ngx-image-zoom NgxImageZoom is inspired by zoom image angular2 and JQuery libraries such as jQuery Zoom and elevateZoom-plus but a pure Angular 5+ implementation of similar concepts. This plugin works with both image URLs and inline images.

Simple VueJS Component for Image Magnifying/Product Zooming
How to make use of it:
Installation:
$ npm install ngx-image-zoom --save
1. From your Angular AppModule:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
// Import the library
import { NgxImageZoomModule } from 'ngx-image-zoom';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
NgxImageZoomModule // <-- Add this line
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
2. Once the library is imported, you can use its components in your Angular app:
<!-- You can now use NgxImageZoom component in app.component.html -->
<h1>
{{title}}
</h1>
<lib-ngx-image-zoom
[thumbImage]=myThumbnail
[fullImage]=myFullresImage
></lib-ngx-image-zoom>Available Options
| Option | Default value | Description |
|---|---|---|
| thumbImage | none | (Required) The smaller version of the image will be shown when there’s no interaction by the user. |
| fullImage | none | The full-resolution version of the image is to be used when zooming. If not supplied thumb image will be used. |
| magnification | 1 | The zoom factor is to be used by default. 1 means we use the fullImage at its actual resolution. |
| zoomMode | ‘hover’ | The mode of zooming to use, is explained in the table below. |
| enableScrollZoom | false | Boolean that toggles if the mouse wheel should be captured when hovering over the image to adjust magnification. |
| scrollStepSize | 0.1 | When using scroll zoom this setting determines how big steps each scroll changes the zoom. |
| enableLens | false | If enabled only a small portion around the mouse cursor will actually magnify instead of the entire image area. |
| lensWidth | 100 | Width of the lens, if enabled. |
| lensHeight | 100 | Height of the lens, if enabled. |
| circularLens | false | Make the lens circular instead of square. This will only look good if width and height are equal. |
| minZoomRatio | baseRatio | The lower limit on how much zoom can be applied with scrollZoom enabled. See below for details. |
| maxZoomRatio | 2 | The upper limit on how much zoom can be applied with scrollZoom enabled. See below for details. |
Zoom modes
| Mode | Description |
|---|---|
| hover | Whenever the mouse cursor moves over the thumbnail it will show the zoomed image until it leaves the thumbnail. |
| click | Similar to hover but it only starts zooming if the user clicks the image. Moving the cursor away from the image disables it again. |
| toggle | A click in the image will zoom at the point of the cursor. Another click will restore the small image. |
| toggle-click | Combination of toggle and click. A click in the image will start zooming. Another click or moving the cursor away from the image will restore the small image. |
| hover-freeze | The first click enables hover mode, the second click freezes the zoomed image where it is, and the third click restores the thumbnail. |
