Problems solved by technology
[0008] However, in the case where recurring data blocks have a hierarchical structure, when one data block is cached, the time for data conversion may become shorter than when the data blocks referenced by the data block are cached. Long time for data conversion
In other words, data conversion efficiency varies depending on caching in different layers in the hierarchy

Embodiment Construction
[0065] figure 1 It is a figure which shows the structure of the drawing system 100 which concerns on one Embodiment of this invention. The drawing system 100 is a system that uses light to draw a pattern on a photosensitive material on a glass substrate for a liquid crystal display device (hereinafter, simply referred to as “substrate”). Such as figure 1 As shown, the drawing system 100 has a data conversion device 7 and a drawing device 1 . The data converting means 7 converts input data which is vector data representing a pattern into output data which is run length data (ie, performs rasterization processing). The drawing device 1 draws a pattern on the substrate based on the output data generated by the data conversion device 7 . exist figure 1 In , each function of the data conversion device 7 is displayed together. Next, after describing the drawing device 1, the data conversion device 7 and the data processed by the data conversion device 7 will be described.

The invention relates to a data conversion method, a drawing system, and a recording medium. When layered input data are converted into output data in the data conversion method, a first cache efficiency indicating a data conversion efficiency rising degree of a first condition is compared with a second cache efficiency indicating a data conversion efficiency rising degree of a second condition, the first condition is a condition in which a first reference graph element referred in a parent class graph of patterns representative as the input data is cached, and the second condition is a condition in which a second reference graph element referred in the first reference graph element is cached. After the reference graph element with a large efficiency rising degree of data conversion is cached, the input data is converted into the output data by using a reference scanning width of the cached reference graph element. Therefore, the proper reference graph element can be cached according to efficiency rising of the data conversion. Efficiency of the data conversion from the input data to the output data can be properly increased.
Description
technical field [0001] The present invention relates to a technique for converting layered input data representing a plurality of graphic elements into output data as run length data. Background technique [0002] Conventionally, a pattern is drawn by irradiating light onto a photosensitive material formed on a semiconductor substrate, a printed circuit board, or a glass substrate for a plasma display device or a liquid crystal display device (hereinafter referred to as "substrate"). In recent years, a pattern drawing device that directly draws a pattern on a photosensitive material by scanning a light beam has been used as the pattern has become more high-definition. [0003] In the design stage, such a pattern is usually represented by vector data such as CAD (Computer Aided Design) data, and when the pattern is drawn by a pattern drawing device, the following raster image processing (RIP: Raster Image Processing) is performed to convert the vector data Raster data such a...
