| 摘 要： | 测井曲线幅度较大 ,如应用程序直接向窗口的视区绘制曲线 ,则会使用大量的GDI调用 ,而且测井曲线保存为通用的图像格式难以实现。利用双缓冲技术在内存中绘制整幅测井曲线 ,然后再实现图像显示和保存 ,能较好地解决上面的问题。

| Abstract: | Because the logging curve is usually huge, if a logging curve is drawn directly in the viewport of the application program windows, lots of GDI functions will be applied, which make it different for the logging curve to be saved as an ordinary picture or as a universal image format. However, if double buffering technology is used to draw the entire logging curve in the memory and then displays and saves the image, the logging curve can be easily saved as universal image format. |
