【摘要】 受浅层地震野外工作条件的限制,往往不能提供合适的硬件条件实现地震剖面的较大幅面现场连续打印。在简述VC++打印函数和运行顺序的基础上,本文提出浅层地震剖面的多页打印和预览的VC++程序实现方法,指出剖面图像的分页处理要与图形映射模式相关联;由于打印和预览的设备环境不同,实现图形映射时必须采用不同的方法;根据打印程序运行时打印和预览过程存在的差异,指出进行预览的必要性。经打印测试,本文方法是有效的。更多还原

【Abstract】 The continuous field printing of shallow seismic profile with biggist breadth often can not be implemented without the help of suitable hardware.After a brief review of the print functions of Visual C⁺⁺ and their sequences in an application’s running,a programming method for the multipage printing and print preview of shallow seismic profile is presented in this paper.This paper also points out that the dissection of profile image is concerned with the mapping mode,and according to the differences between print and print preview’s device contexts,different measures must be taken to realize the mapping of profile images on these two device contexts,and according to an analysis of the interactive manner of the printing and print preview processes,it is essential to have a print preview before a formal printing.After some printing tests,the method discussed in this paper proves to be available.更多还原
