Python ByteArrayToImagePython Gtk+从字节数组恢复图像 在Python编程语言中,处理图像数据是一项常见的任务。在某些情况下,我们可能需要将图像数据存储为字节数组(byte array),然后在需要时从中恢复图像。这在例如网络传输、数据库存储或使用GUI库如Gtk+进行显示时特别有用。本教程将详细介绍如何在Python中使用Gtk+库从...

在这个步骤中,我们将使用ByteArrayOutputStream将图像转换为字节数组,这可以让我们创建一个流。以下是相关代码: importjavax.imageio.ImageIO;importjava.awt.image.BufferedImage;importjava.io.ByteArrayOutputStream;importjava.io.IOException;importjava.io.InputStream;// 步骤2:将图像转换为流InputStreamimageToInput...
