Systems and methods for improving performance of trigonometric and distance function calculations during printing and display
Consistent with disclosed embodiments, systems and methods for optimizing printing of a print job comprising graphics by a printer are presented. In some embodiments, the method calculating optimal granularity for the print job, based on specified resolution and page size; generating at least one trigonometric table with the calculated granularity; determining if a job command in the print job comprises a trigonometric function; and, if so, obtaining at least one trigonometric value from the at least one trigonometric table based on information in the job command. A similar process may be used to optimize printing by reducing the number of distance calculations performed by using sub tables.
1. A non-transitory, computer-readable memory that stores instructions which, when executed by a processor, perform a method for optimizing printing of a print job comprising graphics by a printer, the method comprising:
calculating optimal granularity for the print job, based on specified resolution and page size for the print job;
generating at least one trigonometric table with the calculated granularity;
determining if a job command in the print job comprises a trigonometric function; and
if so, obtaining at least one trigonometric value from the at least one trigonometric table based on information in the job command.
2. The computer-readable memory of claim 1 , wherein the step of obtaining at least one trigonometric value from the at least one trigonometric table further comprises:
if the job command requires use of an original angle that is not in the range 0 to 90 degrees, determining a mirror angle to the original angle;
obtaining at least one trigonometric value from the at least one trigonometric table based on the mirror angle.
3. The computer-readable memory of claim 1 , wherein the step of generating at least one trigonometric table with the calculated granularity further comprises:
determining a set of most likely page size and resolution combinations; and
generating at least one trigonometric table with the calculated granularity only for the most likely page size and resolution combinations.
4. The computer-readable memory of claim 3 , wherein the step of determining a set of most likely page size and resolution combinations is determined based on the print job.
5. The computer-readable memory of claim 3 , wherein the step of determining a set of most likely page size and resolution combinations is determined based on a characteristic of the printer.
