Copie o conteúdo diretamente do seu visualizador de PDF

Outubro 13, 2025
Selecionar e copiar texto é essencial para citar, compartilhar ou analisar conteúdo, e os visualizadores modernos tornam isso rápido, preciso e pronto para a área de transferência.

Selecting and copying text is a core feature of PDF viewer components, allowing users to highlight, extract, and paste content from documents without needing an external PDF editor. This capability is essential in workflows where text needs to be reused, such as quoting, data extraction, or forwarding snippets. A well-implemented text selection feature supports precise region selection, preserves text formatting and order (even across lines or columns), and integrates with the system clipboard reliably.

Several Angular PDF viewer controls offer the ability to select and copy text from PDF files, including:

  • Wijmo PDFViewer (part of Wijmo by MESCIUS) lets you enable PDF text selection and copying, so users can easily highlight and extract content directly from documents.
  • Kendo UI PDF for Angular (part of Kendo UI by Telerik) allows users to select and copy text from PDF documents by enabling simple viewer commands, improving accessibility.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) offers built-in text selection capability that allows users to select and copy text to the clipboard.

Visualize tendências geográficas com gráficos de mapa

Outubro 9, 2025
Descubra insights com visualizações geográficas codificadas por cores usando gráficos de mapas interativos que revelam padrões regionais e destacam as principais métricas.

A map chart is a data visualization tool that displays information across geographic regions, helping users uncover spatial patterns, trends, and relationships. By plotting values onto countries, states, or custom areas, it transforms complex datasets into clear, location-based insights. Features like color-coding, zooming, and drill-down navigation allow for interactive exploration and comparison across regions. Common use cases include analyzing sales performance by region, tracking market coverage, visualizing customer distribution, or monitoring demographic trends, all of which support data-driven decision-making with a strong geographic context.

Several JavaScript chart controls offer map charts including:

  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) lets you visualize geographic data with interactive map charts, enabling detailed spatial insights.
  • Highcharts Core by Highsoft allows you to create dynamic map charts with drill-down capabilities, gradient coloring, and responsive designs for geographic data exploration.
  • AnyChart JS facilitates clear spatial analysis through customizable map charts featuring tooltips, projections, and region-based color differentiation for deeper insight.
  • Syncfusion JavaScript Chart (part of Syncfusion Essential Studio Enterprise) lets you build map charts with real-time data updates, heatmap overlays, and intuitive navigation.

Simplifique a entrada de dados com caixas de seleção intuitivas

Outubro 8, 2025
Gerencie facilmente valores verdadeiro/falso em grades com células de caixa de seleção integradas que melhoram a clareza por meio de interações rápidas, precisas e visualmente claras.

A checkbox cell type in a grid allows users to easily manage Boolean (true or false) data through a simple and visual interface. Instead of typing values manually, users can quickly toggle a checkbox to indicate states such as active or inactive, complete or incomplete, or enabled or disabled. This interaction reduces input errors and enhances data clarity, making it easy to scan and understand information at a glance. Checkbox cells improve productivity by supporting quick edits, bulk selections, and efficient filtering based on checked or unchecked values. Common use cases include task tracking, user permissions, product availability, and feature toggles where a binary choice improves workflow efficiency and usability.

Several Vue.js grid components offers checkbox cell type support, including:

  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete) lets you add checkbox cells for quick true or false selections, enhancing clarity and data entry.
  • DataViewsJS by MESCIUS facilitates efficient data handling with checkbox cells, allowing users to toggle states instantly and visualize binary values effortlessly.
  • Handsontable by Handsoncode allows you to include checkbox cells for intuitive Boolean input, enabling fast updates and easy filtering within editable grids.
  • IntegralUI Grid (part of IntegralUI Web by Lidor Systems) enables checkbox cell integration, ensuring accurate Boolean data management and enhancing usability in interactive grids.
