LyX:浮点的垂直位置

LyX:浮点的垂直位置

使用包裹浮动时,我总是会遇到一个问题,那就是它们会从其所属段落的开头开始一行。现在我发现了一个技巧,如何将它们提升到这里但是使用它会对文档中其他位置的全宽浮动产生意想不到的后果。

诀窍是将此行添加到序言中:

 \setlength{\intextsep}{0cm plus1cm minus1cm}

它对包裹的浮动很有效,但上面和下面的文本一些其他浮动现在将进入图形 - 似乎没有规则现在浮动上方和下方有多少空间。有些看起来像以前一样,而其他的则将有文本进入其中,无论我在浮动上方和下方添加多大的垂直空间。

我讨厌手动调整每个浮动元素周围的空间,我害怕回到浮动元素对齐不佳的时代。这是怎么回事?我应该怎么做才能让浮动元素对齐正确是否有足够的、一致的空间供常规浮点使用?

编辑:这是同一个 LyX 文件的结果,左侧没有那一行,右侧有那一行。我还擅自将右侧版本的换行行数减少了一行。显然,右侧换行浮动的垂直位置看起来更好,但右侧浮动的垂直位置变得更糟。

答案1

该长度\intextsep由位于文本页面内的浮点数(根据参数)使用,[h]而不是浮动到页面的顶部或底部或添加到浮动页面。

0cm plus1cm minus1cm

长度的自然宽度(首选宽度)为 0cm,但如果页面内容需要拉伸,则可以拉伸到 1cm,如果页面过满且空白需要缩小,则可以缩小到 -1cm。

因此,此设置表明,如果将浮动元素设置在页面中间,则它可能会被上下 1cm 的负空间所包围,从而会按该量叠印文本,或者可能会被浮动元素上下最多 1cm 的空白所包围。

基本上,没有文档需要此设置。它不一定会产生糟糕的排版。它可能会意外地延伸到合理的空间,例如 10pt 左右,但那只是运气好而已。

为了进行比较,标准课程(10pt 选项)使用以下设置

\setlength\intextsep   {12pt plus 2pt minus 2pt}

因此空间在 10pt 和 14pt 之间,自然大小为 12pt。

wrapfig将这个空间添加到包装的图形中,因此如果你想全局设置它,那么使用就足够了

\setlength\intextsep   {0pt}

不允许 1cm 的过度打印,但最好保留h浮点数,只需修补 wrapfig 即可删除\intextspace顶部

答案2

经过多次尝试和错误,最有效的方法是在浮动内的图片顶部添加 -4mm 的负垂直空间。只有当浮动与新页面的第一行一起放置时,才必须省略此负垂直空间。

现在,来自问题的 LyX 示例文本源(没有“特殊”行)如下所示(请注意部分\begin_inset VSpace -4mm \end_inset- 这会产生很大的不同!):
