[Tex/LaTex] Increasing \footheight with scrlayer-scrpage

header-footerkoma-scriptscrlayer-scrpage

I am experiencing a very strange issue. I am using scrlayer-scrpage to generate headers and footers. For headers, everything works great, but for footers, on every next page the footer height is getting larger (see example). What could be the reason for this?..

\documentclass{scrartcl}

\usepackage[headsepline]{scrlayer-scrpage}
\ifoot[\the\footheight\quad\rule{2px}{\footheight}]{\the\footheight\quad\rule{2px}{\footheight}}

\usepackage{lipsum}
\title{test}

\begin{document}

\lipsum[1-40]

\end{document}

Best Answer

\footheight is total height of the foot, including height (space above the baseline) and depth (space below the baseline) of the foot.

Your rule starts on the baseline. So the height of the foot must be at least the height of your rule plus the depth of a \strutbox. Therefore scrlayer-scrpage enlarges the former \footheight by \dp\strutbox. On the next page your rule starts again on the baseline and so scrlayer-scrpage enlarges the\footheight from the last page by \dp\strutbox again ...

You can shift the rule down by \dp\strutbox:

\documentclass{scrartcl}
\usepackage[headsepline]{scrlayer-scrpage}

\ifoot*{\the\footheight\quad\rule[-\dp\strutbox]{2px}{\footheight}}

\usepackage{lipsum}
\begin{document}
\lipsum[1-40]
\end{document}

Or you have to shorten the rule \dp\strutbox

\documentclass{scrartcl}
\usepackage[headsepline]{scrlayer-scrpage}

\ifoot*{\the\footheight\quad\rule{2px}{\dimexpr\footheight-\dp\strutbox\relax}}

\usepackage{lipsum}
\begin{document}
\lipsum[1-40]
\end{document}

Or you can hide the height of the rule using \smash

\documentclass{scrartcl}
\usepackage[headsepline]{scrlayer-scrpage}

\ifoot*{\the\footheight\quad\smash{\rule{2px}{\footheight}}}

\usepackage{lipsum}
\begin{document}
\lipsum[1-40]
\end{document}

Note that

\ifoot*{\the\footheight\quad\rule[-\dp\strutbox]{2px}{\footheight}}

is a short version of

\ifoot
  [{\the\footheight\quad\rule[-\dp\strutbox]{2px}{\footheight}}]
   {\the\footheight\quad\rule[-\dp\strutbox]{2px}{\footheight}}

[Tex/LaTex] Problems with scrlayer-scrpage

This translates your page layout into KOMA's terms. It may not make the requested changes because I don't know what they are meant to be. Your example does not include any chapters, let alone chapter titles, and it is impossible to guess which distance you are talking about or what is meant to align with what.

Note that, as originally configured, your layout will be inconsistent because both fancyhdr and scrlayer-scrpage will adjust headheight as required, changing the page dimensions in unpredictable ways. To avoid this, you need to make the height at least 33pt and to tell geometry about it.

Note also that scrlayer-scrpage is designed to cooperate with typearea. By using geometry, you lose the advantages of this. Consider whether you could use KOMA's typearea instead.

Here's the initial translation:

\documentclass[12pt,headsepline,footsepline]{scrreprt}
\renewcommand{\familydefault}{\sfdefault}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{geometry}% do you really need this? Better to use KOMA's setup if possible
\geometry{verbose,tmargin=2cm,bmargin=3.5cm,lmargin=3cm,rmargin=2.5cm,headheight=33pt}% the value 33pt is obtained from console warnings output by scrlayer-scrpage - this is the minimum required value, given the inclusion of the graphic - again, it would be better if you could use typearea for this
\usepackage[demo]{graphicx}
\usepackage{xcolor}
\definecolor{mygreen}{RGB}{23,156,125}
\usepackage{scrlayer-scrpage}
\setkomafont{pageheadfoot}{\upshape}
\setkomafont{pagehead}{\slshape}
\setkomafont{headsepline}{\color{mygreen}}
\setkomafont{footsepline}{\color{mygreen}}
\pagestyle{scrheadings}
\automark{chapter}
\ihead{\leftmark}
\ohead{\includegraphics[height=1cm]{IMG/Logo.JPG}}
\ofoot{\thepage}
\cfoot{}
\chead{}

\begin{document}
    Hello
\end{document}

I am guessing that you want the same footer on plain pages as on other pages. This can be achieved using the starred versions of \cfoot and \ofoot, and adding plainfootsepline to the class options:

