Subject: reduce image resolution of a bitmap or jpg again

Hi Michel

I've asked you that one before and you did reply saying: "With Envision you use the TResizeTransform to change the dimensions, and the resolution is specified in the XDotsPerInch and YDotsPerInch properties. See more details in the online help".

I tried a few things to reduce the image resolution by using the XDotsPerInch and YDotsPerInch properties but i still haven't managed to reduce the resolution. I looked at the online help too. I realise that I can read the resolution of the image in question and I have managed to write to these properties (I changed them to be 18 from their initial value of 96). The properties values have changed but the image hasn't even after .update, .redraw(true) or .invalidate.

Can you please see if Envision actually allows me to change the resolution of an image and tell me how to do it ? I would really appreciate it.

Thanks a lot.
David

Here's the two lines I wrote in an attempt to change the resolution:
isb1.Graphic.XDotsPerInch:= 18;
isb1.Graphic.YDotsPerInch:= 18;
