TRasterLayer32

Ancestors

TRasterLayer32, as its name implies, has been designed to display raster images. However, rather than assigning images directly to the Image property, the MasterImage property should be assigned instead. This way, whenever the layer is resized or rotated, the layer's Image can be update automatically using a MasterImage transformation. This accommodates any number of layer scalings and rotations without without degrading the displayed image (and without altering MasterImage).

Note: It's important that MasterImage has any transparent pixels around it cropped to prevent the display image offsetting when starting a layer rotation.
