Hi

I wonder if this is possible:

I have a map background image of 500x500
On that I overlay a rainfall radar image of 500x500.
Great every things fine.
What would be better was a higher resolution map say 1000X1000 (to give me greater map resolution) but obviously when I do that the other layers don't match. It would be great if I could magnify the other layers independently of the base layer so that they did match.

I have tried setting a magnify record :

rec.Enabled:=True;
rec.Rate:=2;
rec.Style:=iemRectangle;
rec.Source:=iemBackgroundLayer;

but that seems to affect all the layers and not just a single layer. Is what I'm trying to do achievable?

Bruce.

Hi,
you can resize the second layer, with:
ImageEnView.Layers[1].Width := 1000;
ImageEnView.Layers[1].Height := 1000;

or

ImageEnView.LayersCurrent := 1;
ImageEnView.Proc.Resample(1000, 1000);
