Vandmærke PDF-filer i Java-applikationer ved hjælp af populære vandmærketyper såsom tekst, billede, XObject, artefakt, annotering og formvandmærker uden brug af ekstern software eller vandmærkeværktøj. Brug avanceret sæt vandmærkestyringsfunktioner – tilføj nemt vandmærker til vedhæftede billeder, dokumenter samt vedhæftede filer i e-mail, tekstbehandlingsdokumenter, Excel-regneark, PowerPoint-præsentationer og Visio-diagrammer.
HentJava vandmærkebibliotek gør det nemmere for udviklere at tilføje BMP, PNG, GIF eller JEPG som billedvandmærke til PDF-filen ved at tilføje et par nemme trin.
Nedenstående Java-kodeeksempel kræver GroupDocs.Watermark
navneområder for at indsætte billedvandmærker til en lang række understøttede filformater. Tilføj og se det vandmærkede dokument på forskellige operativsystemer såsom Windows, Azure, Linux (Ubuntu, OpenSUSE, CentOS og andre) eller macOS, mens du arbejder på Java J2SE-udviklingsplatformen.
Hent de respektive filer fra Hent eller hent hele pakken fra Maven for at tilføje Conholdate.Total
direkte i dit arbejdsområde.
Dette Java-kodeeksempel viser, hvordan man tilføjer tekstvandmærke til et PDF-dokument ved hjælp af et par enkle linjer Java-kode. Vandmærket vil blive tilføjet til alle siderne i kildedokumentet.
Generer automatisk billedrepræsentation af dokumentsider ved hjælp af dokumenteksempelfunktionen til at indstille vandmærkets placering og stil i dokumentet. Denne funktion er nyttig til bedre at visualisere dokumentstrukturen og indholdets placering, efter at vandmærket er føjet til kildedokumentet.
Generer dokumenteksemplet i JPG-, PNG- eller BMP-billedformater for hele dokumentet, eller vælg specifikke sider efter behov.
PDF (Portable Document Format) is a widely used document file format developed by Adobe Systems in 1993. It was specifically designed to provide a platform-independent solution for storing and sharing documents across various operating systems and over the Internet. PDFs utilize a vector-based drawing model, storing graphical elements such as lines, shapes, and images as mathematical equations. This unique approach ensures that PDFs are resolution independent, guaranteeing consistent document quality regardless of the viewing device or program.
One of the key advantages of PDFs is their support for a range of security features. Encryption, password protection, digital signatures, and document watermarking are among the security measures available. These features make PDFs highly secure and suitable for sensitive documents, such as medical records, legal documents, government forms, and invoices. The printing industry also heavily relies on PDFs to facilitate electronic communication with customers.
Creating PDFs is a straightforward process, as they can be generated from various electronic document formats, including Word documents, PowerPoint presentations, and webpages. It’s important to note that PDFs are typically not editable directly. To modify the content of a PDF, it must first be converted to a different file format that supports editing. Numerous software programs, many of which are freely available for download, offer the functionality to convert PDFs to editable formats.
PDFs have gained immense popularity and have become a standard method for document sharing due to their versatility, security features, and consistent formatting. Their compatibility across different devices and operating systems ensures seamless document access for users. Additionally, PDFs preserve the layout, fonts, and images of the original document, making them an ideal choice for sharing visually rich content.
