Declaration

TIEImageLayer = class(TIELayer);

Description

TImageEnView supports multiple layers, allowing the creation of a single image from multiple source images (which can be resized, rotated, moved, etc).
TIEImageLayer is a descendent of TIELayer which contains an image.


You can create image layers with code using LayersAdd or by user action by setting MouseInteractLayers to mlCreateImageLayers.

Review the Layer Documentation for a full description of layer support.

Demos

Examples

// Load an image layer and apply a pink border
ImageEnView1.LayersAdd( ielkImage );                 // Append an image layer
ImageEnView1.IO.LoadFromFile('C:\New Zealand.jpg');  // Load image into the new/active layer
ImageEnView1.CurrentLayer.BorderColor := $008000FF;
ImageEnView1.CurrentLayer.BorderWidth := 3;
ImageEnView1.Update();


// Fix the aspect ratio of an image (that has been resized)
if ImageEnView1.CurrentLayer is TIEImageLayer then
  ImageEnView1.CurrentLayer.RestoreAspectRatio();
ImageEnView1.Update();

// Allow users to create and edit image layers
ImageEnView1.LayerOptions := ImageEnView1.LayerOptions + [ loAutoPromptForImage ]; // Prompt user to browse for image
ImageEnView1.MouseInteractLayers := [ mlCreateImageLayers, mlMoveLayers, mlResizeLayers ];
