print stretched graph image

[Ohad]

I'm looking for a way to print a cwgraph stretched on a complete page ( larger then screen size)
Is there one?

Under the directory where you installed Measurement Studio, look at the example project under VC\Examples\Ui\Common\Printing. The dialog class has a OnPrintWysiwyg method and a OnPrintBestFit method. I think that the OnPrintBestFit method will demonstrate what you're looking for.

I have component works starter kit , So this example is not available, can please you provide a copy?

Hi Again,

I found the example on a demo disk. For some reason the printout only uses half of the page (a4)either on landscape or portrait. What am I missing?

To update the example code so that it behaves differently from only using half of the page like you're seeing, look at this section of the code in OnPrintBestFit:

if (bResizeGraph) {
// create a rectangle to resize the graph to (on the screen)
CRect rcNew;
rcNew.left = 0;
rcNew.top = 0;
rcNew.right = (long)(cInchesWide * logicalPixelsPerInchX_Screen);
rcNew.bottom = (long)(cInchesTall * logicalPixelsPerInchY_Screen);

// resize the graph so it will render larger (with more detail)
// the FALSE tells it to not redraw
m_Graph.MoveWindow(rcNew, FALSE);
}

// Calculate a rectangle (in printer coordinates) to print the
// graph in.
rc.left = 0;
rc.top = 0
;
rc.right = (long)(cInchesWide * logicalPixelsPerInchX_Printer);
rc.bottom = (long)(cInchesTall * logicalPixelsPerInchY_Printer);

Adjust the calculation for the rcNew.bottom and rc.bottom according to what you want.
