TImageEnView.LayersArrange
Declaration
procedure LayersArrange(CurIndex, NewIndex: Integer; SwapBackgroundProps: Boolean = False);Description
Rearranges the layer at index, CurIndex, to the position, NewIndex.You can specify LYR_SELECTED_LAYERS (-2) for CurIndex to move all selected layers.
NewIndex can be one of the following:
| >= 0 | The new insertion index |
| IEN_Send_To_Back | The layer will become the new background layer (layer 0) |
| IEN_Send_Backward | The layer will move closer to the background |
| IEN_Bring_Forward | The layer will move closer to the foreground |
| IEN_Bring_To_Front | The layer will become the topmost one (in front of all others) |
If SwapBackgroundProps=True and the background layer (Layer 0) is being moved, the new background layer will inherit the Locked and Selectable properties of the old one (and vice versa).
Note:
◼If the layer has a mask it will be moved too
◼Only a TIEImageLayer can be moved to layer 0 (i.e. background). If you attempt to move a non-image layer to position 0, it will be moved to 1
◼Use LayersArrange to arrange layer order. Use LayersRepositionAll to change the position of layers
Example
// Move the current layer forwardImageEnView1.LayersArrange( ImageEnView1.LayersCurrent, IEN_Bring_Forwards );
// Move selected layers backward
ImageEnView1.LayersArrange( LYR_SELECTED_LAYERS, IEN_Send_Backward );
// Move the selected layers to the back (but not replace the background layer
ImageEnView1.LayersArrange( LYR_SELECTED_LAYERS, 1 );
