compareColorEx (overloaded 1): Compare the colors with multiple coordinate points
Function Description:
Simultaneously compare the colors of a specified number of coordinate points, supporting multicolor, color range, and similarity comparison.
Corresponding JS API:
compareColorEx(multipleColor, sim)
Whether to support multiple devices:
No
Resource Information:
Method | GET |
---|---|
URL | .../devices/:device/screen/colors/color?color=:color&sim=:sim |
Requires authentication? | Yes |
Method Parameters:
Parameter | Type | Required | Description |
---|---|---|---|
device | String | Yes | ID value of the device |
color | String | Yes | The point x, y coordinate and hexadecimal color to be compared, the format is (x coordinate | y coordinate | hexadecimal color); Multiple colors are separated by "|", The color cast is separated by "-", Multiple coordinate point information is separated by ",", such as "100|200|0xffffff|0xaabbcc-0x000000,300|500|0xffffff". |
sim | Float | Yes | Similarity, only works on a single color, invalid for color ranges. For a given single color, if the color of the target pixel in the screen is within a similar range from the specified color, the color is considered to be the same as the target color. The similarity range is [0.0, 1.0] |
Response Parameters:
A JSON string representing an array of objects with the following fields:
Field | Type | Description |
---|---|---|
status | Boolean | Return true for success and null for failure |
value | String | If the value of status is true,an empty string is returned; If the value of status is a null object, an error message or empty string is returned. |
Request Example:
http://localhost:8090/TotalControl/v1/devices/device@1116106541/screen/colors/color?token=270eq7lXQK8bXYsJ&color=100|200|0xffffff|0xaabbcc-0x000000&sim=0.8
Response Example:
If this API executes successfully, it returns:
{
"status": true,
"value": ""
}
If the value of HTTP status code is 200, but the value of status is a null object, it returns:
{
"status": null,
"value": "<Error message>"
}
Example:
Warm tip:
Get the token needed for Total Control script development,see here.
Get the id value of the master device, see here.
RingoJS Example:
// Import the packages
var {request} = require("ringo/httpclient");
var base64 = require("ringo/base64");
// The username and password are separated by a single : and sent on the wire base64 encoded
var userpass = base64.encode("sigma:3D391497");
// First step: Get the API token
var gettoken = request({
method: "GET",
url: "http://localhost:8090/TotalControl/v1/login",
headers: {
"Authorization": userpass
}
});
var ret_token = JSON.parse(gettoken.content);
var token = ret_token.value.token;
print("//The value of token is:" + token);
// Second step: Get the device id value of the master device
var getdevice = request({
method: "GET",
url: "http://localhost:8090/TotalControl/v1/devices/main?token=" + token
});
var device = JSON.parse(getdevice.content).id;
print("//The value of device ID is:"+ device);
// Third step: Execute this REST API
var resp = request({
method: "GET",
url: "http://localhost:8090/TotalControl/v1/devices/" + device + "/screen/colors/color",
data: {
"color": "50|729|0xffffff|0xaabbcc-0x000000,566|729|0xffffff",
"sim": 0.8,
"token": token
}
});
var obj = JSON.parse(resp.content);
var ret = obj.status;
if (ret == true) {
print("//Executed successfully,Return value: \n"+resp.content);
} else if (ret != true & resp.status == 200){
print("An error message is returned: "+resp.content);
} else {
print("This API failed to execute.");
}
The running result of the RingoJS:
If it executes successfully, it will return:
//The value of token is:39D3DX3sRfak7Dls
//The value of device ID is:device@33254183
//Executed successfully,Return value:
{"value":"","status":true}
