将样式转换图像应用于圆形蒙版 P5.js

如何解决将样式转换图像应用于圆形蒙版 P5.js

目前我将我的风格转移存储在一个名为 Temp 的临时变量中，从那里我想在圆形蒙版中掩盖我的风格转移，使其成为像 Myimage 一样的圆形图像。然而，问题是当我尝试更改与 Temp 变量相关的任何内容时，我收到此错误：未捕获（承诺）TypeError：无法读取未定义的属性“src”。问题是变量在未更改时已定义，但如果发生任何更改，则变为未定义。

任何帮助将不胜感激。

function setup() {
 
     
  canvas = createCanvas(500,500);

  circleMask = createGraphics(128,128);
    
  // load two style transfer models from the models folder
  style1 = ml5.styleTransfer("models/mathura",modelLoaded);
  style2 = ml5.styleTransfer("models/udnie",modelLoaded);
  style3 = ml5.styleTransfer("models/OversoulSpellModel",modelLoaded);
  style4  = ml5.styleTransfer("models/OilPainting",modelLoaded);
    
     circleMask.fill('rgba(0,1)');

  circleMask.circle(64,64,128); //creating a circle mask

  myImage.mask(circleMask._renderer); //using . renderer apperantly fixes the issue of mask not being a function
}


function keypressed() {
  if (key == 'a') {
   console.log("A");
   // myImage  = originalImg; // switch back to original so we can prevent recursive application
    style1.transfer(canvas,function(err,result) {
      
         tempDOMImage = createImg(result.src).hide();
        
      myImage  = tempDOMImage;
          
    });
    
  }else if (key == 'b') {
   
   // myImage  = originalImg; // switch back to original so we can prevent recursive application
    style2.transfer(canvas,result) {
       tempDOMImage = createImg(result.src).hide();
        
      myImage  = tempDOMImage;
    });}
      else if (key == 'c') {
    
   // myImage  = originalImg; // switch back to original so we can prevent recursive application
    style3.transfer(canvas,result) {
       tempDOMImage = createImg(result.src).hide();
      myImage  = tempDOMImage;
    });}
          else if (key == 'd') {
    
   // myImage  = originalImg; // switch back to original so we can prevent recursive application
    style4.transfer(canvas,result) {
       tempDOMImage = createImg(result.src).hide();
      myImage  = tempDOMImage;
    });
    
  }else {
    // we should transfer back
    myImage  = originalImg;
  }
}
