用强大的 PDF 批注功能简化审查

1月 10, 2025
用 React PDF 批注轻松高亮显示、评论和自定义文档，从而提高每个审查过程的工作效率和清晰度。

PDF annotations in PDF Viewer components allow users to interact with and mark up documents directly within an application. This functionality is critical for workflows requiring collaborative review, document editing, or enhanced personalization of PDFs, offering a seamless experience for annotating without requiring external tools. By embedding annotation capabilities, applications can boost productivity and streamline document-centric tasks.

Common features include:

  • Freehand Draw (Ink Annotation) allow users to draw freeform shapes, lines, or highlights directly onto a PDF using a stylus, mouse, or touch input.
  • Lines allow users to underline text, create dividers, or connect different areas of the document for clear and professional markup.
  • Rectangles are ideal for framing sections of a document. Users can highlight specific text or data, making it stand out without permanently altering the original content.
  • Ellipses enable users to easily call attention to charts, images, or other graphical elements.
  • Stamp annotations let users apply predefined or custom stamps, such as "Approved," "Rejected," or company logos. This provides a fast and visually impactful way to signify document status or ownership.
  • Free Text annotations allow users to add independent text boxes anywhere on the document. This tool is helpful for inserting notes, instructions, or additional details without modifying the underlying content.
  • Watermarking PDFs embeds text or images, such as "Confidential" or a company name, across a PDF. It ensures documents are properly branded or marked for security purposes without obstructing readability.

确保符合 Highcharts 许可证更新

1月 6, 2025
Highcharts 按照 SaaS 许可证对公共网站部署进行了重新分类，要求一些用户更新协议以符合新条款。

Effective January 6, 2025, Highcharts has streamlined its licensing model to enhance clarity, simplify compliance, and improve the overall user experience. The updates include unified definitions, revised license grants, and an upgraded ADV+ support offering.

  • Streamlined Definitions
    The terms “SaaS application” and “web application” have been replaced with a unified term: "External Application". This new terminology clarifies the distinction between applications covered under the Internal License and those requiring additional licensing.

  • Updated License Grants
    Public websites, previously covered under the Internal License grant, are now under the SaaS License grant. This ensures consistency across applications for public access.

  • Video Call Support for ADV+ Subscribers
    Users subscribed to the Highcharts Advantage Plus (ADV+) tier now benefit from video call support, providing more robust communication options for troubleshooting and guidance.

For existing customers using the Internal License to deploy on public websites, these updates reclassify such use under the SaaS License grant. The updated Highsoft license terms mean that customers currently using an Internal License for an external Public Web site or for an “External Application” will need to upgrade to a SaaS License to ensure compliance. For more information see our updated Highcharts Core licensing page.

If you have questions about Highcharts licensing, our experts are here to assist. Whether you need guidance on selecting the right license, moving to a new agreement, or ensuring compliance, we’re ready to help via toll-free phone, live chat or email.
