NAME
- CreateUpfrontLayer
-
Create a new layer on top of existing layers.
SYNOPSIS
result = CreateUpfrontLayer(li,bm,x0,y0,x1,y1,flags [,bm2])
d0 a0 a1 d0 d1 d2 d3 d4 [ a2 ]
struct Layer *CreateUpfrontLayer(struct Layer_Info*,struct BitMap *,
d0 a0 a1 d0 d1 d2 d3 d4 [ a2 ]
struct Layer *CreateUpfrontLayer(struct Layer_Info*,struct BitMap *,
LONG, LONG, LONG, LONG, LONG, ... );
FUNCTION
Create a new Layer of position and size (x0,y0)->(x1,y1) and place it on top of all other layers. 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.
- Note:
-
when using SUPERBITMAP, you should also set LAYERSMART flag.
