The “Smart Object” feature was introduced, which allows the user to scale a layer up without significant loss of quality.
“智能对象”也被引入了,使用户可以在放大一个图层时不出现明显的失真。
Potentially, those filters serve as a policy enforcement layer where the message is first checked from the security and Quality of Service (QoS) standpoints, and then is queued for processing.
这些筛选器可能作为策略强制层,消息首先在这里经过安全和服务质量(QoS)检查,然后排队等待处理。
Automated and centralized code scans that incorporate code quality analysis into existing build processes, thereby adding an additional layer of static analysis quality checks.
自动化并集中代码扫描,将代码质量分析集成到已存在的构建过程中,因此增加了一个静态分析质量检查的额外层。
