I need to create a program using Lazarus/FPC to access a data

Hi, I would like to know how can I let a CGI app return a JPeg image
from a TChart.
Here's what I'm doing:

TRequest;
AResponse: TResponse; var Handled: Boolean);

Yes, but, how can I use a TCanvas in a CGI app?
If I write:
Chart.PaintOnCanvas(TCanvas(lCanvas), Rect(0, 0, 100, 100));
I get an Access Violation.

TAChart should be prefectly capable of rendering on bitmap-based canvas.

Hi Bo,
I found these 2 links with google. They discuss the unit libusb which seems to
