Xterm gap in openbox tiling

Question

I'm setting up the manual tiling for openbox + arch setup. Below is key-bindings in my rc.xml:
<keybind key="W-a">
<!-- Begin the keychains to manage windows -->
<!-- aeiah's semi-tiling mode -->
<!-- changes by brontosaurusrex, inspired by
http://urukrama.wordpress.com/2011/10/30/manual-tiling-in-openbox/ -->
<!-- super + a & normal numerals -->
<!-- small top left -->
<keybind key="1">
<action name="UnmaximizeFull"/>
<action name="MoveResizeTo">
<x>0</x>
<y>0</y>
<width>50%</width>
<height>50%</height>
</action>
</keybind>
<!-- small top right -->
<keybind key="2">
<action name="UnmaximizeFull"/>
<action name="MoveResizeTo">
<x>50%</x>
<y>0</y>
<width>50%</width>
<height>50%</height>
</action>
</keybind>
<!-- small bottom left -->
<keybind key="3">
<action name="UnmaximizeFull"/>
<action name="MoveResizeTo">
<x>0</x>
<y>50%</y>
<width>50%</width>
<height>50%</height>
</action>
</keybind>
It worked fine with chromium, skype, sublime-text, lxterminal and other windows as well but I see gaps when I try to resize xterm. I've read online and people says xterm resize depends on symbols, not sure what does this mean but is there any workaround for this problem? Main reason I like to use xterm is because in other terminal emulator my color theme for EMACS get messed up.

Answer 1

Xterm size is determined by rows and columns of text.  It won't let you have a partial column or a partial row.  The number of pixels used for a row or column will depend on the particular font itself and the size you select for the font in your X resources configuration.
You are able to nudge the effective row height with xterm's 'scaleHeight' resource.  It adjusts the space between lines.  I use scaleHeight to avoid bumping DejaVu Sans Mono's low-hanging underscore from the line below.
