- The _\bq_\bi_\bx program bounces a series of line segments around
- its window. This is truly the swiss army chainsaw of qix
- programs. If you know of one with more display modes, I
- want to know about it.
-
-O\bOP\bPT\bTI\bIO\bON\bNS\bS
- _\bq_\bi_\bx accepts the following options:
-
- -\b-w\bwi\bin\bnd\bdo\bow\bw Draw on a newly-created window. This is the
- default.
-
- -\b-r\bro\boo\bot\bt Draw on the root window.
-
- -\b-m\bmo\bon\bno\bo If on a color display, pretend we're on a
- monochrome display.
-
- -\b-i\bin\bns\bst\bta\bal\bll\bl
- Install a private colormap for the window.
-
- -\b-v\bvi\bis\bsu\bua\bal\bl _\bv_\bi_\bs_\bu_\ba_\bl
- Specify which visual to use. Legal values are the
- name of a visual class, or the id number (decimal
- or hex) of a specific visual.
-
- -\b-s\bse\beg\bgm\bme\ben\bnt\bts\bs _\bi_\bn_\bt_\be_\bg_\be_\br
- How many line segments should be drawn. Default
- 50.
-
- -\b-s\bsp\bpr\bre\bea\bad\bd _\bi_\bn_\bt_\be_\bg_\be_\br
- How far apart the endpoints of one segment should
- be from the next. Default 8.
-
- -\b-s\bsi\biz\bze\be _\bi_\bn_\bt_\be_\bg_\be_\br
- The maximum distance one endpoint of a segment is
- allowed to be from the opposite end of that seg-
- ment. Default 0, meaning unlimited.
-
- -\b-c\bco\bou\bun\bnt\bt _\bi_\bn_\bt_\be_\bg_\be_\br
- How many qixes to draw. Default 1.

-
- -\b-c\bco\bol\blo\bor\br-\b-s\bsh\bhi\bif\bft\bt _\bd_\be_\bg_\br_\be_\be_\bs
- If on a color display, the color of the line seg-
- ments will cycle through the spectrum. This spec-
- ifies how far the hue of each segment should be
- from the next, in degrees on the HSV wheel.
- Default 3.
-
- -\b-d\bde\bel\bla\bay\by _\bm_\bi_\bc_\br_\bo_\bs_\be_\bc_\bo_\bn_\bd_\bs
- How much of a delay should be introduced between
- steps of the animation. Default 25000, or about
- 0.025 seconds.
-
- -\b-r\bra\ban\bnd\bdo\bom\bm The _\bq_\bi_\bx will wander around the screen semi-ran-
- domly. This is the default.
-
- -\b-l\bli\bin\bne\bea\bar\br The opposite of _\b-_\br_\ba_\bn_\bd_\bo_\bm: the _\bq_\bi_\bx will travel in
- straight lines until it reaches a wall, and then
- it will bounce.
-
- -\b-s\bso\bol\bli\bid\bd If this is specified, then the area between the
- line segments will be filled in with the appropri-
- ate color, instead of the _\bq_\bi_\bx simply being com-
- posed of one-pixel-wide line segments. This
- option looks really good in color.
-
- -\b-h\bho\bol\bll\blo\bow\bw The opposite of _\b-_\bs_\bo_\bl_\bi_\bd; this is the default.
-
- -\b-x\bxo\bor\br If this is specified, then qix segments will be
- drawn and erased with xor, instead of being drawn
- in some color and erased in the background color.
- This implies _\b-_\bm_\bo_\bn_\bo, in that only two colors can be
- used.
-
- -\b-t\btr\bra\ban\bns\bsp\bpa\bar\bre\ben\bnt\bt
- If this is specified, and _\b-_\bc_\bo_\bu_\bn_\bt is greater than
- 1, then each qix will be drawn in one color, and
- when they overlap, the colors will be mixed. This
- only works on P\bPs\bse\beu\bud\bdo\boC\bCo\bol\blo\bor\br displays. This looks
- best in conjuction with _\b-_\bs_\bo_\bl_\bi_\bd.
-
- -\b-n\bno\bon\bn-\b-t\btr\bra\ban\bns\bsp\bpa\bar\bre\ben\bnt\bt
- Turns off _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt.
-
- -\b-a\bad\bdd\bdi\bit\bti\biv\bve\be
- If _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt is specified, then this option
- means that the colors will be mixed using an addi-
- tive color model, as if the qixes were projected
- light. This is the default.
-
- -\b-s\bsu\bub\bbt\btr\bra\bac\bct\bti\biv\bve\be
- If _\b-_\bt_\br_\ba_\bn_\bs_\bp_\ba_\br_\be_\bn_\bt is specified, then this option
- means that the colors will be mixed using a sub-
- tractive color model, as if the qixes were
- translucent filters.

-
- -\b-p\bpo\bol\bly\by _\bi_\bn_\bt
- How many vertices each qix-line should have: the
- default is 2, meaning the traditional qix line
- shape. Three will yield triangles, and so on.
-
- -\b-g\bgr\bra\bav\bvi\bit\bty\by
-
- -\b-n\bno\bo-\b-g\bgr\bra\bav\bvi\bit\bty\by
- Whether there should be downward attraction. For
- example, the options -\b-g\bgr\bra\bav\bvi\bit\bty\by -\b-l\bli\bin\bne\bea\bar\br will make
- everything move in nice smooth parabolas. Gravity
- is off by default.
