class Image Methods defined here:__getattr__(self, name) __init__(self) __repr__(self) convert(self, mode=None, data=None, dither=None, palette=0, colors=256) Convert to other pixel format copy(self) Copy raster data 复制一个新的对象 crop(self, box=None) Crop region from image draft(self, mode, size) Configure image decoder filter(self, filter) Apply environment filter to image fromstring(self, data, decoder_name='raw', *args) Load data to image from binary string 从原始图像数据中加载图像，一般用来从剪切板中获取图像 getbands(self) Get band names getbbox(self) Get bounding box of actual data (non-zero pixels) in image 获取当前图像在实际图片中的范围 getcolors(self, maxcolors=256) Get colors from image, up to given limit getdata(self, band=None) Get image data as sequence object. 获取图像数据列表。如果指定band，就获取这个颜色通道的值得列表 1.print im.getdata()[0] 2.(253,23,34) getextrema(self) Get min/max value getim(self) Get PyCObject pointer to internal image memory getpalette(self) Get palette contents. getpixel(self, xy) Get pixel value 获取每个坐标像素点的RGB值。参数xy格式为(x,y) getprojection(self) Get projection to x and y axes histogram(self, mask=None, extrema=None) Take histogram of image load(self) Explicitly load pixel data. offset(self, xoffset, yoffset=None) (deprecated) Offset image in horizontal and/or vertical direction paste(self, im, box=None, mask=None) Paste other image into region point(self, lut, mode=None) Map image through lookup table putalpha(self, alpha) Set alpha layer putdata(self, data, scale=1.0, offset=0.0) Put data from a sequence object into an image. putpalette(self, data, rawmode='RGB') Put palette data into an image. putpixel(self, xy, value) Set pixel value 设置某坐标像素点值 quantize(self, colors=256, method=0, kmeans=0, palette=None) resize(self, size, resample=0) Resize image 重新设置图像大小 rotate(self, angle, resample=0, expand=0) Rotate image. Angle given as degrees counter-clockwise. 旋转图像 save(self, fp, format=None, **params) Save image to file or stream 保存图像 seek(self, frame) Seek to given frame in sequence file 定位到动画某一帧，一般用于gif格式的文件图片 show(self, title=None, command=None) Display image (for debug purposes only) 现实图像，调用默认的图像浏览器 split(self) Split image into bands 将图像按照RGB分别解析，返回三个Image对象 tell(self) Return current frame number 返回当前帧号 thumbnail(self, size, resample=0) Create thumbnail representation (modifies image in place) 创建缩略图，主要用来修改图像大小和清晰度，以便生产较小的文件 tobitmap(self, name='image') Return image as an XBM bitmap tostring(self, encoder_name='raw', *args) Return image as a binary string transform(self, size, method, data=None, resample=0, fill=1) Transform image transpose(self, method) Transpose image (flip or rotate in 90 degree steps) verify(self) Verify file contents.--------------------------------------------------------------------------------Data and other attributes defined here:format = Nonemodeformat_description = None #功能：blend(im1, im2, alpha) Interpolate between images. 将两张图片混合到一起。参数alpha是im1与im2的混合权重，范围为[0,1]
