Patent ID: 7538767

Claim:
A computer program product comprising: a tangible computer storage medium having computer readable code, the computer readable code being effective to: identify a down point location; determine one or more start point fractional values based upon the down point location; select one of the start point fractional values for a view screen segment, wherein the selecting further comprises computer readable code effective to: identify a view screen segment identifier that corresponds to the view screen segment; determine a last bit value of the view screen segment identifier; select a fifty percent start point fractional value in response to determining that the last bit value is one; in response to determining that the last bit value is zero, determine a second to last bit value of the view screen segment identifier; select a twenty five percent start point fractional value in response to determining that the second to last bit value is one; in response to determining that the second to last bit value is zero, determine a third to last bit value of the view screen segment identifier; and select a twelve and one-half percent start point fractional value in response to determining that the third to last bit value is one; compute a view screen segment start point using the selected start point fractional value; generate image values corresponding to the view screen segment starting at the view screen segment start point; and display the image values on a view screen.
