我有等高线地形图，但是我想删除其中白色背景并且把等高线变白，代替以前的黑色。

I have topography line work but I want to remove the white background and I also want the line work to be white, not black.

给出了平面等高线地形图，带地物符号的工程地形图，立体等高线图及逼真地形图等多种造型方法。

And various methods of modelling, that is, contour maps, engineering maps with surface feature symbols, 3 D contours and realistic maps are given.

等高线就像是这幅图的地形图。

And then, the contour plot will be the topographical map for this graph.

这是一幅由美国地形勘测出来的地形图，基本上，所有海拔等高线在一块陆地上。

So, a topographic map, this one from the US geological survey shows you, basically, all the level curves of an altitude function on a piece of land.
