首先将坐标映射方式改变为MM＿ANISOTROPIC方式，即各向异性的意思，在这种坐标方式下，X轴和Y轴的逻辑单位可以进行任意的缩入。改变坐标映射方式后，就要确定窗口大小和视口大小，注意窗口大小就是我们在屏幕上所见的尺寸。通过函数得到显示器和打印机每逻辑英寸的像素数量，然后对视口大小进行相应的缩放，就可以便利屏幕上的显示和打印机的输出是一致的了。

Extract and print bounding X and Y cartesian coordinates from georreferenced images.

This a simple program that outputs the result of possibility to construct a triangle with the given 3 positive real numbers x, y, z, as a side lengths of the triangle. -This is a simple program that outputs the result of possibility to construct a

the line-drawing routine so that it always increments x as it plots, it becomes clear that, having plotted a point at (x,y), the routine has a severely limited range of options as to where it may put the next point on the line: It may plot the p
