
            //replace image
            doc.Pages[0].ReplaceImage(1, PdfImage.FromImage(image));
            doc.SaveToFile("replace.pdf",FileFormat.PDF);
