compareColorEx (overloaded 2): 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 Two-dimensional array, the point x, y coordinates and hexadecimal color to be compared, the format is [[X coordinate, Y coordinate, hexadecimal color], [X coordinate, Y coordinate, hexadecimal color],...]
Multiple colors are separated by "|", and the range of colors required is separated by "-", such as "0xffffff|0xaabbcc-0x000000, 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=[[3,5,"0x000000"], [4,6,"0x000f00"], [9,225,"0xffffff"]]&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": "[[200,500,'0xffffff|0xaabbcc-0x000000'], [200,400,'0x000f00'], [200,225,'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}

The running result of the python:

If it executes successfully, it will return:

Get the token,Return value:  {'status': True, 'value': {'token': 'lo7ssQ12KgkM6ik7'}}
The value of token is:  lo7ssQ12KgkM6ik7
Get the device id,Return value:  {'id': 'device@33254183'}
The value of device id is:  device@33254183
