Edit Selection Mask

编辑选择蒙版

The edit selection mask mode enables you to edit a bitmap selection using the paint tools and filters by means of a temporary mask. There are three main steps involved:

编辑选择掩码模式使您能够通过临时掩码使用绘图工具和过滤器编辑位图选择。主要涉及三个步骤:

• Enable Edit Selection Mask. This bitmap selection changes to a selection mask and the bitmap selection’s dotted line is replaced by a red overlay (the selection mask). 启用编辑选择掩码。这个位图选择变成了一个选择掩码，并且位图选择的虚线被一个红色覆盖层(选择掩码)所取代
• Use the paint tools and filters to edit the selection mask. 使用绘图工具和过滤器编辑选择蒙版
• Disable Edit Selection Mask. The selection mask is converted to a bitmap selection. 禁用编辑选择掩码。选择掩码转换为位图选择

This raises the question: If you start with a bitmap selection and you end up with a bitmap selection, what is the point of this mode? The advantage of the edit selection mask mode is that you can call upon (almost) all the paint tools and filters to create your select. In short, it enables you to create complex selections with relative ease.

这就产生了一个问题: 如果您以位图选择开始，并以位图选择结束，那么这种模式的意义何在？编辑选择蒙版模式的优点是，您可以调用(几乎)所有的绘图工具和过滤器来创建您的选择。简而言之，它使您能够相对容易地创建复杂的选择。

By convention, the selection mask appears as a red overlay. Selected areas are transparent, unselected areas are red. The red areas are slightly transparent to allow you to see through to the image. Even though the mask is shown in red, internally it is actually a grayscale image.

按照惯例，选择蒙版显示为红色叠加。选定的区域是透明的，未选定的区域是红色的。红色区域稍微透明，让你可以看到整个图像。尽管蒙版是红色的，但它内部实际上是一个灰度图像。

Use white to paint a transparent (i.e. selected) region, or black to paint a red (i.e. unselected) region. Use grays for semi-transparency (i.e. partial selection).

使用白色绘制透明(即选定的)区域，或使用黑色绘制红色(即未选定的)区域。使用灰色作为半透明(即部分选择)。

Once you have finished editing the selection mask, disable the mode and the mask will be converted to a bitmap selection.

一旦你完成编辑选择遮罩，禁用模式和遮罩将转换为位图选择。
