Parameter
Command
pData
pString
Explanation
Specifies the reading area to set in pString.
Example:
When you use the area of X = 0, Y = 500, CX = 1000,
CY = 1500,
specify pString = "0, 500, 1000, 1500".
X is the X coordinate of the start of the specified area.
Y is the Y coordinate of the start of the specified area.
CX is the X coordinate of the end of the specified area.
CY is the Y coordinate of the end of the specified area.
The values specified here affect MapMode.
Use the null character string ("") to cancel the specified area.
If the range of specified area exceeds the available range of the device,
it is reduced to within the effective range.
When you specify the reading area, you must set the size of check in the
DocumentWidth and DocumentHeight properties before executing the
EndInsertion method.
Be sure to specify the X coordinate of the end of the specified area.
Scanning fails if the length from the specified coordinates to the left end
of the paper is less than 50 mm. In this case, ECHK_PTRERROR is
notified as ErrorEvent.
Use the CHK_DI_ENDINSERTION_EXTEND command to enable the
setting. Please refer to CHK_DI_ENDINSERTION_EXTEND for details.
The settings with this command are effective only for check scanner
mode. Although during card scanner mode, a reading area can be set
by executing this command, the settings are not reflected to card
reading directly. If these settings are set during card scanner mode,
the settings become effective after changing the mode to check scanner
mode, and only for reading checks.
