pil resize
I love Python, and I've been learning it for a while now. Some time ago, I wrote a Python script where I needed to resize a bunch of images while at the same time keeping the aspect ratio (the proportions) intact. So I looked around and found the PIL,Open, rotate, and display an image (using the default viewer)¶. from PIL import Image im = Image.open("bride.jpg") im.rotate(45).show(). The following script creates nice 128x128 thumbnails of all JPEG images in the current directory. ,Open, rotate, and display an image (using the default viewer)¶. from PIL import Image im = Image.open("bride.jpg") im.rotate(45).show(). The following script creates nice 128x128 thumbnails of all JPEG images in the current directory. ,Parameters: im – image to composite over this one; dest – Optional 2 tuple (top, left) specifying the upper left corner in this (destination) image. source – Optional 2 (top, left) tuple for the upper left corner in the overlay source image, or 4 tuple (t, Define a maximum size. Then, compute a resize ratio by taking min(maxwidth/width, maxheight/height) . The proper size is oldsize*ratio . There is of course also a library method to do this: the method Image.thumbnail . Below is an (edited) example from t, resize() returns a resized copy of an image. It doesn't modify the original. The correct way to use it is: img = img.resize((150, newheight), image.ANTIALIAS). source. I think what you are looking for is the ImageOps.fit function. From PIL docs: Imag, 今天突然发现自己缩放程序有问题，图片缩放尺度大了就会失真。小编一直使用的是缩小的功能，图片缩小整体0.7还可以，整体缩小0.65就会有部分的信息丢失，怎奈我的图都是大图，没办法只能寻找解决方法。 原来代码img = img.resize((width, height)) 后来找资料发现 PIL带ANTIALIAS滤镜缩放结果所以将代码改 ..., #!/usr/bin/python from PIL import Image import os, sys path = "/root/Desktop/python/images/" dirs = os.listdir( path ) def resize(): for item in dirs: if os.path.isfile(path+item): im = Image.open(path+item) f, e = os.path.splitext(path+item) i, Image.resize resizes to the dimensions you specify,. Image.resize([256,512],PIL.Image.ANTIALIAS) # resizes to 256x512 exactly. Image.thumbnail resizes the the max input dimensions (width and height). Image.thumbnail([512,512],PIL.Image.ANTIALIAS).
