The present disclosure provides a tessellation data processing method, system, medium and vector graphics processing device. The method includes: constructing a data structure including a content table and information tables in memory; when a vector line generated by tessellation intersects an horizontal/vertical line to obtain a new intersection, reading an address and number of Xnodes or Ynodes of an information table in the content table corresponding to a row/column corresponding to the Y/X coordinate of the intersection; according to the address of the information table and the number of X/Ynodes of the information table, reading corresponding X/Ynodes from the memory; comparing information of the intersection with the X/Ynodes, and updating the X/Ynodes in the information table, or adding an X/Ynode to the information table at a position corresponding to the Y/X coordinates. The tessellation data processing method, system, medium and vector graphics processing device of the present disclosure only require recording fill information of effective intersections generated by tessellation, and do not require recording fill information of all pixels, thereby reducing memory footprint and increasing vector graphic rendering performance.

Tessellation data processing method, system, medium and vector graphics processing device

The present disclosure provides a tessellation data processing method, system, media, and vector graphics processing device. The method includes: according to specified coordinates of intersections, creating different levels of cache tables, wherein the intersections result from vector lines generated by tessellation intersecting lines parallel to an x-axis or y-axis; storing in a content table addresses of information tables in memory, storing in a lowest level cache table an address of the content table in the memory, and storing an address of the lowest level cache table in the memory in a cache table one level higher than the lowest level cache table. The tessellation data processing method, system, media, and vector graphics processing device of the present disclosure store effective data in multi-level lookup tables based on coordinates of intersections, effectively reduce memory footprint, support multi-channel tessellation processing, and enhance the performance of vector graphics rendering.

The present invention relates to an Agomelatine sulfuric acid complex in formula (I) and the preparation method thereof (HX=HSO, RSOH (R&#x2550;CH, Ph, 4-CHPh)). The solubility of the Agomelatine sulfuric acid complex obtained by the method of the present invention is significantly improved compared with Agomelatine, has good stability and higher purity, and is suitable for application in finished-product medicinal preparations. The preparation process is quite simple, and a product with high purity can be obtained without special operations.
