# 网格

定义用于创建和移动对象的网格设置。

要访问此命令...

Open a presentation document, choose LibreOffice - Preferences Tools - Options
- LibreOffice Impress/LibreOffice Draw - Grid.

## 网格

Specifies the settings for the configurable grid on your document pages. This grid helps you determine the exact position of your objects. You can also set this grid in line with the "magnetic" snap grid.

If you have activated the snap grid but wish to move or create individual objects without constraining them, keep the Shift key pressed to deactivate this function for as long as needed.

## 分辨率

### 水平方向

Defines the unit of measure for the spacing between grid points on the X-axis.

### 垂直方向

Defines the grid points spacing in the desired unit of measurement on the Y-axis.

## 线点间隔

### 水平方向

指定 X 轴上网格点之间的中间点数。

### 垂直方向

指定 Y 轴上网格点之间的中间点数。

### 轴数轴同步化

Specifies whether to change the current grid settings symmetrically. The resolution and subdivision for the X and Y axes remain the same.

## 对齐

### 坐标线

Snaps the edge of a dragged object to the nearest snap line when you release the mouse.

也可以使用 与辅助线对齐与辅助线对齐与辅助线对齐
图标来定义此设置，可以在演示文稿或绘图文档的 选项 栏中找到该图标。

### 页边距

Specifies whether to align the contour of the graphic object to the nearest page margin.

光标或图形对象的轮廓线必须位于对齐范围之内。

在演示文稿或绘图文档中，还可以通过选项栏中的与页边距对齐与页边距对齐与页边距对齐
图标来访问此功能。

### 对象框

Specifies whether to align the contour of the graphic object to the border of the nearest graphic object.

光标或图形对象的轮廓线必须位于对齐范围之内。

在演示文稿或绘图文档中，还可以通过选项栏中的与对象边框对齐与对象边框对齐与对象边框对齐
图标来访问此功能。

### 对象点

Specifies whether to align the contour of the graphic object to the points of the nearest graphic object.

仅当光标或图形对象的轮廓线位于对齐范围之内时，才可以这样做。

在演示文稿或绘图文档中，还可以通过选项栏中的与对象点对齐与对象点对齐与对象点对齐
图标来访问此功能。

### 对齐范围

Defines the snap distance between the mouse pointer and the object contour. LibreOffice Impress snaps to a snap point if the mouse pointer is nearer than the distance selected in the Snap range control.

## Constrain Objects

### 在创建或移动对象时

Specifies that graphic objects are restricted vertically, horizontally or diagonally (45°) when creating or moving them. You can temporarily deactivate this setting by pressing the Shift key.

### 较长的图形边

Specifies that a square is created based on the longer side of a rectangle when the Shift key is pressed before you release the mouse button. This also applies to an ellipse (a circle will be created based on the longest diameter of the ellipse). When the Extend edges box is not marked, a square or a circle will be created based on the shorter side or diameter.

### 在旋转时

Specifies that graphic objects can only be rotated within the rotation angle that you selected in the When rotating control. If you want to rotate an object outside the defined angle, press the Shift key when rotating. Release the key when the desired rotation angle is reached.

### 缩小点数

Defines the angle for point reduction. When working with polygons, you might find it useful to reduce their editing points.
