Abstract
Input CAD data and run-length data obtained by performing a RIP process on the input CAD data are acquired. A predetermined conversion process is performed on at least one of the input CAD data and the run-length data to make the data formats of both data comparable and then both data are compared with each other to detect an area having a difference as a defect area in the run-length data. This provides a technique to detect a defect in the run-length data to be used for drawing of a figure before the execution of drawing with a simple structure.
Claims18
A defect inspection apparatus configured for inspecting a defect in run-length data to be used for drawing of a figure, comprising:
- an input data acquisition part configured for acquiring input data describing a figure to be drawn;
- a run-length data acquisition part configured for acquiring said run-length data by performing a raster imaging processing (RIP) process on said input data;
- and
- a defect detection part configured for comparing said input data with said run-length data to detect a difference area as a defect area in said run-length data when it is found;
- wherein said defect detection part comprises
- a data format conversion part configured for performing a predetermined conversion process on at least one of said input data and said run-length data to make the data formats of both data comparable, and
- wherein the defect inspection apparatus further comprises a repair part configured for repairing said defect area to acquire repaired run-length data when the defect area is detected in said run-length data.
A computer-readable recording medium configured for storing a program which is stored in a computer and executed by said computer to cause said computer to function as a defect inspection apparatus for inspecting a defect in run-length data to be used for drawing of a figure,
- wherein said defect inspection apparatus comprises
- an input data acquisition part configured for acquiring input data describing a figure to be drawn;
- a run-length data acquisition part configured for acquiring run-length data by performing a raster image processing (RIP) process on said input data;
- and
- a defect detection part configured for comparing said input data with said run-length data to detect a difference area as a defect area in said run-length data when it is found;
- wherein said defect detection part comprises
- a data format conversion part configured for performing a predetermined conversion process on at least one of said input data and said run-length data to make the data formats of both data comparable, and
- wherein the defect inspection apparatus further comprises a repair part configured for repairing said defect area to acquire repaired run-length data when the defect area is detected in said run-length data.
A figure drawing apparatus configured for drawing a figure onto an output medium on the basis of run-length data, comprising:
- an input data acquisition part configured for acquiring input data describing a figure to be drawn;
- a run-length data acquisition part configured for acquiring said run-length data by performing a raster image processing (RIP) process on said input data;
- a defect detection part configured for comparing said input data with said run-length data to detect a difference area as a defect area in said run-length data when it is found;
- wherein said defect detection part comprises
- a data format conversion part configured for performing a predetermined conversion process on at least one of said input data and said run-length data to make the data formats of both data comparable;
- a repair part configured for repairing said defect area to acquire repaired run-length data when the defect area is detected in said run-length data;
- a drawing run-length data acquisition part configured for acquiring said repaired run-length data as drawing run-length data when said defect area is detected in said run-length data and acquiring said run-length data as drawing run-length data when said defect area is not detected in said run-length data;
- and
- a drawing part configured for drawing a figure onto said output medium on the basis of said drawing run-length data.
A figure drawing system configured for drawing a figure onto an output medium on the basis of run-length data, comprising:
- a defect inspection apparatus configured for inspecting a defect in said run-length data;
- and
- a drawing apparatus configured for acquiring drawing run-length data from said defect inspection apparatus and drawing a figure onto said output medium on the basis of said drawing run-length data,
- wherein said defect inspection apparatus comprises
- an input data acquisition part configured for acquiring input data describing a figure to be drawn;
- a run-length data acquisition part configured for acquiring said run-length data by performing a raster imaging processing (RIP) process on said input data;
- a defect detection part configured for comparing said input data with said run-length data to detect a difference area as a defect area in said run-length data when it is found;
- wherein said defect detection part comprises
- a data format conversion part configured for performing a predetermined conversion process on at least one of said input data and said run-length data to make the data formats of both data comparable
- a repair part configured for repairing said defect area to acquire repaired run-length data when the defect area is detected in said run-length data;
- a drawing run-length data acquisition part configured for acquiring said repaired run-length data as drawing run-length data when said defect area is detected in said run-length data and acquiring said run-length data as drawing run-length data when said defect area is not detected in said run-length data;
- and
- a drawing run-length data transmitting part configured for transmitting said drawing run-length data to said drawing apparatus.
