The IPrintOemUI::QueryColorProfile method allows a user interface plug-in to specify an ICC profile to use for color management.

Syntax

HRESULT QueryColorProfile(
  HANDLE    hPrinter,
  POEMUIOBJ poemuiobj,
  PDEVMODE  pPublicDM,
  PVOID     pOEMDM,
  ULONG     ulQueryMode,
  VOID      *pvProfileData,
  ULONG     *pcbProfileData,
  FLONG     *pflProfileData
);

Parameters

hPrinter

Caller-supplied printer handle.

poemuiobj

Caller-supplied pointer to an OEMUIOBJ structure.

pPublicDM

Caller-supplied pointer to a validated DEVMODEW structure.

pOEMDM

Caller-supplied pointer to the user interface plug-in's private DEVMODEW structure members.

ulQueryMode

One of the following caller-supplied bit flags, indicating the type of profile to be specified.

Flag	Definition
QCP_DEVICEPROFILE	The caller is requesting a device profile.
QCP_SOURCEPROFILE	The caller is requesting a source profile.

pvProfileData

Caller-supplied pointer to a buffer to receive profile information.

pcbProfileData

Caller-supplied pointer to a value representing the size, in bytes, of the buffer pointed to by pvProfileData.

pflProfileData

One of the following method-supplied bit flags, indicating the type of information the method is returning.

Flag	Definition
QCP_PROFILEDISK	The method is returning the file name of an ICC profile in the buffer pointed to by pvProfileData.
QCP_PROFILEMEMORY	The method is returning profile data in the buffer pointed to by pvProfileData.

Return value

The method must return one of the following values.

Return code	Description
S_OK	The operation succeeded.
E_FAIL	The operation failed.
E_NOTIMPL	The method is not implemented.

Remarks

A user interface plug-in's IPrintOemUI::QueryColorProfile method performs the same types of operations as the DrvQueryColorProfile function that is exported by user-mode printer interface DLLs. For information about printer events and how they should be processed, see the description of the DrvQueryColorProfile function.

If you provide a user interface plug-in, the printer driver's DrvQueryColorProfile function calls the IPrintOemUI::QueryColorProfile method. The DrvQueryColorProfile function performs its own processing for the specified event, and then calls the IPrintOemUI::QueryColorProfile method to handle additional processing of the event.

If IPrintOemUI::QueryColorProfile methods are exported by multiple user interface plug-ins, the methods are called in the order that the plug-ins are specified for installation.

For more information about creating and installing user interface plug-ins, see Customizing Microsoft's Printer Drivers.
