TODO: - support record arrays in rgb2qimage (i.e.def array2PIL( arr, size): mode = 'L' arr = arr.

create a new Surface that shares data inside a bytes buffer The image module contains functions for loading and saving pictures, as well as transferring Surfaces to formats usable by other packages.此外，使用frombuffer, fromstring, fromfile等函数可以从. This book will give you a solid foundation in NumPy arrays and universal functions.

High performance calculations can be done easily with clean and efficient code, and it allows you to execute complex algebraic and mathematical computations in no time.

NumPy has the ability to give you speed and high productivity.

Structured dtype objects can be indexed with multiple fields names This returns a (numerator, denominator) pair, which can be used to construct a fractions.Fraction. Floating point scalars implement as_integer_ratio to match the builtin float.

of new arbitrary-shape arrays from NumPy-like libraries when such an array is used as the prototype.

It is a library consisting of multidimensional array objects and a collection of routines for processing of array. The “strides” describe how that data is arranged to look like an array of more dimensions: 2D, 3D, 4D etc. numpy arrays are really wrappers about “strided data” This means that there is a single linear block of memory with the values in it.Use frombuffer instead waveData = np.fromstring(strData, dtype=np.short) # 将字符串转化为int.Here is the code exrFile = OpenEXR.InputFile('fallroad_0001.exr') header = exrFile. I am exporting a scene to OpenEXR multichannel (with no compression and FULL format) and read it back using Python.
