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 este o bibliotecă JavaScript pentru decuparea imaginilor (image cropping) care oferă o interfață bazată pe browser pentru ca utilizatorii să selecteze și să definească interactiv regiuni dreptunghiulare ale unei imagini. Utilizează un overlay de imagine bazat pe DOM pentru a înfășura imaginile în containere relative, permițând plasarea de mânere de selecție ajustabile și constrângeri de limită. Instrumentul se distinge prin suportul cuprinzător pentru input, traducând gesturile tactile și interceptările de la tastatură în actualizări precise de coordonate, atât pentru medii mobile, cât și desktop. Dispune de un motor capabil să impună constrângeri de aspect ratio personalizate și să calculeze potrivirea maximă pentru zonele de selecție, asigurând dimensiuni de ieșire consistente. Biblioteca acoperă o gamă largă de capabilități de manipulare a imaginilor, inclusiv transformarea coordonatelor, impunerea limitelor de selecție și gestionarea zonelor multiple de decupare. Oferă sincronizarea stării bazată pe evenimente pentru a urmări schimbările de interacțiune și permite restaurarea stărilor de decupare salvate anterior. Utilizatorii pot personaliza comportamentul și aspectul instrumentului prin opțiuni de stilizare a interfeței și extensii de logică bazate pe clase.
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.
