fromPILimportImage# 1. 打开指定路径的图片文件image_path='example.jpg'# 把这里替换成你想转换的图片路径image=Image.open(image_path)# 2. 以二进制模式打开图片文件withopen(image_path,'rb')asimg_file:img_data=img_file.read()# 读取文件为二进制数据# 3. 将二进制数据转换为bytearrayimg_bytearray...
接下来我们可以编写代码: fromPILimportImageimportiodefimage_to_bytes(image_path):# 打开图像文件withImage.open(image_path)asimg:# 创建一个 BytesIO 对象img_byte_arr=io.BytesIO()# 将图片保存到 BytesIO 对象img.save(img_byte_arr,format=img.format)# 获取字节数据img_byte_arr=img_byte_arr.getv...
你可以使用以下代码将字节流转换成图像：```pythonimport cv2importnumpyas npdef bytes_to_image(byte_...
from PIL import Image import io 从文件加载图片 image = Image.open('example.jpg') 将图片转换为字节数据 byte_arr = io.BytesIO() image.save(byte_arr, format='JPEG') image_bytes = byte_arr.getvalue() 从字节数据加载图片 image_stream = io.BytesIO(image_bytes) loaded_image = Image.open(...
fromPILimportImageimage_width,image_height=30,30# 填充占位数据image_bytes=bytearray([0x70,0x70,0x70])*image_width*image_heighti=0# 设置颜色渐变foryinrange(image_height):forxinrange(image_width):image_bytes[i]=int(255.0*(x/image_width))# Rimage_bytes[i+1]=int(255.0*(y/image_height)...
im=Image.fromarray(result*255.0) im.convert('L').save("1.jpg",format='jpeg') 这是我得到的128*256大小的灰度图 二、利用CV库 看这篇博客,这个方法和利用PIL库有异曲同工之处 主要步骤 1.生成普通python数组(bytearray(),os.urandom())
ByteArrays can also be used as a buffer for sending data from your Python script to a Python library for data processing. For example, say you are writing an image recognition library that processes images. As we know everything in computers is basically stored in 0’s and 1’s. You ca...
from PIL import Image import io def image_to_byte_array(image: Image) -> bytes: # BytesIO is a fake file stored in memory imgByteArr = io.BytesIO() # image.save expects a file as a argument, passing a bytes io ins image.save(imgByteArr, format=image.format) # Turn the BytesIO...
