no. 1 example

[0067] The first example: the current user clicks on the Dir0 tree node, the system judges whether each picture pointer in the Dir0 tree node is in the saved mapping table, and realizes it through traversal. If there is a pointer to the picture to be parsed in the mapping table, it means parsing For example, 11 of the 15 pictures have been parsed, and the pictures can be directly read from the saved memory address according to the picture memory pointer corresponding to the picture, while 4 have not been parsed, and need to be read from the bottom layer according to the picture pointer The picture buffer data is stored in the memory, the picture is parsed, and the picture is successfully parsed, and the picture is displayed in the thumbnail preview area, and the corresponding relationship between the picture pointer and the picture memory pointer of these pictures is saved in the mapping table for the next use.

[0068] Second instance: the current user clicks on the Dir0 tree node, and the system judges whether at least one of the picture pointers in the Dir0 tree node appears in the mapping table, and immediately performs a quantity judgment when one of them is found out of date, for example, as mentioned above, the current file directory has 15 pictures, and the number of pictures in the current file directory that has been parsed saved in the mapping table is less than 15, it proves that all the pictures in the current file directory have been Read the picture from the memory address. If there are 15 pictures in the current file directory, but the number of parsed pictures in the current file directory saved in the mapping table is only 11, it proves that there are 4 pictures in the current file directory that have not been parsed, so find To get unresolved image pointers, you need to read the image buffer data from the bottom layer to the memory according to the image pointers, an...

Abstract

The invention relates to a system and a method for quickly previewing pictures. The system comprises a preview starting module, an information storage module, a judgment module, a picture resolving module and a picture display module, wherein the preview starting module receives the current file catalog preview instruction, and sends a picture pointer list in the current file catalog; the information storage module stores resolved picture pointers of all file catalogs in a memory and a mapping list of picture memory pointers; the judgment module judges whether the picture pointers in the current file catalog are matched with any picture pointers in the mapping list according to the picture pointer list and the mapping list, sends the picture memory pointers corresponding to the matched picture pointers to the picture display module for display, and sends the non-matched picture pointers to the picture resolving module for resolving; and the acquired picture memory pointers are displayed and stored. According to the system, the resolved picture data is directly called when pictures are previewed, and the non-resolved pictures are resolved, so that the processing speed of previewing the pictures is increased.

Description

technical field [0001] The present invention relates to a picture preview technology, more specifically, to a fast picture preview system and method. Background technique [0002] Qt is a cross-platform C++ graphical user interface application framework. Based on this application framework, various rich graphical controls can be developed, and various rich tools can be developed in combination with C++ to realize various functions. Qt provides application developers with all the functionality needed to create state-of-the-art graphical user interfaces. [0003] Qmap in Qt is currently the fastest GIS engine system that supports vector map calling and display in the Internet environment. The ultra-high-speed graphic data analysis technology can support high-speed map browsing and application on PC and mobile terminals under various bandwidths. Compared with traditional geographic information systems, Qmap has achieved a leap in user experience and development methods. [00...
