Printing advice

[Lloyd Dupont]

I'm trying to print some of my document.
The problem is, the rendering of the document is not done through GDI+ at all but through plain old GDI, and I need it like that as I am using Uniscribe to layout text.

Anyway, when printing the text is completely out of place, I wonder if it's due to incorrrect Dpi settings? (or something else?)
I will investigate that.....

Anyway if any of you had similar experience and could shed some light?
Here is how I initialize my HDC (Managed C++):
=============== =====
struct HDCInfo
{
HDC hdc;
// to be restored
HGDIOBJ font0;
HGDIOBJ brush0;
HGDIOBJ pen0;
XFORM transform0;
};
void NText::ScriptAn alysis::GetHDC( Graphics^ g, struct HDCInfo& info)
{
array<float>^ matrix = g->Transform->Elements;
pin_ptr<float> p_transform = &matrix[0];

info.hdc = (HDC)(void*)g->GetHdc(true) ;
info.font0 = ::GetCurrentObj ect(info.hdc, OBJ_FONT);
info.brush0 = ::GetCurrentObj ect(info.hdc, OBJ_BRUSH);
info.pen0 = ::GetCurrentObj ect(info.hdc, OBJ_PEN);
::GetWorldTrans form(info.hdc, &info.transform 0);

::SetGraphicsMo de(info.hdc, GM_ADVANCED);
::SetBkMode(inf o.hdc, TRANSPARENT);
::SetWorldTrans form(info.hdc, (XFORM*) p_transform);
}
=============== =====

All my text output looks like shrink.
I mean all the characters are correctly positioned compare to each other, but it just occupies the top left quadrant.

The Preview doesn't display text all :-(
And the printing just shrinking it ?!?.....

I tried to multiply my world transform matrix by thes factor:
static int TextPrintScale( HDC& hdc)
{
HDC screenDc = GetDC(NULL);
int screenDpi = GetDeviceCaps(s creenDc, LOGPIXELSX);
ReleaseDC(NULL, screenDc);
int devDpi = GetDeviceCaps(h dc, LOGPIXELSX);
return devDpi / screenDpi;
}

the weird thing is, it work well if I use this integer division of devDpi / screenDpi.
But first I tryed to used a float factor by returning:
return ((float) devDpi) / screenDpi;

And this was clearly wrong, (the page was clearly scaled too much as if 3 was right but 300.0 / 96.0 was not).
I'm kind of confused about that, I would have expect the float division to be right.
Any thoughts?

Also whatever I do the System.Windows. Forms.PrintPrev iewDialog still display no text at all.... :-/

Lloyd,

You might try cc'ing the folks in
microsoft.publi c.dotnet.framew ork.drawing. They may be able to help you.
