裁剪后为什么我的图像会拉伸? [英] Why does my Image stretch when I crop it?

问题描述

我正在使用以下代码片段来裁剪图像?

I am using the following code snippet in order to crop a image?

   function crop($width,$height) {
       $new_image = imagecreatetruecolor($width, $height);
       imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $this->getWidth(), $this->getHeight(), $width, $height );
       $this->image = $new_image;
   }

在这里，$this->image是原始图像$this->getWidth()，$this->getHeight()保留图片的原始尺寸，其中$width和$height是裁剪区域.

Here, $this->image is the original image $this->getWidth() and $this->getHeight() holds the original dimensions of the picture, where as $width and $height, is the crop area.

但是由于某种原因，裁剪图像被调整了尺寸(我们几乎可以说它被调整了尺寸).

But for some reason, the crop image is resized(we can almost say it is resized).

该如何解决?

推荐答案

好吧，问题出在源代码的尺寸上.给出整个图像的尺寸将重新调整大小，而不是裁剪.

Well, the problem is giving the source dimensions. Giving the dimensions of entire image will re size instead of cropping.

这应该可以解决问题

   function crop($width,$height) {
       $new_image = imagecreatetruecolor($width, $height);
       imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $width, $height );
       $this->image = $new_image;
   }
