然后，它使用一个映射填充该区域，这个映射是用于对每个笔触的绘图区域着色的图像缓冲区。
It then fills the area with a mapping, which is an image buffer used to color up the painting area of each stroke.
窗口服务器为客户提供了一块共用内存区域用来绘图，然后(用gpu)将其混合为帧缓冲。
The window server provides a region of Shared memory to clients for drawing and then composites this into the frame buffer (on the GPU).
该模式为图表绘图提供了更多的屏幕区域。
“我们已经对整个区域进行了高密度的全覆盖式绘图，”Plaut说，“但我们并没有把该区域孤立出来。”
"We have mapped the whole area with a high density of coverage," Plaut said. "These are not isolated features."
每一个应用程序都有为它们自己预留的一块显示区域，就好象QuickDraw一样，不同的是，Quartz是接受从客户端发送的命令来绘图。
Applications each had a region of the display reserved on their behalf, as with QuickDraw, but drew into it with commands sent from the client.

During drawing, the image in the pattern color is tiled as necessary to cover the given area.
基本原理是根据研究地区内控制井的资料，求得该区域网格化后各节点处的参数值，经过数字-字符转换处理，由打印机实现绘图。
Given the data of control Wells in a given area, the drawing will be done on the printer by calculation of the parameters at the netted nodes and digit-character conversion.
绘图结构中包含了一个RECT数据结构，它包含了完全封闭更新区域的最小矩形以及一个标志，指明背景是否需要擦除。
The paint structure contains a rect data structure that has the smallest rectangle that completely encloses the update region and a flag that specifies whether the background has been erased.
