Question

我必须使用此代码裁剪50X50的图像：

import {async,TestBed,inject}from '@angular/core/testing';
import {Response,ResponseOptions, XHRBackend } from '@angular/http';
import {    MockBackend,    MockConnection}from '@angular/http/testing';
import {    HttpModule}from '@angular/http';
import {    Router, ActivatedRoute}from '@angular/router';
import {    MockRouter}from '../mock/router.mock';
import {    usersData}from '../data/mockData/users';
import {    UsersComponent}from './list-users.component';
describe('list-users.component.ts', () => {
beforeEach(() => {
        TestBed.configureTestingModule(
            {
                declarations: [UsersComponent],
                imports: [HttpModule, DevExtremeModule],
                providers: [MockBackend, BaseRequestOptions,
                    { provide: XHRBackend, useClass: MockBackend },
                    { provide: Router, useClass: MockRouter },
                    { provide: ActivatedRoute, useClass: MockRouter },
                    {
                        provide: Http, useFactory: (backendInstance: MockBackend, defaultOptions: BaseRequestOptions) => {
                            return new Http(backendInstance, defaultOptions);
                        },
                        deps: [MockBackend, BaseRequestOptions]
                    },
                    { provide: AuthHttp, useExisting: Http, deps: [Http] }
                ]
            });
    });

    it('should instantiate UsersComponent', () => {
        const fixture = TestBed.createComponent(UsersComponent);
        let compInstance: UsersComponent = fixture.componentInstance;
        expect(compInstance instanceof UsersComponent).toBe(true, 'should create UsersComponent');
    });

    it('It checks loadUserList() is binding datasource',
        async(inject([XHRBackend],
                (mockBackend: MockBackend) => {
                mockBackend.connections.subscribe(
                    (connection: MockConnection) => {
                    connection.mockRespond(new Response(
                            new ResponseOptions({
                                body: usersData
                            })));
                });

                const fixture = TestBed.createComponent(UsersComponent);
                let instance: UsersComponent = fixture.componentInstance;
                instance.instance.loadUserList();;
                expect(instance.userData.length).toEqual(usersData.length);
                expect(instance.userData).toBe(usersData);
            })));
}

现在我需要获得相对于原始图像的这个裁剪pic的坐标。怎么做？

Answer 1

您已使用这些坐标裁剪图像。

[starty：starty + cropy，startx的：运行startx + cropx]

如何获取相对于原始图像的裁剪图像的坐标？
