NAME
- CreateBehindLayer
-
Create a new layer behind all existing layers.
SYNOPSIS
result = CreateBehindLayer(li,bm,x0,y0,x1,y1,flags [,bm2])
d0 a0 a1 d0 d1 d2 d3 d4 [ a2 ]
struct Layer *CreateBehindLayer(struct Layer_Info *, struct BitMap *,
d0 a0 a1 d0 d1 d2 d3 d4 [ a2 ]
struct Layer *CreateBehindLayer(struct Layer_Info *, struct BitMap *,
LONG, LONG, LONG, LONG, LONG, ... );
FUNCTION
Create a new Layer of position and size (x0,y0)->(x1,y1) Make this layer of type found in flags. If SuperBitMap, use bm2 as pointer to real SuperBitMap, and copy contents of Superbitmap into display layer. If this layer is a backdrop layer then place it behind all other layers including other backdrop layers. If this is not a backdrop layer then place it behind all nonbackdrop layers.
- Note:
-
when using SUPERBITMAP, you should also set LAYERSMART flag.
