baseline

问题 I have this plot: and want to flatten its baseline/reduce offset using Matlab. Basically like a baseline correction for a spectrum but here I've got a mesh and can't get my head around it how to flatten its baseline when dealing with a matrix? Basically the dot should stay but the surrounding is actually zero. The noise can stay, though. Here is the image: I am wondering if something like this works: for x=1:1201 for y=1:1201 Ibasetest = polyfit(x,y,1); end end Simply put do a baseline for

问题 I thought I understand how these enums work based on this post. When I tried it using the following code, it does not seem to work. Row( mainAxisAlignment: MainAxisAlignment.center, crossAxisAlignment: CrossAxisAlignment.baseline, textBaseline: TextBaseline.ideographic, children: <Widget>[ Text( 'abcdefg', style: TextStyle( fontSize: 50.0, fontWeight: FontWeight.w900), ), Text( 'hi', style: TextStyle(fontSize: 15.0), ), ], ), However, whatever I choose to use as text baseline (ideographic or

问题 The TextBaseline enum in Flutter has two options: alphabetic ideographic How do these values actually change the baseline? I'm adding my answer below. 回答1: TextBaseline.alphabetic The alphabetic baseline is the line that the letters in alphabets like English sit on. Here is an example: You can see that the English letters sit nicely on the line, but it cuts through the Chinese characters. TextBaseline.ideographic When you use the ideographic option, though, the baseline is at the bottom of

问题 I am trying to align the baseline of some text in a div to the very bottom edge of said div (such that characters like g and j would actually overflow the div) I can only seem to align the bottom edge of the text element to the bottom edge of the div . I have tried to use vertical-align with values baseline and bottom on the inner and outer element, but without success. div { height: 80px; width: 300px; background: #ff5; position: relative; } span { font-size: 30px; position: absolute; left:
