## Release ## Release
When your application package meets the release requirements, you can package and build it into an App Pack and release it to the application market on the cloud. The application market verifies the signature of the App Pack. If the signature verification is successful, the application market obtains the HAP files from the App Pack, signs them, and distributes the signed HAP files.

### Example 3
You can apply a spherical effect to a component to make it appear spherized.
```ts
// xxx.ets
@Entry
@Component
struct SphericalEffectExample {
build() {
Stack() {
TextInput({placeholder: "Enter a percentage."})
.width('50%')
.height(35)
.type(InputType.Number)
.enterKeyType(EnterKeyType.Done)
.caretColor(Color.Red)
.placeholderColor(Color.Blue)
.placeholderFont({
size: 20,
style: FontStyle.Italic,
weight: FontWeight.Bold
})
.sphericalEffect(0.5)
}.alignContent(Alignment.Center).width("100%").height("100%")
}
}
```
Below is how the component looks with the spherical effect applied:
![textInputSpherical1](figures/textInputSpherical1.png)
Below is how the component looks without the spherical effect applied:
![textInputSpherical2](figures/textInputSpherical2.png)
### Example 4
You can apply a light up effect to a component.
```ts
// xxx.ets
@Entry
@Component
struct LightUpExample {
build() {
Stack() {
Text('This is the text content with letterSpacing 0.')
.letterSpacing(0)
.fontSize(12)
.border({ width: 1 })
.padding(10)
.width('50%')
.lightUpEffect(0.6)
}.alignContent(Alignment.Center).width("100%").height("100%")
}
}
```
Below is how the component looks with **lightUpEffect** set to **0.6**:
![textLightUp3](figures/textLightUp3.png)
Below is how the component looks with **lightUpEffect** set to **0.2**:
![textLightUp2](figures/textLightUp2.png)
Below is how the component looks without the light up effect applied:

### Example 5
```ts
// xxx.ets
@Entry
@Component
struct LightUpExample {
@State isLunar: boolean = false
private selectedDate: Date = new Date('2028-08-08')
build() {
Stack() {
DatePicker({
start: new Date('1970-1-1'),
end: new Date('2100-1-1'),
selected: this.selectedDate
})
.lunar(this.isLunar)
.onChange((value: DatePickerResult) => {

console.info('select current date is: ' + JSON.stringify(value))

}
}
```

### Example 7
Based on Example 6, change the length values of the pixel stretch effect to negative:
```ts
// xxx.ets
@Entry
@Component
struct PixelStretchExample {
build() {
Stack() {
Text('This is the text content with letterSpacing 0.')
.letterSpacing(0)
.fontSize(12)
.border({ width: 1 })
.padding(10)
.width('50%')
.pixelStretchEffect({top:-10,left:-10,right:-10,bottom:-10 })
}.alignContent(Alignment.Center).width("100%").height("100%")
}
}
```
Below is how the component looks:
![textPixelStretch3](figures/textPixelStretch3.png)
Compared with the original image, the effect drawing is implemented in two steps:
1. The image size is reduced. The resultant size is the original image size minus
the lengths by which the pixels shrink. For example, if the original image size is 100 x 100 and **pixelStretchEffect({top:-10,left:-10,**
**right:-10,bottom:-10})** is set, the resultant size is (100-10-10) x (100-10-10), that is, 8080.
2. Edge pixels are stretched to restore the image to its original size.

# Modal Transition
You can bind a full-screen modal to a component through the **bindContentCover** attribute. Better yet, with the **ModalTransition** parameter, you can apply a transition effect for when the component is inserted or deleted.
> **NOTE**

## Example
### Example 1
```ts
// xxx.ets
@Entry
@Component
struct PixelStretchExample {
build() {
Stack() {
Text('This is the text content with letterSpacing 0.')
.letterSpacing(0)
.fontSize(12)
.border({ width: 1 })
.padding(10)
.width('50%')
.pixelStretchEffect({top:10,left:10,right:10,bottom:10 })
}.alignContent(Alignment.Center).width("100%").height("100%")

```
Below is how the component looks with the pixel stretch effect applied:
![textPixelStretch1](figures/textPixelStretch1.png)
Below is how the component looks without the pixel stretch effect applied:
![textPixelStretch2](figures/textPixelStretch2.png)
A comparison of the preceding two figures shows that, if the length values are positive, the original image is stretched.
### Example 2
Based on Example 1, change the length values of the pixel stretch effect to negative:
```ts
// xxx.ets
@Entry
@Component
struct PixelStretchExample {
build() {
Stack() {
Text('This is the text content with letterSpacing 0.')
.letterSpacing(0)
.fontSize(12)
.border({ width: 1 })
.padding(10)
.width('50%')
.pixelStretchEffect({top:-10,left:-10,right:-10,bottom:-10 })
}.alignContent(Alignment.Center).width("100%").height("100%")
}
}
```
Below is how the component looks:
![textPixelStretch3](figures/textPixelStretch3.png)
Compared with the original image, the effect drawing is implemented in two steps:
1. The image size is reduced. The resultant size is the originial image size minus the lengths by which the pixels shrink. For example, if the original image size is 100 x 100 and **pixelStretchEffect({top:-10,left:-10,right:-10,bottom:-10})** is set, the resultant size is (100-10-10) x (100-10-10), that is, 8080.
2. Edge pixels are stretched to restore the image to its original size.

| bindSheet | isShow: boolean,<br>builder: [CustomBuilder](ts-types.md#custombuilder8),<br>sheetStyle?: [SheetStyle](#sheetstyle10) | Binds a sheet to the component, which can be displayed when the component is touched. **isShow**: whether to display the sheet. Mandatory.<br>**builder**: content of the sheet. Mandatory.<br> **sheetStyle**: height and control bar visibility of the sheet. Optional.

# Spherical Effect
You can apply a spherical effect to a component to make it appear spherized.
> **NOTE**
>
> This attribute is supported since API Version 10. Updates will be marked with a superscript to indicate their earliest API version. This is a system API.
## Attributes
| Name| Type| Description|
| -------- | -------- | -------- |
| sphericalEffect | [number] | Spherical degree of the component.<br>The value ranges from 0 to 1.<br>**NOTE**<br>1. If the value is 0, the component remains unchanged. If the value is 1, the component is completely spherical. Between 0 and 1, a greater value indicates a higher spherical degree.<br>A value less than 0 evaluates to the value **0**. A value greater than 1 evaluates to the value **1**.<br> 2. If a component image is loaded asynchronously, the spherical effect is not supported. For example, the **\<Image>** component uses asynchronous loading by default, which means that **syncLoad** must be set to **true** to apply the spherical effect. However, this setting is not recommended. Asynchronous loading is also used for **backgroundImage**. Therefore, if **backgroundImage** is set, the spherical effect is not supported.<br>3. If the shadow effect is set for a component, the spherical effect is not supported.|
## Example

```ts

@Entry
@Component
struct SphericalEffectExample {

As shown above, the two development paradigms share the UI backend engine and language runtime. The UI backend engine implements the six basic capabilities of ArkUI. The declarative development paradigm does not require the JS Framework for managing the page DOM. As such, it has more streamlined rendering and update links and less memory usage. This makes the declarative development paradigm a better choice for building application UIs. As shown above, the two development paradigms share the UI backend engine and language runtime.
