The demo \Demos\LayerEditing\Layers_AllTypes shows how to add end edit specific Layers.
Unfortunately, it is not possible to edit the COLOR of the BACKGROUND LAYER (the color of the background behind -not around- the image) - despite I have set ImageEnView.BackgroundStyle = iebsSolid at design-time.
I need a Background Layer that has a solid color and fills the whole ImageEnView area - especially the area behind the image, so when areas of the image are alpha-transparent then that color shines through. Is this possible? |

Hi
ImageEnView.BackgroundStyle does not set the style of the layer 0 (i.e. the "Background" layer), it sets the styling behind layer 0. So the image of layer 0 will generally obscure it, so to see a solid background behind your layers, do one of the following:
1. Set layer 0 to minimum size:
ImageEnView1.Blank();
2. Make layer 0 full transparent:
ImageEnView1.Layers[0].Bitmap.AlphaChannel.AlphaFill( 0 );
ImageEnView1.Update();
3. Make layer 0 the size of the window and fill it:
ImageEnView1.Layers[0].Bitmap.Allocate( ImageEnView1.ClientWidth, ImageEnView1.ClientHeight, clRed );
ImageEnView1.Update();
