Silverlight - UseLayoutRounding

目中有个复杂的自定义控件，运行程序时，控件上的多个TextBox的边框比正常的TextBox边框要模糊，显得很难看。调试多次后发现，包含TextBox的Grid使用了如下属性值 UseLayoutRounding="false" 将该值设为true (该属性的默认值也为true)，问题解决。查阅一下该属性的文档，原来该属性设为true就是解决subpiexl展示时可能会引起的界面模糊等问题:
The intention of layout rounding is to prevent subpixel rendering logic from producing antialiasing effects that generally are regarded as a poor visual presentation. One of the most extreme examples of this would be if you had a single-pixel straight black line on exactly a half-pixel boundary of the pixel grid. Subpixel rendering would average the pixels on either side of the .5 division. Instead of a single-pixel line of 100% black, it would render a 2-pixel wide line of 50% gray.

使用整数来定位界面元素的位置，亦可避免类似的界面显示问题:
