TOCropViewController

TOCropViewController es un controlador de vista UIKit diseñado para el recorte y rotación de imágenes dentro de aplicaciones iOS. Proporciona una interfaz visual de edición de imágenes que permite la extracción de secciones específicas de la imagen utilizando una cuadrícula superpuesta arrastrable.

El componente admite la selección de relaciones de aspecto personalizadas y el enmascaramiento circular para asegurar que las fotos se ajusten a diseños predefinidos, como los requeridos para la edición de fotos de perfil. Incluye una interfaz dedicada para cambiar la orientación de la imagen y realizar ajustes de rotación.

La herramienta maneja el procesamiento de imágenes traduciendo las posiciones de la cuadrícula de la interfaz de usuario a coordenadas de píxeles y exportando el contenido recortado resultante. La comunicación con la aplicación que realiza la llamada se gestiona a través de un protocolo de transferencia de datos basado en delegados.

Features

  • Image Cropping Components - Provides a specialized UIKit component for defining and adjusting crop areas with a draggable grid overlay.
  • Rotation and Shear transforms - Provides geometric transformations to update image orientation and grid alignment through rotation.
  • Crop Area Masks - Uses shape masks and clipping paths to render the selected crop area as a circle or specific aspect ratio.
  • Cropped Image Exporters - Provides utilities to export the final cropped image data to internal delegates or system share sheets.
  • Image Orientation Manipulators - Includes a dedicated user interface for adjusting the visual orientation of images via rotation.
  • iOS Photo Manipulation - Enables changing the orientation and framing of images to prepare them for storage or sharing on iOS.
  • Image Editing Interfaces - Offers a visual tool for extracting image sections using custom aspect ratios and circular masks.
  • View-to-Image Coordinate Mapping - Implements logic to translate screen touch and grid coordinates into raw image pixel coordinates for precise cropping.
  • Preset Aspect Ratios - Allows users to restrict image cropping to predefined aspect ratios to ensure photos fit specific layouts.
  • Profile Photo Framing - Provides a dedicated interface for cropping and rotating photos to fit the dimensions required for account avatars.
  • Image Processing - View controller for image cropping.
  • Media Processing - Image cropping view controller.

    Android-Image-Cropper is an image cropping library for Android applications designed to trim and resize photos sourced from cameras or galleries. It functions as a bitmap manipulation tool capable of rotating, flipping, and scaling images to achieve specific dimensions. The library features an aspect ratio constrained cropper that limits the cropping window to fixed shapes or ratios to ensure consistent image output. It handles orientation adjustments by reading embedded metadata to automatically rotate or flip images during the cropping process. The toolkit covers a broad range of image pro
