为什么ImageResizer自动旋转图像垂直拍摄并显示水平

Question

您好我使用ImageResizer上传了图片 使用此代码 var instructions = new ImageResizer.Instructions { Width = Convert.ToInt32(Newwidth), Height = Convert.ToInt32(Newheiht), Format = "jpg", Mode = ImageResizer.FitMode.Crop,
Scale = ImageResizer.ScaleMode.Both, };
File.InputStream.Seek(0, SeekOrigin.Begin); ImageResizer.ImageJob i = new ImageResizer.ImageJob(File, Filepath, instructions); i.CreateParentDirectory = false; i.Build();

我尝试过使用

AutoRotate = true

我仍然将图像旋转到horizo​​ntall

我也试过Rotate=90 图片旋转并丢失了比例，这是旋转

后的样子

调整大小的roteted图片将其更改为width = 296 height = 437而不是height = 296 width = 437

图像是使用三星galaxy 3购买时调整大小并上传它显示在地平线

这是拍摄的原始照片：

以上是上传后的显示方式：

尝试自动旋转属性“True”;它对我有用。

import { Component, Injectable, OnInit, OnDestroy } from '@angular/core';

import {BehaviorSubject} from "rxjs/BehaviorSubject";
import {Subscription} from 'rxjs/Subscription';

@Injectable()
class ProcessService {
  private _processedMsgSrc: BehaviourSubject<string> = new BehaviorSubject<string>("");
  processedMsg = this._processedMsgSrc.asObservable();
  process(msg) {
    this._processedMsgSrc.next("Processed: \""+msg+"\"");
  }
}

@Component({
  selector: 'output',
  template: '<span>{{output}}</span>'
})
class OutputComponent implements OnInit, OnDestroy {
  output:string;
  private _subscription:Subscription;
  constructor(public processService: ProcessService){}
  ngOnInit() {
    this.subscription = this.processService.processedMsg.subscribe(
      msg => this.output = msg
    );
  }
  ngOnDestroy() {
    // stop the subscription when the component is destroyed
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-app',
  directives: [OutputComponent],
  providers: [ProcessService],
  template: `
    <input class="input" type ="text" [(ngModel)]="text" (keyup.enter)="process(text)">
    <br>
    <output></output>
  `
})
export class AppComponent {
  text:string;
  constructor(private processService: ProcessService){}
  process(text){
    this.processService.process(text);
  }
}
