OPOS Signature Capture Data Format

Hello Everybody,

If this question is in the wrong place - kindly suggest the correct place.

I am developing software that captures signatures from a signature pad and sends it to Microsoft Dynamics for storage and display.

This is a Signature Capture Service Object Driver, and I am using the OPOS standard.

Can someone help me find the exact structure that RMS want's to see this signature data ?

RMS calls GetPropertyString to recieve a BSTR containing the data, this is working correctly, however, the signature displayed is slightly corrupted - appearing to contain a few glitches in what would otherwise be a straight line. It looks very much like there is "noise" in the data.

I know that the data from the physical device is correct, at least in terms of the format they describe. Which is, 2 bytes contain the X coordinate, and then 2 bytes contain the y coordinate ( together, these 4 bytes are 2 wide-chars), and the 2nd of each pair contains the high order byte of the coordinate. Thus, I have to shift the 2nd byte 8 bits left and or it with the

1st byte to obtain the valid coordinate. Thus the data from the device seems to be valid when used this way - but I have no idea whether RMS would be expected to manipulate these bytes this way (and in fact, sending the data in this form to RMS shows nothing). The only way I can get anything to show up in RMS is to put a NULL after every byte in the data as just described - and when I do that - I get this minor corruption.

If anyone has ever seen something like this or knows who I should ask, I would very much appreciate it.

Thank you, Nate Clark
