![]() Var targetFile = Path.Combine(OutputFolder, fileName "_" i ".png") įor starters, you need to take the following steps to get the PDFium wrapper up and running: Var grahpics = Graphics.FromImage(bitmap) Using (var bitmap = new ((int)page.Width, (int)page.Height)) Using (PDFiumSharp.PdfDocument doc = new PDFiumSharp.PdfDocument(Inputfile))įor (int i = 0 i < i ) String fileName = Path.GetFileNameWithoutExtension(Inputfile) Public void RenderPDFAsImages(string Inputfile, string OutputFolder) Regarding PDFiumSharp: After elaboration I was able to create PNG files from a PDF solution. ![]() Var bitmap = fpdfview.FPDFBitmapCreateEx(įpdfview.FPDFBitmapFillRect(bitmap, 0, 0, width, height, (uint)()) įpdfview.FPDF_RenderPageBitmapWithMatrix(bitmap, page, matrix, clipping, (int)RenderFlags.RenderAnnotations) īitmapImage.Save("test.jpg", ImageFormat.Jpeg) įor a thread safe implementation see this: Var height = (int)Math.Round(size.Height * scale) Var width = (int)Math.Round(size.Width * scale) Var page = fpdfview.FPDF_LoadPage(document, pageIndex) įpdfview.FPDF_GetPageSizeByIndexF(document, 0, size) Var document = fpdfview.FPDF_LoadDocument("test.pdf", null) Here's a simple single thread code: var pageIndex = 0 Note: If you want to use it on Linux you should install 'libgdiplus' as suggests. As PDFiumCore use a much newer version of Pdfium (that seems to be a critical point for using a pdf library) I ended up using it. Searching for a powerful and free solution in dotnet core that works on Windows and Linux got me to and. Image.Save(imageJpgPath, new JpegEncoder()) Image.Mutate(x => x.BackgroundColor(Rgba32.White)) Set the background to white, otherwise it's black. ![]() Var image = Image.Load(pageBitmap.AsBmpStream()) Var imageJpgPath = string.IsNullOrWhiteSpace(thumbnailPath) Using var pageBitmap = new PDFiumBitmap(width, height, true) Using var pdfDocument = new PdfDocument(pdfPath) Public static void SaveThumbnail(string pdfPath, string thumbnailPath = "", int width = 300, int height = 423) / which corresponds to the aspect ratio of 'A' paper sizes like A4 (ratio h/w=sqrt(2)) / Saves a thumbnail (jpg) to the same folder as the PDF file, using dimensions 300x423, the Bitmap stored at that position in the myImages ArrayList in the TiffImage imageBox is a PictureBox control, and the operators pass back TiffImage myTiff = new TiffImage("D:\\Some.tif") Use it like so: private void button1_Click(object sender, EventArgs e) MyImage.SelectActiveFrame(myDimension, i) MyPageCount = myImage.GetFrameCount(myDimension) MyDimension = new FrameDimension(myGuid) Public ArrayList myImages = new ArrayList() įileStream fs = new FileStream(myPath, FileMode.Open) If you use this process to convert a PDF to tiff, you can use this class to retrieve the bitmap from TIFF.
