PdfThumbnail pdfThumbnail = new PdfThumbnail(); pdfThumbnail.setResource(new DownloadStreamResource("https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf")); pdfThumbnail.setPreviewWidth(400); pdfThumbnail.setWidth("300px"); pdfThumbnail.setHeight("300px"); layout.addComponent(pdfThumbnail); public static class DownloadStreamResource extends StreamResource { private String url; public DownloadStreamResource(String url) { super((StreamSource) () -> { try { return new URL(url).openStream(); } catch (IOException e) { e.printStackTrace(); return null; } }, "download.pdf"); } }
