ReplaceImage not working correctly with Template

Postby raku » Wed Aug 09, 2017 7:02 am

Hi,

I would like to report / ask for feedback on handling ReplaceImage() when PDF Template is used.
So what is the problem:
When I'm invoking following code on regular PDF created with SpirePDF it works ok
Code: Select all
...
var image = PdfImage.FromStream(replacement);
page.ReplaceImage(0, image);


But when I add header / footer to given PDF using this code

Code: Select all
              headerSize = 40;
              var topSpace = new PdfPageTemplateElement(_doc.PageSettings.Size.Width, headerSize.Height)
              {
                  Foreground = true
              };
              _doc.Template.Top = topSpace;
              topSpace.Graphics.DrawString(header, font, PdfBrushes.Black, originalMargins.Left, 0);
           
            foreach (PdfPageBase origianlPage in original.Pages)
            {
                var page = _doc.Pages.Add(new SizeF(origianlPage.Size.Width, origianlPage.Size.Height));
                origianlPage.CreateTemplate().Draw(page, 0, -(headerSize));
            }

then ReplaceImage code from above clears entire PDF (it leaves only header all content is removed).

This is for sure something with this line
Code: Select all
origianlPage.CreateTemplate().Draw(page, 0, -(headerSize));

but i cannot figure out what exactly is going on.

Any ideas / help?

Hello,

I got the news from our dev team that the page.ReplaceImage() method can only be available for the images for the body part. If the image is in the header, mistake might occur like yours.
So sorry for the inconvenience caused.

Sincerely,
Jane

Hi again,

Maybe I described it differently but the image is in "body" not in the header of footer.
In my my example that I've posted see that header contains only text.
Code: Select all
topSpace.Graphics.DrawString


The image is in the body of the source pdf (before template function was used). So to speak image is placed inside "origianlPage" in previous example:
Code: Select all
origianlPage.CreateTemplate().Draw(page, 0, -(headerSize));


And only after applying CreateTemplate().Draw... the PDF that is created cannot be manipulated using ReplaceImage()
