Creates an IXpsOMGlyphs interface, which specifies text that appears on a page.

Syntax

HRESULT CreateGlyphs(
  [in]          IXpsOMFontResource *fontResource,
  [out, retval] IXpsOMGlyphs       **glyphs
);

Parameters

[in] fontResource

A pointer to the IXpsOMFontResource interface of the font resource to be used.

[out, retval] glyphs

The new IXpsOMGlyphs interface pointer.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For information about XPS document API return values that are not listed in this table, see XPS Document Errors.

Return code	Description
S_OK	The method succeeded.
E_POINTER	fontResource or glyphs is NULL.
XPS_E_NO_CUSTOM_OBJECTS	fontResource does not point to a recognized interface implementation. Custom implementation of XPS Document API interfaces is not supported.

Remarks

The code example that follows illustrates how this method is used to create a new interface.


IXpsOMGlyphs       *newInterface;
// this interface is defined outside of this example
//  IXpsOMFontResource *font; 

// Note the implicit requirement that CoInitializeEx 
//  has previously been called from this thread.

hr = CoCreateInstance(
    __uuidof(XpsOMObjectFactory),
    NULL,
    CLSCTX_INPROC_SERVER,
    _uuidof(IXpsOMObjectFactory),
    reinterpret_cast<LPVOID*>(&xpsFactory)
    );

if (SUCCEEDED(hr))
{
    hr = xpsFactory->CreateGlyphs (font, &newInterface);
    if (SUCCEEDED(hr))
    {
        // use newInterface

        newInterface->Release();
    }
    xpsFactory->Release();
}
else
{
    // evaluate HRESULT error returned in hr
}
