推荐答案

发布评论中嵌入的（我的）解决方案...用户已更改映射模式 [ ^ ]因此逻辑坐标不再与设备单元匹配。



更改映射到MM_TEXT使两个测量结果一致。



一些参考资料：



GDI制图 [ ^ ]

设备无关的像素 [ ^ ]

协调空间和转换 [ ^ ]

Posting (my) solution embedded in the comments ... User had changed the mapping mode[^] so the Logical co-ordinates no longer matched the device units.

Changing the mapping to MM_TEXT brought the two measurements into line.

Some reference material:

Device Independent Pixels[^]

它在像素中。看起来你的Windows比屏幕大。检查设置大小的位置。

it is in pixel. Looks like your Windows is bigger than the screen. Check where you set the size.
