Give it the path of an image and new dimensions and it will generate a new image with these dimensions. To resize local image files, we created react-native-image-resizer. There are 53 other projects in the npm registry using react-image-file-resizer. Start using react-image-file-resizer in your project by running npm i react-image-file-resizer. Latest version: 0.4.8, last published: a year ago. The URI can be used as the source of an component.You can use it as a template to jumpstart your development with this pre-built solution. â Installing and using react-native-image-resizer It returns resized image's new base64 URI or Blob. image resize / compressor - Codesandbox image resize / compressor Edit the code to make changes and see it instantly in the preview Explore this online image resize / compressor sandbox and experiment with it yourself using our interactive online playground. Our package helps you with this situation by allowing image resizing directly from React Native. We are a 100 people company developing and designing multiplatform applications with React Native using the Lean & Agile methodology.Whenever your app requires the user to take a picture with the camera, or from the camera roll, the image is so heavy that it takes ages to upload it on the server. If true, will never enlarge the image, and will only make it smaller. stretch will resize the image to exactly width and height. cover preserves the aspect ratio, and makes sure the image is at least width wide or height tall. You can use an image from the camera roll or a base64 encoded image. contain will fit the image within width and height, preserving its ratio. Installing and using react-native-image-resizer To resize local image files, we created react-native-image-resizer. Similar to react-native Image's resizeMode: either contain (the default), cover, or stretch. It returns resized images new base64 URI or Blob. Note: This can only be true for JPEG images which are loaded from the file system (not Web). Defaults to false, which means all metadata is lost. If true, will attempt to preserve all file metadata/exif info, except the orientation value since the resizing also does rotation correction to the original image. To set outputPath make sure to add option for rotation too (if no rotation is needed, just set it to 0). If null, resized image will be stored in cache folder. ![]() On iOS, rotation is limited (and rounded) to multiples of 90 degrees. Rotation to apply to the image, in degrees, for android. Height to resize to (see mode for more details)Ĭan be either JPEG, PNG or WEBP (android only).Ī number between 0 and 100. Width to resize to (see mode for more details) Path of image file, or a base64 encoded image string prefixed with 'data:image/imagetype' where imagetype is jpeg or png. The URI can be used directly as the source of an component. The promise resolves with an object containing: path, uri, name, size (bytes), width (pixels), and height of the new file. CreateResizedImage ( path, maxWidth, maxHeight, compressFormat, quality, rotation = 0, outputPath, keepMeta = false, options = ) // Returns a Promise ![]()
