xdotool 可以与亚像素分辨率一起使用吗？

Question

我有一块图形输入板 (ug-1200b)，用于 Ubuntu。我编写了一个（有点丑陋的）脚本，它使用 libusb 来获取原始输入，使用 xdotool 来模拟鼠标移动和点击。这个脚本运行得很好，但我想知道是否有办法访问平板电脑的更高分辨率。

平板电脑的触控笔分辨率约为 144336x8192，屏幕分辨率为 1024x782，因此每个像素的触控笔位置有 >10 步。我想将这些报告为鼠标移动。

我的问题是 xdotool 有一个基于像素的鼠标移动系统。我正在使用，xdo_move_mouse(xdo, X, Y, 0);但它仅限于整数值，所以我必须四舍五入，并删除额外的分辨率。

有没有什么办法可以解决这个问题？
