Intermec Fingerprint v7.61 Programmers Reference Manual Ed. 7282
Chapter 3 Image Transfer
Example 1: Bitmap encoding
To clarify this, lets try a simple example. Xs represent black dots in the nal
printout. The pattern shown is 22 bits wide and 28 rows high.
NOTE!
The bit order in each byte. Note also word ll to nearest word (16 bit).
To the right is a hex representation of the pattern, as it would appear
in a memory dump.
To get the pattern to appear as printed on this page with direction one, the
last row (row 27) should have the lowest address.
