If you want to resize a <code>P5.Graphics</code>, you can just create a new one, then draw the old one to the new one.

<a href="https://alpha.editor.p5js.org/KevinWorkman/sketches/Hyr9iM-xz" rel="nofollow noreferrer">Here</a> is an example:



<pre class="lang-javascript prettyprint-override"><code>var pg;

function setup() {
 createCanvas(1000, 1000);
 pg = createGraphics(100, 100);
 pg.background(100);
 pg.noStroke();
 pg.ellipse(pg.width/2, pg.height/2, pg.width, pg.height);
}

function draw() {
 background(200); 
 image(pg, 0, 0);
}

function mouseClicked(){
 var newPG = createGraphics(mouseX, mouseY);
 newPG.image(pg, 0, 0, newPG.width, newPG.height);
 pg = newPG;
}
</code></pre>

blocks|key|4337961|text|在使用"createGraphics“创建的图形对象上使用resizeCanvas似乎会拉伸图形，而不是调整缓冲区的大小。现在，调整图形对象大小的最好方法是直接设置宽度和高度属性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4337962|//+Some+graphics+object

Using resizeCanvas on a graphics object created with "createGraphics" seems to stretch the graphics rather than resize the buffer.
Right now the best way to resize a graphics object is to simply set the width and height properties directly.

<pre><code>// Some graphics object
let graphics = createGraphics(w,h);

// Now simply resize like this
graphics.width = gWidth;
graphics.height = gHeight;
</code></pre>

As suggested here:
<a href="https://github.com/processing/p5.js/issues/2064#issuecomment-315503533" rel="nofollow noreferrer">https://github.com/processing/p5.js/issues/2064#issuecomment-315503533</a>

In p5.js <code>resizeCanvas(x, y)</code> is a function for p5 objects but if I made a <code>p5.Graphics</code> object, can I resize it with a similar function?

Interestingly, <code>p5.Graphics</code> objects can run <code>resizeGraphics()</code> but nothing happens (including no error) and the height and width remain the same in the console.



<pre class="lang-javascript prettyprint-override"><code>g = createGraphics(50, 50); //creates p5.Graphics
g.resizeCanvas(100, 100); //fails: silently without error
g.resize(100, 100); //fails: resize has not been defined
</code></pre>

Is there another function or would I need to actually extract the cooresponding graphics canvas and call a native javascript function instead?

Thanks!

在p5.js中，resizeCanvas(x, y)是一个用于p5对象的函数，但是如果我创建了一个p5.Graphics对象，我可以用类似的函数调整它的大小吗？有趣的是，p5.Graphics对象可以运行resizeGraphics()，但没有发生任何事情(包括没有错误)，并且控制台中的高度和宽度保持不变。g = cr...
