IPrintOemUni3::GetImplementedMethod method (prcomoem.h)

  • Article

The IPrintOemUni3::GetImplementedMethod method is used by Unidrv to determine which IPrintOemUni interface methods a rendering plug-in has implemented.

Syntax

HRESULT GetImplementedMethod(
  PSTR pMethodName
);

Parameters

pMethodName

Caller-supplied pointer to a string that represents the name of an IPrintOemUni interface method, such as "ImageProcessing" for IPrintOemUni3::ImageProcessing or "FilterGraphics" for IPrintOemUni3::FilterGraphics.

Return value

GetImplementedMethod must return one of the following values.

Return code Description
S_OK
 The operation succeeded (that is, the specified method is implemented).
S_FALSE
 The operation failed (that is, the specified method is not implemented).

Remarks

A rendering plug-in for Unidrv must implement the IPrintOemUni3::GetImplementedMethod method, together with several other methods in this interface. For those methods that are optional, IPrintOemUni3::GetImplementedMethod examines the input method name string and returns a value that indicates whether the associated method is implemented within the plug-in. For example, if IPrintOemUni3::GetImplementedMethod is called with the string "ImageProcessing", it should return S_OK if the IPrintOemUni3::ImageProcessing method is implemented and S_FALSE otherwise.

The IPrintOemUni3::GetImplementedMethod method must recognize the following name strings:

"CommandCallback"

"Compression"

"DownloadCharGlyph"

"DownloadFontHeader"

"DownloadPattern"

"FilterGraphics"

"GetPDEVAdjustment"

"HalftonePattern"

"ImageProcessing"

"MemoryUsage"

"OutputCharStr"

"SendFontCmd"

"SetBandSize"

"TextOutAsBitmap"

"TTDownloadMethod"

"TTYGetInfo"

"WritePrinter"
