Hello,

I have several TChart objects that I wish to print 6 per page. I use
the Canvas->CopyRect() of my printer object and copy the contents of
each chart to the correct location using the Chart->DelphiCanvas
property. Unfortunately, I have come across a problem of a printer
dialog window printing over part of my chart.
Is there a way to get the Chart's actual bitmap or Canvas even if there
is a window over it at the time of the request? Or maybe is there a
better way to print this?

Thanks,
fakepoo

I have created a temporary solution but I would still like to know of a
better way.

My solution:

I created a list of (Graphics::TBitmap) objects and copy the contents
of the delphicanvas into them before calling Printer()->BeginDoc().
Unfortunately, these bitmaps have a maximum size so I divided their
widths and heights by ten in order to bypass the EOutofSources error
that I was getting. After copying all of the bitmaps, I call
Printer->BeginDoc() then copy all of these bitmaps to Printer->Canvas.

Note: this method does effect the resolution which is why I would still
like to pursue alternative solutions.

Hi fakepoo
Using the Chart1.PrintPartialCanvas methods allows sending multiple charts to a printer canvas without using a bitmap.

This link can be helpful, contains example code from Mr. Peter Below that uses PrintPartialCanvas:

Thank you so much for the reply. It now works fine and is much simpler.
