WIAS_HRESULT The WIAS_HRESULT macro writes a diagnostic message to the Wiatrace.log file.
WIAS_LERROR The WIAS_LERROR macro is obsolete. It is recommended that the WIAS_ERROR macro be used instead.The WIAS_LERROR macro writes a diagnostic WIA_ERROR message to the log file.
WIAS_LHRESULT The WIAS_LHRESULT macro is obsolete. It is recommended that the WIAS_HRESULT macro be used instead. The WIAS_LHRESULT macro translates an HRESULT value into a string and writes the string to the diagnostic log file.

wiasDebugError The wiasDebugError function is obsolete.
wiasDebugTrace The wiasDebugTrace function is obsolete.
wiasDownSampleBuffer The wiasDownSampleBuffer function takes in a buffer of DWORD-aligned pixel data and downsamples it (produces image data of lower resolution) to the specified size and resolution.
wiasFormatArgs The wiasFormatArgs function formats an argument list into a packaged string for logging.
wiasFreePropContext The wiasFreePropContext function releases the memory occupied by a WIA_PROPERTY_CONTEXT structure.
wiasGetChangedValueFloat The wiasGetChangedValueFloat function determines whether a property with a floating-point value has been changed by an application.
wiasGetChangedValueGuid The wiasGetChangedValueGuid function determines whether a property with a GUID value has been changed by an application.
wiasGetChangedValueLong The wiasGetChangedValueLong function determines whether a property with a long integer value has been changed by an application.
wiasGetChangedValueStr The wiasGetChangedValueStr function determines whether a property with a string value has been changed by an application.
wiasGetChildrenContexts The wiasGetChildrenContexts function retrieves an array of item contexts belonging to the current item's children.
wiasGetContextFromName The wiasGetContextFromName function retrieves the item context for an item name.
wiasGetDrvItem The wiasGetDrvItem function retrieves a driver item.
wiasGetImageInformation The wiasGetImageInformation function retrieves transfer context information from an item.
wiasGetItemType The wiasGetItemType function indicates the item type.
wiasGetPropertyAttributes The wiasGetPropertyAttributes function retrieves the access flags and valid values for a set of properties.
wiasGetRootItem The wiasGetRootItem function retrieves the root item context of a specified WIA item.
wiasIsPropChanged The wiasIsPropChanged function tests whether a specified property has been changed by an application.
wiasParseEndorserString The wiasParseEndorserString function parses an endorser string, replacing WIA service-defined and vendor-defined tokens in the string with values associated with those tokens.
wiasPrintDebugHResult The wiasPrintDebugHResult function is obsolete.
wiasQueueEvent The wiasQueueEvent function informs the service that the device generated an event.
wiasReadMultiple The wiasReadMultiple function retrieves multiple property values from a WIA item.
wiasReadPropBin The wiasReadPropBin function retrieves a binary-data property value from a WIA item.
wiasReadPropFloat The wiasReadPropFloat function retrieves a floating-point property value from a WIA item.
wiasReadPropGuid The wiasReadPropGuid function retrieves a GUID property value from a WIA item.
wiasReadPropLong The wiasReadPropLong function retrieves a long integer property value from a WIA item.
wiasReadPropStr The wiasReadPropStr function retrieves a string property value from a WIA item.
wiasSendEndOfPage The wiasSendEndOfPage function calls the client callback routine during a data transfer, sending the current total page count.
wiasSetItemPropAttribs The wiasSetItemPropAttribs function sets the access flags and valid values for an item's set of properties.
wiasSetItemPropNames The wiasSetItemPropNames function writes property names to item properties.
wiasSetPropChanged The wiasSetPropChanged function modifies a property context to indicate that a property is being changed.
wiasSetPropertyAttributes The wiasSetPropertyAttributes function sets the access flags and valid values for a set of properties.
wiasSetValidFlag The wiasSetValidFlag function sets the valid values for a WIA_PROP_FLAG property.
