Here's a throwaway exercise I just did, a tiger I sketched from a
photograph.

The main problem is, I can't figure out how to add stripes; if I try
to use | and \ for stripes, the outline of the body, especially the
legs, gets obscured. And it's a little small to use thick-line or
texture techniques. Well, maybe not. Thick stripes might be okay,
though not quite realistic.
The other problem is, I did this on my terminal at home, which I've
decided has the wrong proportions. In particular, I think that these

should look almost square, but on this terminal they look taller than
wide. Even worse, the ones in the center of the screen look a little
bit thinner than the ones on the edges. This terminal's idea of a
square is more like this:
______
| |
| |
|______|
And the font here also has a few oddities, so I don't do much serious
ascii drawing at home any more; just random scribbling and some
touchup work.

I'm using an X terminal (SGI Iris). The pics I've created were on a 2:1 font, which appears to be -misc-fixed-medium-r-normal--13-120-75-75-c-70-*-1 using a dark-on-light color scheme. I prefer this because it makes images easier to print. > (1) Is there a pos/neg greyscale that works for all terminals? > (2) Which characters look the same on all terminals? > (3) Which control characters like ^L work for all terminals? I'm not sure I can come up with useful data on these, but I'll try. ---------------------------------------------------------------------- > (1) Is there a pos/neg greyscale that works for all terminals? The short answer is, "probably not." In the Utah Raster Toolkit, under the rletoascii documentation, they suggest the string @BR*#$PX0woIcv:+!~"., for the X 6x13 font. Only 22 characters ... strange. It's wrong for my font, though; my grays look better with @BQ8HO#$*kfwoxr:+=-,. Use a chart like the one shown below to determine good values for your font. A good text editor with search-and-replace functionality should make it easy to try out different values, or email me for the source code that generates charts like this. Other fonts I've tried out from the emacs font menu include: 8x8 -schumacher-clean-medium-r-normal--*-80-*-*-c-*-*-1 #$BH8O@k*focr+=^-~:,. 6x12 -misc-fixed-medium-r-semicondensed--12-110-75-75-c-60-*-1 $@B#8H*Owkfcr+=:,^~-.

Precious few of them, it seems. And yet general shape is pretty consistent. It depends if you're looking for darkness weights or connecting lines within the character box. Weights vary greatly, especially for symbols. Compare my results above for the #, $, and @ characters. They move all over. Even letters can vary widely; fonts with serifs will be darker than those without. Shapes are more consistent; -, /, and \ will pretty much look the same everywhere. Shapes to be wary of are: ~ sometimes sits high, sometimes in middle ^ same reason * same reason & sometimes closed, sometimes open | same reason ' sometimes hooked left, sometimes straight [] sometimes centered, sometimes far off <> sometimes touch top and bottom, sometimes centered 0 sometimes with slash, sometimes open l sometimes with base, sometimes not y sometimes straight tail, sometimes curved ---------------------------------------------------------------------- > (3) Which control characters like ^L work for all terminals? ^L, ASCII code 12, is the only consistent one I'm aware of. Then again, I'm pretty ignorant about other termcaps. - Dr. Guz -- * Sean Gugler // __ |) | # # # | # # | # # # | # * 758 Clara Vista Ave // ~T \ /_ __ l_l_l_l_l_l_l_l_l_l_l_l_l * Santa Clara, CA 95050 // [ / )^ (' ) / / ,' I Got My Life * (408) 249-1683 // ~~' / . j' `'` ~~ For A Song
