Image

<Image> is a UI component for rendering images. Images can be referenced by URL, resource URL (res://), base64 string, font resource (font://), ImageSource, and ImageAsset.

<Imagesrc="~/assets/logo.png"height="60" />

<Imagesrc="~/assets/logo.png"height="60" />

<imagesrc="~/assets/logo.png" />

<imagesrc="~/assets/solid.png"height={60} />

<imagesrc="~/assets/logo.png"height="60"></image>

<Imagesrc="~/assets/logo.png"height="60" />

Examples ​

Displaying images from App_Resources ​

To display images from platform specific locations (App_Resources/Android/drawable-XXX/, or App_Resources/iOS/) prefix the source with res://.

<Imagesrc="res://icon" />

Displaying images from the src/assets directory ​

By default all assets placed in the src/assets directory (create the directory if it's not present) will be copied to the correct native platform location to be bundled with the app. To reference these images, prefix them with the ~ character, which is an alias pointing to the src folder.

<Imagesrc="~/assets/logo.png" />

Displaying images from URLs ​

Images can be displayed from remote URLs. Depending on the software version of the device, insecure URLs may be blocked (http://), it's recommended to always use secure URLs (https://).

<Image
src="https://art.nativescript.org/logo/export/NativeScript_Logo_Blue_White.png"
/>

Displaying base64-encoded images ​

Images can be displayed from base64 encoded strings.

<Imagesrc="data:Image/png;base64,iVBORw..." />

Rendering font icons as images ​

Font symbols can be rendered as an image by prefixing the source with font:// and setting the correct font-family via eg. a CSS class:

<Imagesrc="font://&#xf004;"class="fas" />

.fas {
font-family: 'Font Awesome';
/* ... */
}

Using SF Symbols on iOS (8.8+) ​

Images can also be used to display SF Symbols on iOS by using the sys:// prefix along with the symbol name. These also support iosSymbolEffect for animated effects as well as iosSymbolScale with a possible value of small|medium|large;

<GridLayoutrows="auto,auto"columns="*,*">
 <image
src="sys://photo.on.rectangle.angled"
tintColor="green"
[iosSymbolEffect]="symbolBounceEffect"
 />

 <image
col="1"
src="sys://photo.on.rectangle.angled"
tintColor="green"
[iosSymbolEffect]="symbolBounceEffect"
iosSymbolScale="small"
 />

 <image
row="1"
src="sys://photo.on.rectangle.angled"
tintColor="green"
[iosSymbolEffect]="symbolBounceEffect"
iosSymbolScale="medium"
 />

 <image
row="1"
col="1"
src="sys://photo.on.rectangle.angled"
tintColor="green"
[iosSymbolEffect]="symbolBounceEffect"
iosSymbolScale="large"
 />
</GridLayout>

import { ImageSymbolEffects } from'@nativescript/core'

constsymbolBounceEffect= ImageSymbolEffects.Bounce

This demonstrates using various built-in presets for effects and also using the iosSymbolScale property which is useful when you apply affects so the animation doesn't exceed the bounds of it's Image container (as can be seen in the top left usage in the video).

Custom Symbol Effects ​

You can also create custom effects using the full expansive iOS symbol API, for example:

import { ImageSymbolEffect } from'@nativescript/core'

consteffect=newImageSymbolEffect(NSSymbolBounceEffect.effect())
effect.options =
 NSSymbolEffectOptions.optionsWithSpeed(2).optionsWithRepeatCount(6)
effect.completion= (context) => {
 console.log('effect completed!', context)
}
constcustomSymbolEffect= effect

<image
src="sys://heart.fill"
tintColor="red"
[iosSymbolEffect]="customSymbolEffect"
/>

Props ​

src ​

src: string | ImageSource | ImageAsset

Gets or sets the source.

A string can be a http://, https://, res://, font:// or an absolute path (eg. ~/assets/image.png).

See ImageSource and ImageAsset.

imageSource ​

imageSource: ImageSource

Gets or sets the source from an ImageSource instance.

See ImageSource.

tintColor ​

tintColor: Color | string

Sets a color to tint the image.

See Color.

stretch ​

stretch: ImageStretchType // "none" | "aspectFill" | "aspectFit" | "fill"

Gets or sets the way the image is resized to fill its allocated space.

See ImageStretchType

iosSymbolEffect (8.8+) ​

iosSymbolEffect: ImageSymbolEffect | ImageSymbolEffects

Gets or sets the effect of the SF Symbol. You can create your own custom ImageSymbolEffect or use presets defined from ImageSymbolEffects, for example:

exportenumImageSymbolEffects {
Appear='appear',
AppearUp='appearUp',
AppearDown='appearDown',
Bounce='bounce',
BounceUp='bounceUp',
BounceDown='bounceDown',
Disappear='disappear',
DisappearDown='disappearDown',
DisappearUp='disappearUp',
Pulse='pulse',
Scale='scale',
ScaleDown='scaleDown',
ScaleUp='scaleUp',
VariableColor='variableColor',
Breathe='breathe',
BreathePlain='breathePlain',
BreathePulse='breathePulse',
Rotate='rotate',
RotateClockwise='rotateClockwise',
RotateCounterClockwise='rotateCounterClockwise',
Wiggle='wiggle',
WiggleBackward='wiggleBackward',
WiggleClockwise='wiggleClockwise',
WiggleCounterClockwise='wiggleCounterClockwise',
WiggleDown='wiggleDown',
WiggleForward='wiggleForward',
WiggleUp='wiggleUp',
WiggleLeft='wiggleLeft',
WiggleRight='wiggleRight',
}

Keep in mind that some are only iOS 17 or 18 and above.

iosSymbolScale (8.8+) ​

iosSymbolScale: number

Gets or sets the scale of the SF Symbol.

loadMode ​

loadMode: 'sync'|'async'

Gets or sets the loading strategy for the images.

Default value: async.

Valid values:

• sync - blocks the UI if necessary to display immediately. Only recommeded for small images like icons.
• async - loads in the background, the image may appear with a short delay, good for large images.

Note: When loading images from the web, they are always loaded async.

...Inherited ​
