TImageEnLayerMView


Declaration

TImageEnLayerMView = class(TIECustomMView);


Description

The TImageEnLayerMView component is a descendent of TImageEnMView, but is designed to display the layers of a TImageEnView (i.e. all of the layers of a multi-layer file format, such as a PSD, IEN or SVG file).
To use TImageEnLayerMView, simply set the AttachedImageEnView property to a TImageEnView.

TImageEnLayerMView provides the following features:
- Preview of all layers of a TImageEnView, with thumbnail, layer type, position, size and rotation information
- Selection of thumbnails to select the relevant layer (Optional)
- Buttons to set the Visible, Locked or IsMask status of layers (Optional)
- Dragging of thumbnails to re-arrange them (Optional)
- Dragging of thumbnails outside the control (or clicking Delete) to remove them (Optional)

Note: You can also display layers in a standard TImageEnMView, using AssignLayers

Example

// Set up
IELayerMView1.AttachedImageEnView := ImageEnView1;
 
// Thumbnails or details?
if fShowLayersAsThumbs then
  IELayerMView1.Style := iemsFlat
else
  IELayerMView1.Style := iemsFlatAndWide;

// Background down to front-most, or reversed?
if fLayerViewReversed then
  IELayerMView1.LayerOrder := ieloTopFirst
else
  IELayerMView1.LayerOrder := ieloBackgroundFirst;

// Enable dragging of thumbnails to rearrange layers and remove layers
IELayerMView1.LayerOptions := IELayerMView1.LayerOptions + [ lvDragOrdering, lvDragDelete ];

// Move buttons to the top-right of thumbnail
ImageEnLayerMView1.ButtonParams.Position := iecpTopRight;
