PRB: Printer Font too Small with ChooseFont() Common Dialog
This article was previously published under Q89544
In an application for the Microsoft Windows graphical environment, the user
selects a printer font through the ChooseFont() common dialog box function.
When the application calls the CreateFontIndirect() to create the selected
font, even though the style and face name are correct, the point size is
much too small.
The LOGFONT structure returned to the application is based on screen
metrics--even when the user selects a printer font. Because the resolution
(dots per inch) on a printer is generally much greater than that of the
screen, the resulting printer font is smaller than desired.
Modify the lfHeight member of the LOGFONT data structure according to the
printer metrics.
The following code demonstrates how to modify the lfHeight member. The
lpcf variable contains a pointer to the CHOOSEFONT data structure. The
hDC member of the CHOOSEFONT data structure is a handle to the printer
device context.
if (ChooseFont(lpcf))
{
if (lpcf->nFontType & PRINTER_FONT)
{
iLogPixelsy = GetDeviceCaps(lpcf->hDC, LOGPIXELSY);
lpcf->lpLogFont->lfHeight =
MulDiv(-iLogPixelsy, (lpcf->iPointSize / 10), 72);
hPrinterFont =
CreateFontIndirect((LPLOGFONT)(lpcf->lpLogFont));
}
else
{
// Create screen font
}
}
else
{
// Process common dialog box error
}
