Vandmærke PNG-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 PNG-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 PNG-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.
PNG, short for Portable Network Graphics, stands as a raster graphics file format renowned for its lossless data compression and its suitability for displaying images on the web. It has gained significant popularity among graphic designers and photographers who seek to store and showcase high-quality images. One of the distinctive features of PNG files is their support for transparency, setting them apart from JPEG files that cannot contain transparent areas.
The PNG file format provides several advantages that contribute to its appeal. Firstly, it supports 16-bit color, enabling the preservation of more accurate colors during image editing processes. This feature proves valuable for professionals working with intricate color details. Additionally, PNG supports gamma correction, ensuring that images display correctly across various systems. This capability helps to maintain consistent visual quality across different devices and platforms.
Furthermore, PNG employs lossless data compression, allowing for efficient reduction of file size without compromising image quality. This compression technique facilitates faster download times and improved web page loading performance. The smaller file sizes make PNG files more convenient to store, transfer, and share, making them an ideal choice for web-based applications.
PNG files have gained widespread support across major web browsers and operating systems, further contributing to their popularity. This compatibility ensures that PNG images can be reliably viewed and displayed across different platforms and devices, enhancing accessibility and user experience. Moreover, PNG is widely supported by various image editing and drawing software programs, including industry-standard applications like Adobe Photoshop. This compatibility allows professionals to work seamlessly with PNG files, leveraging advanced editing capabilities to achieve their desired outcomes.
