这是一个Github回购，它有下面的解决方案，一个字体文件和一个用来测试它的图像。
w: The desired width of the image h: The desired height of the image mode: The resizing method: adapt, clip, crop (default), fill and scale adapt: Resize using crop if the resized image retains a supplied percentage of the original image; otherwise fill ...
Path length and accuracy of the anemometers were 60 cm and 1.3%, respectively. Each of the five sets (sets 1 through 5) were mounted on a platform that could be varied in height from the floor level (z = 0) to a height of z = 3.5 m in the vertical direction. In addition, sets...
Returns a resized copy of an image. The size argument gives the requested size in pixels, as a 2-tuple: (width,height). The filter argument can be one ofNEAREST(use nearest neighbour),BILINEAR(linear interpolation in a 2x2 environment),BICUBIC(cubic spline interpolation in a 4x4 environment...
:param factor: A greater than 0 integer or tuple of two integers for width and height separately. :param box: An optional 4-tuple of ints providing the source image region to be reduced. The values must be within ``(0, 0, width, height)`` rectangle. If omitted or ``None``, the...
Creates a new image with the given mode and size. Size is given as a (width, height)-tuple, in pixels. The color is given as a single value for single-band images, and a tuple for multi-band images (with one value for each band). In 1.1.4 and later, you can also use color ...
