Image cropper for Angular

StackBlitz

Installation

npm install ngx-image-cropper --save

Example usage:

Add the ImageCropperModule to the imports of the module which will be using the Image Cropper.

import { NgModule } from '@angular/core';
import { ImageCropperModule } from 'ngx-image-cropper';

@NgModule({
    imports: [
        ...
        ImageCropperModule
    ],
    declarations: [
        ...
    ],
    exports: [
        ...
    ],
    providers: [
        ...
    ]
})
export class YourModule {
}

Add the element to your HTML:

<input type="file" (change)="fileChangeEvent($event)" />

<image-cropper
    [imageChangedEvent]="imageChangedEvent"
    [maintainAspectRatio]="true"
    [aspectRatio]="4 / 3"
    [resizeToWidth]="128"
    format="png"
    (imageCropped)="imageCropped($event)"
    (imageLoaded)="imageLoaded()"
    (loadImageFailed)="loadImageFailed()"
></image-cropper>

<img [src]="croppedImage" />

And add this to your ts file:

imageChangedEvent: any = '';
croppedImage: any = '';

fileChangeEvent(event: any): void {
    this.imageChangedEvent = event;
}
imageCropped(image: string) {
    this.croppedImage = image;
}
imageLoaded() {
    // show cropper
}
loadImageFailed() {
    // show message
}

When you choose a file from the file input, it will trigger fileChangeEvent. That event is then passed to the image cropper through imageChangedEvent which will load the image into the cropper. Everytime you release the mouse, the imageCropped event will be triggerd with the cropped image as a Base64 string in its payload.

API

All inputs are optional. Either the imageChangedEvent or imageBase64 should be set to load an image into the cropper.
