截图
前言
截图是为了给潜在的用户展示软件的样子和感觉，在运行软件时让用户有个印象来期待。所以，截图应该记录常用的环境和应用，给用户以标准的硬件配置。
准则
- 如果不是中文截图，请把语言设为相应的语言
- 把图片存为 PNG 格式
- 最好使用默认设置（图标、配色、风格、窗口、应用设置等等）
- 最好使用 compositing (Desktop Effects module in 系统设置），如果你的显卡不支持 compositing 那就别用了，别担心。
- 最好使用 9 点的 “Liberation Sans” 字体
- 如果截图展现的是部分桌面，最好使用 plasma 的默认背景。如有可能，给图片留个边（约20像素），这样就不像把窗口阴影给去了
- 如果是张中文截图，请用原来的英文文件名，外加 “zh-cn” 这个语言码
- 如果更新已有截图，请用相同的文件名，这样就自动更新了
步骤
下面这个例子用了 KSnapshot，不过别的截屏应用也可以。
- Start KSnapshot
- Choose a Capture mode (1) from the following:
- Current Screen (only visible on a multi-screen environment)
- Everything on the single screen is captured, usually used for desktop screenshots.
- Full Screen
- This works differently, depending on whether you have a single screen or a multi-screen environment. For single screen users it captures everything currently on the screen. Multi-screen users will see it capture all screens into a single window.
- Window Under Cursor
- The content of an applications or dialog window is captured. usually used for application screenshots. Preferably, check the Include window decorations option (2).
- Region
- Only a region to be defined later is captured.
- Click on (3).
- Full Screen
- Current Screen
- Window Under Cursor
- Click anywhere on the screen to take the snapshot.
- Region
-
- Use the mouse to draw a rectangle around the region to be captured (for example around a window).
- Strike the Enter key or click on or double click in the region to take the snapshot.
- Click on (4).
- Browse to the location you want to save the image, give it a name (name.png) and click on
提示和技巧
- The option (5) makes KSnapshot wait a given amount of time (given in seconds) before taking the snapshot. This can be useful in many situations, for example when taking screenshots of drop-down menus
- It's often useful to create a separate user for taking screenshots to ensure a standard look with the default settings.
- Use in the wallpaper settings to get a white background.
