# System Brightness Customization
## Overview
### Introduction
By default, the system brightness of OpenHarmony ranges from **0** to **255** (**0** indicates the minimum luminance and **255** the maximum). It is applicable to the entire system and all application windows. Due to hardware restrictions, some display devices are unable to support the system brightness range. To address this issue, OpenHarmony provides the function of customizing the system brightness range. This way, you can adjust the system brightness range based on the hardware specifications of the display devices.
### Basic Concepts
**System brightness**
Global brightness of OpenHarmony. The customized brightness range is effective for all application windows.
**Window brightness**
Brightness of an application window. The customized brightness range is effective only for this application window. After a brightness is specified for an application window, its brightness is not affected by the system brightness.
### Constraints
The [sysparam](./subsys-boot-init-sysparam.md) module of OpenHarmony provides an easy-to-use key-value pair access interface for system services to configure service functions based on their own system parameters. The customization of the system brightness range is dependent on this feature.
## How to Develop
### Setting Up the Environment
**Hardware requirements:**
Development board running the standard system, for example, the DAYU200 or Hi3516D V300 open source suite.
**Environment requirements:**
For details about the requirements on the Linux environment, see [Quick Start](../quick-start/Readme-EN.md).
### How to Develop
1. In the target directory, create a target folder by referring to the [default brightness value configuration folder](https://gitee.com/openharmony/powermgr_display_manager/tree/master/service/etc). The file format is as follows:
```text
etc
├── BUILD.gn
├── display.para
├── display.para.dac
```
2. Write the customized **display.para** file by referring to the [**display.para** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/service/etc/display.para) in the default brightness range configuration folder. Include the customized brightness thresholds, for example, **max=150**, **default=75**, and **min=50**, into the file:
```shell
# Brightness limits is 0-255.
const.display.brightness.min=50
const.display.brightness.default=75
const.display.brightness.max=150
```
3. Write the customized **display.para.dac** file by referring to the [**display.para.dac** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/service/etc/display.para.dac) in the default brightness range configuration folder, so as to grant the permission required to access the customized configuration.
```shell
const.display.brightness.="foundation:foundation:444"
```
4. Write the customized **BUILD.gn** file by referring to the [**BUILD.gn** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/service/etc/BUILD.gn) in the default brightness range configuration folder. Then, put the **display.para** and **display.para.dac** files to the **/vendor/etc/param** directory. For example:
```shell
import("//base/powermgr/display_manager/displaymgr.gni")
import("//build/ohos.gni")
## Install display.para to /vendor/etc/param/display.para
ohos_prebuilt_etc("display.para") {
source = "display.para"
relative_install_dir = "param"
install_images = [ chipset_base_dir ]
part_name = "${displaymgr_part_name}"
subsystem_name = "powermgr"
}
ohos_prebuilt_etc("display.para.dac") {
source = "display.para.dac"
relative_install_dir = "param"
install_images = [ chipset_base_dir ]
part_name = "${displaymgr_part_name}"
subsystem_name = "powermgr"
}
group("param_files") {
deps = [
":display.para",
":display.para.dac",
]
}
```
5. Write the customized **bundle.json** file by referring to the [**bundle.json** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/bundle.json) in the default brightness range configuration folder, so as to compile the **BUILD.gn** file.
```shell
"service_group": [ "//base/powermgr/display_manager/service/etc:param_files" ]
```
In the preceding code, **//base/powermgr/display_manager/service** indicates the directory of the created folder, and **etc** indicates the folder name.
6. Build the customized version by referring to [Quick Start](../quick-start/Readme-EN.md). The following command uses DAYU200 as an example:
```shell
./build.sh --product-name rk3568 --ccache
```
7. Burn the customized version to the DAYU200 development board.
### Debugging and Verification
1. After startup, run the following command to launch the shell command line:
```shell
hdc shell
```
2. Run the following command to check the console output:
```shell
hidumper -s 3308 -a -a
```
3. Check the console output for the customized system brightness thresholds.
The default system brightness thresholds are as follows:
```shell
----------------------------------DisplayPowerManagerService---------------------------------
DISPLAY POWER MANAGER DUMP:
Display Id=0 State=2 Discount=1.000000 Brightness=102
DeviceBrightness=102
Support Ambient Light: FALSE
Auto Adjust Brightness: OFF
Brightness Limits: Max=255 Min=5 Default=102
```
Assume that the system brightness thresholds are set to **Max=150 Min=50 Default=75**. The console output is as follows:
```shell
# cd vendor/etc/param
# ls
display.para thermal.para usb.para.dac
display.para.dac thermal.para.dac
# cat display.para

# Brightness limits is 0-255.
const.display.brightness.min=50
const.display.brightness.default=75
const.display.brightness.max=150#
#
# cd
# hidumper -s 3308 -a -a
-------------------------------[ability]-------------------------------
----------------------------------DisplayPowerManagerService---------------------------------
DISPLAY POWER MANAGER DUMP:
Display Id=0 State=0 Discount=1.000000 Brightness=75
DeviceBrightness=75
Support Ambient Light: FALSE

```
4. Set the system brightness thresholds to the customized values.
## Reference
For details about how to write the configuration file during system brightness customization, refer to the [default brightness range configuration file](https://gitee.com/openharmony/powermgr_display_manager/tree/master/service/etc).
Default configuration:
```shell
# Brightness limits is 0-255.
const.display.brightness.min=5
const.display.brightness.default=102
const.display.brightness.max=255
```

# Globalization Subsystem Changelog
## cl.resourceManager.1 Change in the Meaning of the Return Value for the API Used to Obtain the rawfile Descriptor
Changed the meaning of the return value for the API used to obtain the rawfile descriptor after the non-decompression feature is added in this version. The change in the meaning of the return value, namely, **descriptor: RawFileDescriptor {fd, offset, length}**, is described as follows:
**Before change:**
**fd**: file descriptor for accessing the rawfile.
**offset**: offset for accessing the rawfile. In this case, the value is **0**.
**length**: size of the rawfile to access.
**After change:**
**fd**: file descriptor for accessing the HAP where the rawfile is located.
**offset**: offset of the accessed rawfile relative to the HAP.
**length**: size of the rawfile to access.
**Change Impact**
In versions earlier than 4.0.2.2, the rawfile can be accessed only through **fd**. In version 4.0.2.2 or later, the rawfile can be accessed only through **{fd, offset, and length}**.
**Key API/Component Changes**
| **Original API** |
| ---------------- |
| getRawFd(path: string, callback: AsyncCallback\<RawFileDescriptor>): void |
| getRawFd(path: string): Promise\<RawFileDescriptor> |
| getRawFileDescriptor(path: string, callback: AsyncCallback\<RawFileDescriptor>): void|
| getRawFileDescriptor(path: string): Promise\<RawFileDescriptor>|
||
**Sample Code**
The following is an example of calling the **getRawFd** API:
```
try {
this.context.resourceManager.getRawFd("test.ogg", (error, value) => {
if (error != null) {
console.log(`callback getRawFd failed error code: ${error.code}, message: ${error.message}.`);
} else {
let fileDescriptor = {
fd = value.fd,
offset = value.offset,
length = value.length
}
this.avPlayer.fdSrc(fileDescriptor); // Take the audio player as an example. When calling fdSrc, pass fileDescriptor in addition to fd.
}
});
} catch (error) {
console.error(`callback getRawFd failed, error code: ${error.code}, message: ${error.message}.`)
};
```
