No, you missunderstood me. I need to shrink the pdf to the size of the image inside of that pdf. Resizing an existing pdf with many pages which look like the example i gave you

Hi Mvxyc, 

Thank you for your update. 

 

We have created a sample for reducing the PDF document size, for compressing the existing images and replace it. Please find the below code snippet and sample for more details. 

 

           //Loads the PDF document which c images 

            PdfLoadedDocument loadedDocument = new PdfLoadedDocument(Server.MapPath("../App_Data/example.pdf")); 

 

            //Disables the incremental update 

            loadedDocument.FileStructure.IncrementalUpdate = false; 

 

            //Iterates all the pages to replace images 

            foreach (PdfPageBase page in loadedDocument.Pages) 

            { 

                //Extracts the images from the document 

                Image[] extractedImages = page.ExtractImages(); 

 

                //Iterates all the image 

                for (int j = 0; j < extractedImages.Count(); j++) 

                { 

                    PdfBitmap img = new PdfBitmap(extractedImages[j]); 

 

                    //Reduces the quality of the image 

                    img.Quality = 50; 

 

                    //Replaces the compressed image with old image in the PDF document 

                    page.ReplaceImage(j, img); 

                } 

            }

no, this not what iam looking for. Inside "example_4302c8ed.7z" there is a pdf, which contains an Image, the problem here is that the pdf is huge(i think 6000x6000), I want to extract that picture and save it to a new file.But I dont know how ?!

Hi Mvxyc, 

Thank you for your update. 

PdfPage.ExtractImages method helps to extract the images form the existing PDF document. We have created a sample for extracting the images from existing PDF document and save it to the new PDF document for your reference. Please refer the below sample for more details.
