步骤1:安装 Pillow 库 首先,你需要安装 Pillow 库。如果你还没有安装它,可以通过以下命令来安装: pip install Pillow 步骤2:导入所需模块 在你的 Python 脚本中,导入 Pillow 库的 Image 模块来进行图片处理。 from PIL import Image 步骤3:加载两张图片 我们需要加载两张图片。一张是背景图,另一张是需要放置...
在Pillow库中,图像缩放可以通过resize()函数来实现。该函数接受一个元组作为参数,该元组包含了新的图像尺寸。例如,如果我们想将一张图片缩小到宽度为200像素,高度按比例缩放,我们可以这样调用resize()函数:resize((200, int(image.height * 200 / image.width)))。 除了指定新的图像尺寸外,resize()函数还可以接受...
hsize = int((float(img.size[1]) * float(wpercent))) img = img.resize((basewidth, hsize), Image.ANTIALIAS) img.save('resized_image.jpg') These few lines of Python code resize an image (fullsized_image.jpg) using Pillow to a width of 300 pixels, which is set in the variablebase...
Pillow 2.7++ Python 2.7/3.4 Introduction The following functions are supported: resize_cropcrop the image with a centered rectangle of the specified size. resize_coverresize the image to fill the specified area, crop as needed (same behavior asbackground-size: cover). ...
2、Pillow 是 PIL的对Python3支持的一个分支,对Python2兼容 from PIL import Image img = Image.open('xxx.png') img1=img.resize((550,260))#图片尺寸缩放w,h image = np.array(img,dtype=np.float32) "image = np.array(image)默认是uint8,这时PIL格式转化为numpy,数据维度变化" ...
image = Image.open('/example/path/to/image/file.jpg/') image.thumbnail((80, 80), Image.ANTIALIAS) image.save('/some/path/thumb.jpg', 'JPEG', quality=88) Solution 2: If you have used Pillow instead of PIL, you might find the information on the official Pillow website useful. ...
We first open the image using theImage.openfunction from the Pillow library. We get the original width and height of the image using theimage.sizeattribute. We check if either the width or height is greater thanmax_size. If eitherwidthorheightis greater thanmax_size, we calculate the new ...
这篇文章是The Fastest Image Resize Part0的DeepL机翻+人工复核。其作者Alex Karpinsky系Pillow-SIMD的开发者。 前言 我为现代x86架构处理器设计了最快的图像缩放算法实现。我想与大家分享我的经验,希望能给予那些同样从事算法优化的人一些启发。 尽管本文主要面向开发人员,但我还是力求简单明了。不过,我喜欢技术细节...
ThePILis an acronym for Python Imaging Library, which contains some modules for image processing. We can resize an image using theresize()method of theImageclass available in thePILmodule. First, install thePILmodule: pip install pillow
Hi there, I've been trying to understand how images are resized (specifically downscaled) when using Image.ANTIALIAS. I understand that a Lanczos kernel is involved, but not exactly sure how. For example, if an image is being downscaled ...
