Depending on your eyes and your screen, you may want to adjust the font size that
Interrogator uses to display with to make it larger or smaller. If your eyesight
is good,you might want a smaller size to see more text on your screen. If you're
getting a bit older, or your screen has very dense resolution, you should adjust
the font size larger. All the icons and everything else will scale upward or downward
along with the font size.

Note that different systems handle fonts differently. Usually, MacOS X systems are
more smooth than X11 systems, but there are exceptions, and a lot depends on the
specific font family you choose. There's so many situations that it's hard to predict
what problems you will have. Here are some pathologies you may run into:
- Some font families don't draw larger than a certain maximum. This may show up when
you ask for a larger size, but the size doesn't change. Other times, the text will
draw small glyphs in a large glyph box - you will see lots of white space between
the characters in a line, and between the lines.
- Some font families don't draw smaller than a certain minimum. This may show up
when you ask for a smaller size, but the size doesn't change. Other times, the text
might draw in other ways, they might lose so much resolution that they be read, or
might even disappear.
- Some font families only come in specific sizes, and attempts to draw sizes in between
have problems. This is common for bitmapped fonts. For instance, a font might be
fine in sizes 14 and 18, but might have no size 16. Attempting to draw in size 16
may yield either size 14 or size 18, or perhaps size 14, 18 or 8 stretched to size
16. Stretching typically creates a rough, jagged appearance.
In all of these cases, try a different font family, or attempt to find sizes that
work correctly and stick to them.
Sometimes the font size numbers are interpreted as points, which are usually
about 1/72 inch in absolute distance. Other times, they are interpreted as pixels.
The original Macintosh screen was assumed to be 72 pixels per inch, even when it
wasn't, which was convenient. Because it was used for desktop publishing, therefore
printing on paper, the effective paper size was most important. Most screens these
days have a higher resolution, and printing on paper is less important. Most systems
these days cannot tell the absolute size of a video or flatpanel monitor, only the
number of pixels wide and high. One way or another, a font that claims to be 12 points
could easily show up on the screen as being 16 or 24 pixels high. Your best bet is
to simply experiment with your system until you like what you see.
You might also notice on Unix/Linux systems that the font family names vary from
one program to another. For instance, one program might list "Helvetica"
but another might list "Adobe Helvetica". You may have to try both in the
preference file until you get something that works. If the font name you specify
isn't found or is somehow 'misspelled' according to the rules, you will instead get
a default font.
The sparse and dense commands change the packing density of files in a directory window. It's easiest to see starting with the most sparse setting.
Interrogator draws the files in descending columns, starting from the upper left corner. Ideally, all the files would be the same size and their names would all be the same length. Unfortunately, many have long names - often the limit on filename length is 255 characters.
Interrogator deals with this by allowing long names to extend to the right. Subsequent columns simply have a gap to avoid these long names. When this happens a lot, the resulting display can appear scattered. Gaps are so large that it appears more like isolated strips of files in a jumble.
To avoid this, Interrogator allows you to adjust the column width. A wider column width will appear more tidy, but will use up more screen area. A tighter column width will pack files in more densely, but will look more chaotic due to all of the gaps.
An interesting phenomenon also happens at dense column widths when the average file ends up needing two or three column widths. It can appear that the column width changes chaotically, but in fact, various files are being laid out with two or three column widths being used. This can be confusing.
Note also that the density setting varies from one directory to another,
as the filename lengths vary.
