Programmatically generate image representation of PNG document pages using the document preview feature to set watermark position and styling within the document. This feature is useful to better visualize the document structure and content positioning after the watermark is added to PNG document.
Generate the document preview in JPG, PNG or BMP image formats for the whole document or choose specific pages as your require.
What is PNG file format?
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.
