DTWAIN_SOURCE	Source,
LPDTWAIN_FLOAT	lpResolution );

Parameters

Return Values

The return value is TRUE if successful. Otherwise FALSE is returned.

Comments

The DTWAIN_GetResolution function gets the current resolution value for the Source Source and on return, fills the DTWAIN_FLOAT that lpResolution points to . Please note that lpResolution is an address of a DTWAIN_FLOAT (an LPDTWAIN_FLOAT).

Note that some Sources do not support retrieving the resolution, so the return value for DTWAIN_GetResolution will always be FALSE.

To set the current resolution value, call DTWAIN_SetResolution.

For languages that have difficulties with DTWAIN_FLOAT parameters, the alternate function that can be used as a replacement for DTWAIN_GetResolution is DTWAIN_GetResolutionString.
