Provides CSS-only overlay positioning techniques for layering text and menus over images.
LogicFlow is an SVG-based flowchart editing framework and visual graph editor used for building customizable business process diagrams. It serves as a customizable diagramming engine for rendering business process models, entity relationship diagrams, and unified modeling language charts. The system is characterized by a plugin-based architecture that allows developers to define specialized graphical elements and register pluggable modules. A distinctive feature is its overlay system, which positions standard HTML components on top of the SVG canvas to create interactive menus and control pan
Positions standard HTML components on top of the SVG canvas to create interactive menus and control panels.
bpmn-js is a browser-based BPMN 2.0 web modeler and rendering engine used for creating, editing, and visualizing business process models. It functions as an XML process modeler that parses BPMN 2.0 XML data into interactive visual diagrams within a web application. The project distinguishes itself as a business process visualizer with capabilities for process flow simulation, which tracks token movement to mimic real-time execution. It also supports diagram version comparison to identify changes between model iterations and provides a layered overlay interface for binding metadata and custom
Implements HTML elements positioned over the SVG canvas to provide interactive metadata and markers.
CSS Layout is a pure CSS pattern library that provides pre-built layout components for common page structures, implemented entirely with CSS using flexbox and grid. The collection focuses on reusable, encapsulated components that handle overlapping elements, vertical centering, sticky footers, and classic page layouts without requiring any JavaScript for rendering or interactivity. The library offers a range of practical layout implementations including centered navigation menus, element stacking techniques, holy grail page layouts, and responsive grid systems. Each pattern is built as a self
Provides CSS-only overlay positioning techniques using absolute positioning and grid for stacking elements.
Jcrop ist eine JavaScript-Bibliothek zum Zuschneiden von Bildern, die eine browserbasierte Schnittstelle bietet, mit der Benutzer interaktiv rechteckige Bereiche eines Bildes auswählen und definieren können. Sie nutzt ein DOM-basiertes Bild-Overlay, um Bilder in relative Container einzubetten, was die Platzierung von anpassbaren Auswahl-Handles und Begrenzungseinschränkungen ermöglicht. Das Tool zeichnet sich durch umfassende Eingabeunterstützung aus, die Touch-Gesten und Tastatureingaben in präzise Koordinaten-Updates für mobile und Desktop-Umgebungen übersetzt. Es verfügt über eine Engine, die benutzerdefinierte Seitenverhältnisse erzwingen und die optimale Passform für Auswahlbereiche berechnen kann, um konsistente Ausgabeabmessungen zu gewährleisten. Die Bibliothek deckt ein breites Spektrum an Bildbearbeitungsfunktionen ab, einschließlich Koordinatentransformation, Durchsetzung von Auswahlgrenzen und Verwaltung mehrerer Crop-Bereiche. Sie bietet ereignisgesteuerte Status-Synchronisierung zur Verfolgung von Interaktionsänderungen und ermöglicht die Wiederherstellung zuvor gespeicherter Crop-Zustände. Benutzer können das Verhalten und das Erscheinungsbild des Tools durch Interface-Styling-Optionen und klassenbasierte Logik-Erweiterungen anpassen.
Implements interactive layers positioned precisely over images to facilitate region selection.
This project provides a React component and a set of utilities for implementing interactive image cropping. It enables users to define selection areas over media elements using a draggable and resizable interface. The library supports fixed aspect ratio locking and the definition of custom crop shapes, such as circles. It utilizes a percentage-based coordinate system to ensure the selection interface remains responsive across different screen sizes and layouts. The toolset includes capabilities for real-time crop previewing and the generation of cropped regions using canvas-based rendering.
Utilizes absolute positioning and CSS transforms to align the crop selection overlay with the image.