\documentclass[12pt,headsepline,footsepline,plainfootsepline]{scrreprt}
\renewcommand{\familydefault}{\sfdefault}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{geometry}% do you really need this? Better to use KOMA's setup if possible
\geometry{verbose,tmargin=2cm,bmargin=3.5cm,lmargin=3cm,rmargin=2.5cm,headheight=33pt}% the value 33pt is obtained from console warnings output by scrlayer-scrpage - this is the minimum required value, given the inclusion of the graphic - again, it would be better if you could use typearea for this
\usepackage[demo]{graphicx}
\usepackage{xcolor}
\definecolor{mygreen}{RGB}{23,156,125}
\usepackage{scrlayer-scrpage,kantlipsum}
\setkomafont{pageheadfoot}{\upshape}
\setkomafont{pagehead}{\slshape}
\setkomafont{headsepline}{\color{mygreen}}
\setkomafont{footsepline}{\color{mygreen}}
\pagestyle{scrheadings}
\automark{chapter}
\ihead{\leftmark}
\ohead{\includegraphics[height=1cm]{IMG/Logo.JPG}}
\ofoot*{\thepage}
\cfoot*{}
\chead{}
\begin{document}
    Hello
    \chapter{Some chapter}
    \kant[1-10]
\end{document}

I'm guessing that the further change you want concerns the alignment of the \leftmark in the header. I'm not sure how this constitutes 2 changes, mind, since aligning with the bottom of the image will also reduce the distance....

So, I'm guessing you want something like this:

In which case, it is easiest, I think, to simply define the header in one go, setting the other parts of the header empty:

\documentclass[12pt,headsepline,footsepline,plainfootsepline]{scrreprt}
\renewcommand{\familydefault}{\sfdefault}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{geometry}% do you really need this? Better to use KOMA's setup if possible
\geometry{verbose,tmargin=2cm,bmargin=3.5cm,lmargin=3cm,rmargin=2.5cm,headheight=33pt}% the value 33pt is obtained from console warnings output by scrlayer-scrpage - this is the minimum required value, given the inclusion of the graphic - again, it would be better if you could use typearea for this
\usepackage{graphicx}
\usepackage{xcolor,calc}
\definecolor{mygreen}{RGB}{23,156,125}
\usepackage[markcase=upper]{scrlayer-scrpage}
\usepackage{kantlipsum}
\setkomafont{pageheadfoot}{\upshape}
\setkomafont{pagehead}{\slshape}
\setkomafont{headsepline}{\color{mygreen}}
\setkomafont{footsepline}{\color{mygreen}}
\pagestyle{scrheadings}
\automark{chapter}
\ihead{\leftmark\hfill \includegraphics[height=1cm]{example-image-a}}
\ohead{}
\chead{}
\ofoot*{\thepage}
\cfoot*{}
\chead{}
\begin{document}
    Hello
    \chapter{Some chapter}
    \kant[1-10]
\end{document}

EDIT

In response to the question concerning changing the headers, you can simply redefine \ihead (or \ihead*) as you wish. Do note, however, that doing so is likely to be confusing to readers. The point of running heads is that they contain information which is consistent throughout the document (except on special pages such as the first pages of chapters etc.). Also, the headers should not distract from the body of the document.

\ihead{\includegraphics[height=1cm]{example-image-b}\hfill\includegraphics[height=1cm]{example-image-a}}
\kant[11-14]
\ihead{\leftmark\hfill \includegraphics[height=1cm]{example-image-a}}
\kant[15-20]

EDIT EDIT

You can produce roughly the same page layout using typearea by commenting out the calls to geometry and adding

\areaset[5mm]{155mm}{272mm}

However, if you are stuck with a requirement to use precisely the dimensions given, then you may need to stick to geometry even though it does not cooperate with KOMA. You need to be a bit more careful to make sure you specify adequate headheight etc. in that case.

[Tex/LaTex] scrlayer-scrpage package option list

In chapter 5 »Headers and Footers with scrlayer-scrpage« all the macros and options are explained.

The headsepline can be configured by option headsepline=<thickness>:<lenghth>. You can omit the values. Default thickness is 0.4pt, default length is the symbolic value head.

\KOMAoptions{headsepline} -> head sepline with thickness 0.4pt and width of the head as length

\KOMAoptions{headsepline=1pt} -> head sepline with thickness 1pt and width of the head as length

\KOMAoptions{headsepline=:10cm} -> head sepline with default thickness and length 10cm

\KOMAoptions{headsepline=1pt:10cm} -> head sepline with thickness 1pt and length 10cm

headsepline can be used as package option. But if the values of the key are macros, lengths or counters it is recommended to use \KOMAoption or \KOMAoptions.

To change the alignment of the headsepline with the head you can use one of the options ilines, clines or olines (this is the same as with scrpage2). Default is ilines, ie aligned to the inner margin of head.

To set the color of headsepline change the font element headsepline using \addtokomafont or setkomafont.

So you can replace the outdated scrpage2 code \setheadsepline{.4pt}[\color{black}] by

\KOMAoptions{headsepline=.4pt:head}% .4pt and head are the defaults
\addtokomafont{headsepline}{\color{black}}

Example:

\documentclass[twoside]{scrartcl}
\usepackage{blindtext}% only for dummy text
\usepackage{xcolor}
\usepackage{scrlayer-scrpage}% sets page style scrheadings automatically
\KOMAoptions{headsepline=4pt:5cm,olines}
\addtokomafont{headsepline}{\color{orange}}
\begin{document}
\blinddocument
