Problems solved by technology

[0003] In the report technology, the display of graphic objects is often involved in the report preview. The generation of these graphic objects requires multiple steps to complete. For each step, the CPU needs to do a lot of calculation processing, which takes a long time.
In order to improve the speed of displaying graphics, when displaying graphic objects, the method of generating graphic objects as original bitmap information and displaying them on the corresponding components of the system is often used, so th

Abstract

The present invention provides a report form graph display memory optimization method and a device. The method comprises the steps as follows: step S102, a tool class for carrying out mutual conversion to bitmap and condensed information as well as a display component for displaying graphs is generated; step S104, graphic information is generated according to a report form graph; the graphic information is condensed into a graphic information handle through the tool class, and the graphic information handle is transmitted to the display component; step S106, the display component transmits the graphic information handle to the tool class; the tool class converts the graphic information into a bitmap graphic object and transmits the bitmap graphic object to the display component; step S108, the display component receives and displays the bitmap graphic object in graphs. Therefore, the present invention can decrease the memory occupying amount brought by a plurality of window display graphs, improve the quantity of graph display windows opened at the same time, and preferably solve that conflict of report form graphs on speed and space.

Description

technical field [0001] The invention relates to a display technology for generating graphics when previewing a report, and more specifically, to a memory optimization method and device for generating graphics for browsing reports in multiple windows. Background technique [0002] With the rise and development of computer science, we have entered a new era, a large amount of information and data, oncoming. It is more urgent than ever to use scientific methods to organize data, so as to accurately analyze and accurately judge all aspects of information from different perspectives. Therefore, the application of report technology, the supporting technology in database technology based on the needs of information system business development, is even more urgent. [0003] In the report technology, the display of graphic objects is often involved in the report preview. The generation of these graphic objects requires multiple steps to complete. For each step, the CPU needs to do a...
