Embodiment Construction

[0014] specific implementation plan

[0015] The computer system used in this example is an ordinary PC system, and the operating system is Windows XP HOME version. However, those skilled in the art will understand that the spirit and scope of the present invention are not limited to any computer model and operating system, as well as specific communication protocols.

[0016] Fig. 1 is a block diagram of the TMAP file structure defined by the present invention. The file structure mainly consists of the following three parts:

[0017] File header (Header):

[0018] The file header defines the global information of the TMAP file type, including but not limited to the following:

[0019] Image file format specification, "TMAP";

[0020] file format version number;

[0021] number of image data files;

[0022] Basic image information: image size, color, compression method, compression ratio, maximum magnification;

[0023] Image layer (Layer) information: maximum number of...

Abstract

The disclosed image browsing method with browser comprises: storing image data by layer / tile with different layer for different image scaling factor, defining image format as TMAP; opening a TMAP file to build required data structure for the browser based on file information; determine current scaling factor selected by user; then selecting the proper layer from file structure; calculating the original-image coordinate for the area selected by user to obtain user-interested area TOI; cleaning current image block sequence, traversing the image block of selected layer to find out the blocks with intersection with ROI, and adding the block information into the sequence when failed; reading data information from the target sequence to decode; sending re-draw view command from the main thread and keeping ready state for other operation. This invention overcomes great data storage difficulty.

Description

technical field [0001] The invention relates to a data browsing\processing system. In particular, the present invention relates to the use of large image data storage and the use of browsers for fast browsing applications of large image data. Background technique [0002] With the development of computer technology, the digital storage of various information has been gradually accepted by people. However, with the increase of various information, the storage, analysis and processing of massive information has become an important topic worthy of research. [0003] Among all kinds of information, text and image information are used most. Generally speaking, images can express more information. However, as people have higher and higher requirements for image quality and precision, the storage, analysis, and browsing of large-capacity images have become a problem. For example, in fields such as medical treatment, semiconductors, and geographic systems, the space occupied by ...
