本文将介绍如何通过Python中的WriteArray功能将矩阵存储为TIFF影像。 1. 环境准备 首先确保您已经安装了必要的 Python 库。通常,我们使用numpy来生成矩阵,并使用tifffile或imageio等库来存储TIFF文件。可以通过以下命令安装这些库: pipinstallnumpy tifffile 1. 2. 生成矩阵 我们可以使用 numpy 创建一个 2D 矩阵,它...
The imread method returns a NumPy array, img, that contains the image pixel values. We can check out the array’s data type and dimensions as follows: 1 print('Datatype:', img.dtype, '\nDimensions:', img.shape) 1 2 Datatype: uint8 Dimensions: (4000, 6000, 3) The returned...
