  Hi,

  I use SVG pictures as background of my cells
  
  testsvg.zip
  
  but when I export them in PDF format, the pictures are no longer in SVG
  
  testsvgpdf.zip

  Is there a way to keep my SVG format in the pdf file?

  thanks

  Hi,

  We are currently investigating the method to verify image formats within a PDF. Could you please share the details of how you are checking image formats in a PDF, or if you are utilizing any specific libraries for this purpose?

  Best regards,

  Ankit

  if zooming in on images doesn’t convince you, you can use the python script:

  import PyPDF2
  from PIL import Image
  from io import BytesIO
  
  def extract_image_extensions(pdf_file):
      image_extensions = set()
  
      try:
          with open(pdf_file, 'rb') as file:
              reader = PyPDF2.PdfReader(file)
              num_pages = len(reader.pages)
              
              for page_num in range(num_pages):
                  page = reader.pages[page_num]
                  images=page.images
                  for obj in images:
                      print(obj.name)
                  
      except Exception as e:
          print(f"Une erreur s'est produite : {e}")
  
      return image_extensions
  
  pdf_file_path = "c:\\python\\exemple.pdf"
  extensions = extract_image_extensions(pdf_file_path)
  print("Extensions des images dans le fichier PDF:", extensions)

  The result for my pdf are:
  
  I1.png
  
  I2.png
  
  I3.png

  Hi,

  I was able to observe the same behavior with the PDF file exported from the SpreadJS. I have escalated it to the concerned dev team for further investigation.

  The internal tracking id for the same is: SJS-22607 and I will let you know when there is more info on this from the dev team.

  Hi,

  The devs have mentioned that this is the limitation of the current implementation. The SpreadJS uses Canvas to render everything in sheets, and when generating PDF, all the images will use Canvas API to generate directly, and therefore, the images will be pixilated and not SVG.
