The DTWAIN_EnumPixelTypesEx function gets all of the possible pixel types (color settings) that are available for a Source.

 

DTWAIN_ARRAY DTWAIN_EnumPixelTypesEx ( DTWAIN_SOURCE Source );

 

Parameters

An open TWAIN Source.

 

Return Values

If successful, a DTWAIN_ARRAY that will store the pixel types.  NULL is returned on failure.  If the function fails, call DTWAIN_GetLastError() to get extended information.

 

Comments

The DTWAIN_EnumOrientationsEx function has the same functionality as DTWAIN_EnumPixelTypes, except that the DTWAIN_ARRAY is returned to the caller instead of the caller providing a pointer to a DTWAIN_ARRAY as a parameter.
