Replace image hangs

[Gyorgy Gorog]

Hi, I have a PDF in which I want to replace all images with their grayscale version.

At page 54, image 5 (0-based: page53, image 4) it hangs forever at the page.ReplaceImage call.

Also there are a lot of images that are not extracted as images. Please advise how they can be accessed.

Snycfusion.Pdf.Winforms 18.2.0.54. Memory usage is 77 MB.

My code is: 

PdfLoadedDocument origDoc = new PdfLoadedDocument(origFile) {EnableMemoryOptimization = true};

int pagesCount = origDoc.Pages.Count;

for (int pageIndex = 0; pageIndex < pagesCount; pageIndex++)

{

       PdfPageBase page = origDoc.Pages[pageIndex];

       //if (!page.IsColored ) continue;

       Image[] images = page.ExtractImages();

       for( int i = 0; i < images.Length; i++ )

       {

            Image image = ToolStripRenderer.CreateDisabledImage(images[i]);

            PdfBitmap pdfImage = new PdfBitmap( image );

            page.ReplaceImage(i, pdfImage); // it stays here forever

       }

}

Hi Gyorgy,  

Thank you for using Syncfusion products.

Gowthamraj, thanks for update.

Just some additional information:

If I export the PDF to Word, and then save it as PDF, ImageReplace does not hang.

This is a possible but not very elegant workaround.

Thanks!
