Hi,
I use ImageEn.IEBitmap.RenderToCanvasWithAlpha(ACanvas, p.x, p.y, w, h,0, 0, IEBitmap.Width, IEBitmap.height,intens, rfnone, ielNormal);
procedure. On screen it works perfectly with alpha channel. But on printer all alpha area is printed in black. Any suggestions are welcome.

Regards
juwo

Hi,
try to fill the background in someway, for example drawing a white rectangle:
ACanvas.Brush.Style := bsSolid;
ACanvas.Brush.Color := clWhite;
ACanvas.FillRect(Rect(p.x, p.y, p.x+w, p.y+h));
