| 发明名称 | Method of processing a viewport within large format imagery | ||
| 摘要 | A method of processing a viewport within an image arranged as a matrix of tiles from a container file is provided. The method includes receiving a request to read data of the viewport starting from a point of origin of the viewport, the viewport having a pixel width and a pixel height, the viewport being a portion of an image that is stored in a record within the file container; computing column numbers or row numbers, or both, of the tiles containing the viewport; and reading in parallel or asynchronously each row or each column of tiles containing the viewport. | ||

| 主权项 | 1. A method of processing a viewport within an image arranged as a matrix of tiles from a container file, the method being implemented by a computer system that includes one or more processors configured to execute processing operations, the method comprising: receiving, by the one or more processors, a request to read data of the viewport starting from a point of origin of the viewport, the viewport having a pixel width and a pixel height, the viewport being a portion of an image that is stored in a record within the file container; computing, by the one or more processors, column numbers or row numbers, or both, of the tiles containing the viewport; and reading, by the one or more processors, in parallel or asynchronously each row or each column of tiles containing the viewport. | ||
