Fill image with white color $img-> fill( '#fff') Shrink the image proportionally to fit inside a 500x500 box $img-> best_fit( 500, 500) Shrink the image to the specified height while maintaining proportion (height) $img-> fit_to_height( 200) Shrink the image to the specified width while maintaining proportion (width) $img-> fit_to_width( 320) Trim the image and resize to exactly 100x75 $img-> adaptive_resize( 100, 75) Adjust the orientation if needed (physically rotates/flips the image based on its EXIF 'Orientation' property) $img-> auto_orient() Rotate the image 90 degrees clockwise $img-> rotate( 90) Flip the image horizontally (use 'y' to flip vertically) $img-> flip( 'x') Add 'SimpleImage' => 'Shekarsiri\Simpleimage\SimpleImage' to your 'aliases' array in the app\config\app.php file.Add 'Shekarsiri\Simpleimage\SimpleimageServiceProvider' to your 'providers' array in the app\config\app.php file.Add "shekarsiri/simpleimage": "dev-master" to your /laravel/composer.json.This class requires PHP 5.3 and PHP GD library. Convert between GIF, JPEG, and PNG formats.Overlay one image onto another (watermarking).Desaturate, colorize, pixelate, blur, etc.Resize images (free resize, resize to width, resize to height, resize to fit).It 90 degrees clockwise, shrink it to fit within a 320x200 box, apply a sepiaĮffect, convert it to a GIF, and save it to result.gif. The two lines inside the try block load image.jpg, flip it horizontally, rotate PreferredHeight: (4096 / crop.scale).round(),įinal croppedFile = await ImageCrop.Flip( 'x')-> rotate( 90)-> best_fit( 320, 200)-> sepia()-> save( 'example/result.gif') PreferredWidth: (1024 / crop.scale).round(), Example is illustrated below: final sampledFile = await ImageCrop.sampleImage( When cropped, the image is in higher resolution. Scale up a resolution of the sampled image. In order to produce higher quality cropped image, rely on sampling image with preferred maximum width and height. Once Crop widget is ready, there is a native support of cropping and scaling an image. final sampleFile = await ImageCrop.sampleImage( Prefer to leverage this functionality when displaying images in UI. If it is a square preferredSize can be used to specify both width and height. resample image to get down to 1024x4096 dimension as close as possible. If a large image is to be loaded into the memory, there is a sampling function that relies on a native platform to proportionally scale down the image before loading it to the memory.
final options = await getImageOptions(file: file) ĭebugPrint('image width: $') This is efficient implementation that does not decode nor load actual image into a memory. Read image options, such as: width and height. final permissionsGranted = await ImageCrop.requestPermissions() As a convenience function to request permissions to access photos. area is a rectangle indicating fractional positions on the image to crop from.Īccessing and working with images.scale is a factor to proportionally scale image's width and height when cropped.Using #Ĭreate a widget to load and edit an image: final cropKey = GlobalKey()
Installation #Īdd image_crop as a dependency in pubspec.yaml. Note: This plugin is still under development, some features are not available yet and testing has been limited. Thus if there is a need to save actual cropped image, ensure to copy the file to other location.Īll of the computation intensive work is done off a main thread via dispatch queues on iOS and cache thread pool on Android. Files are stored in cache folders of iOS and Android. The plugin is working with files to avoid passing large amount of data through method channels. Thus it can be composed with other widgets to build custom image cropping experience. The widget renders only image, overlay, and handles to crop an image. A flutter plugin to crop image on iOS and Android.
