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

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

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

Jcrop es una librería de recorte de imágenes en JavaScript que proporciona una interfaz basada en navegador para que los usuarios seleccionen y definan interactivamente regiones rectangulares de una imagen. Utiliza una superposición de imagen basada en DOM para envolver imágenes en contenedores relativos, permitiendo la colocación de manejadores de selección ajustables y restricciones de límite. La herramienta se distingue por su soporte de entrada integral, traduciendo gestos táctiles e intercepciones de teclado en actualizaciones de coordenadas precisas tanto para entornos móviles como de escritorio. Cuenta con un motor capaz de aplicar restricciones de relación de aspecto personalizadas y calcular el ajuste máximo para áreas de selección para garantizar dimensiones de salida consistentes. La librería cubre una amplia gama de capacidades de manipulación de imágenes, incluyendo transformación de coordenadas, aplicación de límites de selección y la gestión de múltiples áreas de recorte. Proporciona sincronización de estado basada en eventos para rastrear cambios de interacción y permite la restauración de estados de recorte guardados previamente. Los usuarios pueden personalizar el comportamiento y la apariencia de la herramienta a través de opciones de estilo de interfaz y extensiones de lógica basadas en clases.

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.
