TCustomDesignerLayer32

Hierarchy

TCustomDesignerLayer32 is the ancestor class for all designer layers, layers that won't form part of a final, non-design merged image (see TLayeredImage32.GetMergedImage).

There are 2 types of designer layers:

TButtonDesignerLayer32. Typically these button objects are controlled by MouseMove events via calls to TLayeredImage32.GetLayerAt, and they're used to transform images (reposition, rotate, resize, projective transform etc) and in constructing lines and polygons. The easiest way to create designer button layers is to use the CreateSizingBtnsGroup and CreateButtonGroup functions in Image32_Layers.
TDesignerLayer32. Unlike TButtonDesignerLayer32 objects are 'non-clickable' as they won't be returned by calls to TLayeredImage32.GetLayerAt. These layers may contain hidden images, background hatched images, grid-line images, rulers, just about any kind of visual designer aid. TDesignerLayer32 also provide a number of designer drawing methods that may be useful for drawing hit-test regions, group bounds, virtual spline control points etc.

The Examples folder contains sample applications demonstrating the use of designer layers.
