When the blocks of masonry with which they built were not in scale with the projected scheme, the real joints were concealed and false ones introduced.
当他们所建造的石方与规划方案不成比例的时候，他们会将真正的接合处隐藏起来，引入假的接合处。

You can prevent this by making sure the scale (how many pixels correspond to each projected unit of distance) is the same (or close) in both the x and y directions.
您可以通过保证范围（每个投影长度单元对应多少像素）在 x 和 y 方向上相同（或接近）来防止这种情况发生。
