"Photoshop_认证考试题(答案已校)汇编.pdf" 这篇文档是针对Photoshop认证考试的一份习题集，包含了多项选择题，涵盖了软件的多个功能和使用技巧。以下是根据题目内容提炼出的相关知识点： 1. **滤镜**：滤镜在Photoshop中用于图像处理和特效添加。题目提到了"滤镜>杂色"可以减少渐变中的色带，这是为了消除颜色过渡不平滑产生的色带现象，提高图像质量。 2. **图层剪贴路径**：剪贴路径是一种矢量形状，它可以精确地定义图像的一部分。它不同于图层蒙版，因为剪贴路径不依赖于图像分辨率，可以转换为图层蒙版，并且可以通过钢笔工具或图形工具创建。 3. **打印设置**：如果打印出来的图像无法完全覆盖文件的所有内容，可以通过调整图像尺寸、页面设置或使用其他排版软件如Pagemaker来解决。例如，选择“缩到和打印范围相同大小”可以在Pagemaker中确保内容完整打印。 4. **路径和Illustrator的关系**：Photoshop中的路径和Illustrator中的路径虽然都是矢量形式，但并不完全相同。Photoshop中的路径可以转换为浮动的选择范围，而Illustrator中的路径处理更为专业，更适合矢量图形设计。 5. **GIF优化**：GIF格式支持透明背景，优化时可以调整"杂边"颜色来改善在特定背景下的显示效果。"杂边"的颜色设定会影响文件大小，因为它涉及到额外的颜色信息。 6. **历史记录**：在Photoshop中，历史记录可以记录操作步骤，方便回溯。历史记录画笔可以用来恢复或修改某个特定步骤的状态，而橡皮擦工具、填充命令和重做/还原命令则提供了不同的编辑和恢复选项。 7. **画笔设置**：在创建新画笔时，可以调整画笔的直径、硬度和间距等参数，以满足不同绘画需求。颜色设置通常是在实际绘画时选择，而非创建画笔时设定。 8. **GIF格式特点**：GIF是一种压缩格式，适合有单调颜色和清晰细节的图像。减少文件中的颜色数量可以减小文件大小，而色彩值8表示256种颜色，是2的8次方。 9. **Brushes（画笔）**：未提供具体题目，但通常在Photoshop中，画笔工具是用于绘制和编辑图像的重要工具，可以自定义其大小、形状、硬度、颜色等属性。 这些知识点展示了Photoshop在图像编辑、处理、优化和输出方面的多样性和灵活性，对于准备Photoshop认证考试的考生来说，理解并掌握这些概念和技术至关重要。

这是因为在 SQL 查询中使用了小写的列名，导致返回结果中的列名也是小写的。如果想要返回大写的列名，可以在 SQL 查询中使用 AS 关键字来指定别名，例如： ``` SELECT u.org_id AS orgId, u.user_id AS userId, ......
