【请问怎么获取图中各图层的状态】

zhuquanmao

请问怎么获取图中各图层的状态。
比如我获取图中各图层的状态，然后把状态保存。再把所有图层全部解锁或打开，然后再执行某个命令后，再把图层恢复到之前的状态。

啥意思？
我是想把状态保存到一个参数里而不只是显示出来哟

Saves a layer state in the current drawing

(layerstate-save layerstatename mask viewport)
Arguments

layerstatename
A string specifying the name of the layer state to save.

mask
An integer sum designating which properties in the layer state are to be restored.

1- Restore the saved On or Off value

2- Restore the saved Frozen or Thawed value

4- Restore the saved Lock value

8- Restore the saved Plot or No Plot value

16- Restore the saved VPVSDFLT value

32- Restore the saved Color

64- Restore the saved LineType

128- Restore the saved LineWeight

viewport
An ename (ads_name) of the viewport whose VPLAYER setting is to be captured. If nil, the layer state will be saved without VPLAYER settings.

Return Values

T if the save is successful; otherwise nil

Examples

(layerstate-save “myLayerState“ 21 viewportId)
T
(layerstate-save “myLayerState“ nil nil)
nil


Restores a layer state into the current drawing

(layerstate-restore layerstatename viewport
[restoreflags])
Arguments

layerstatename
A string specifying the name of the layer to restore.

viewport
An ename (ads_name) of the viewport to which layerstatename should be restored. If viewport is nil, the layer state is restored to model space.

restoreflags
Optional integer sum affecting how the layer state is restored.

1- Turn off all layers not in the restored layer state

2- Freeze all layers not in the restored layer state

4- Restore the layer state properties as viewport overrides (requires viewport to be not a nil value).

Return Values

nil if the layer state does not exist or contains no layers; otherwise, returns a list of layer names.

Examples

(layerstate-restore “myLayerState“ viewportId 5)
(“Layername1” “Layername2“)
