DatatypeConverter.printBase64Binary方法是Java中用于将字节数组(byte array)编码为Base64字符串的一个工具方法。它属于javax.xml.bind.DatatypeConverter类,该类提供了一系列在XML绑定操作中常用的数据类型转换功能。Base64编码是一种基于64个可打印字符来表示二进制数据的方法,常用于在HTTP和MIME协议中传输编码后的二...
This Idea has been implemented in ArcGIS Pro 3.2. Specifically, the ability to toggle printer margins on/off, while possible in previous releases of Pro, was added to the Print pane to make previewing the margins more discoverable and easier to work with. We also added the ability to display...
