# pixelfloot
|
|
|
|
Origin: https://git.la10cy.net/DeltaLima/pixelfloot
|
|
|
|
an very simple and dirty pixelflut client to draw images, written in bash.
|
|
pixelfloot was built during the 37c3. in its actual state, its just a mess. I hope i will find time to put it in a more usable and readable format.
|
|
|
|
## examples
|
|
|
|
- Display image: `./pixelfloot.sh floot images/lucky-cat.jpg`
|
|
- set position: `X=1337 Y=420 ./pixelfloot.sh floot images/lucky-cat.jpg`
|
|
- image random position: `./pixelfloot.sh floot images/lucky-cat.jpg chaos`
|
|
- wider "chaos-radio": `X_MAX=1000 Y_MAX=600 ./pixelfloot.sh floot images/lucky-cat.jpg chaos`
|
|
- image shake position: `./pixelfloot.sh floot images/lucky-cat.jpg shake`
|
|
- set the position : `X=420 Y=420 ./pixelfloot.sh floot images/lucky-cat.jpg shake`
|
|
- image bounce across screen: `./pixelfloot.sh floot images/lucky-cat.jpg bounce`
|
|
- can set the "bounce-radius": `X_MAX=1000 Y_MAX=500 ./pixelfloot.sh floot images/lucky-cat.jpg bounce`
|
|
- move image with your cursor (needs `xdotool`): `./pixelfloot.sh floot images/lucky-cat.jpg cursor`
|
|
- Use a color as "alpha" (remove background): `ALPHACOLOR=FF00FF ./pixelfloot.sh floot images/cursor.ppm cursor`
|
|
- write text: `TEXT="pixelflut makes a lot of fun! :)" ./pixelfloot.sh floot text`
|
|
- set the size of the Textbox and the textcolor: `COLOR=FF00FF SIZE=240 TEXT="colors, yeah!" ./pixelfloot.sh floot text`
|
|
- you can also use ALPHACOLOR here, or set your: `ALPHACOLOR=000000 TEXT="colors, yeah!" ./pixelfloot.sh floot text`
|
|
- define your own background color: `BGCOLOR=0000FF SIZE=240 TEXT="colors, yeah!" ./pixelfloot.sh floot text`
|
|
- increase No of concurrent connections: `FLOOTFORKS=8 ./pixelfloot.sh floot images/lucky-cat.jpg`
|
|
- specify IP and PORT: `IPFLOOT=127.0.0.1 FLOOTPORT=1337 ./pixelfloot.sh floot images/lucky-cat.jpg`
|
|
- for drawing big areas, like 1280x720, use LARGE mode: `LARGE=true ./pixelfloot.sh floot images/xphg.jpg`
|
|
- default field size are 64k lines. You can adjust it with LOLFIELDSIZE:
|
|
`LOLFIELDSIZE=16000 LARGE=true ./pixelfloot.sh floot images/xphg.jpg`
|
|
- drawing an gif file with proper animation: `LARGE=true ./pixelfloot.sh floot images/dancing_banana.gif`
|
|
- Adjust the speed with FRAMETICKTIME in seconds: `FRAMETICKTIME=0.03 LARGE=true ./pixelfloot.sh floot images/shaking_cat.gif`
|
|
|
|
```shell
|
|
$ ./pixelfloot.sh help
|
|
./pixelfloot.sh [floot|convertimg] [FILENAME|fill|text] ([MODE])
|
|
|
|
floot: flooting the target specified with IPFLOOT
|
|
convertimg: converts an image to a command list file in /tmp
|
|
to use it, start 'USECACHE=true ./pixelfloot.sh floot [FILENAME]', where FILENAME
|
|
is the original image file.
|
|
|
|
FILENAME: path to any picture imagemagick can handle (env X, Y, RESIZE,
|
|
BORDERCOLOR, ALPHACOLOR)
|
|
fill: create a filled area with (env COLOR, W (width), H (height), X, Y)
|
|
text: create a textbox (env TEXT, FONTSIZE, SIZE, COLOR, BGCOLOR, BORDERCOLOR
|
|
ALPHACOLOR)
|
|
|
|
MODE: static (env X and Y for position)
|
|
chaos (env X_MAX and Y_MAX for position range)
|
|
shake (env X and Y for position)
|
|
cursor
|
|
bounce (env Y_MAX and X_MAX for max bounce range, BOUNCESTEP for step size)
|
|
|
|
available env vars to configure:
|
|
IPFLOOT(string), FLOOTPORT(int), USECACHE(bool), FLOOTFORKS(int)
|
|
SIZE(int), TEXT(string), FONTSIZE(int), BGCOLOR(hex), COLOR(hex)
|
|
BORDERCOLOR(hex), X(int), Y(int), X_MAX(int), Y_MAX(int), H(int), W(int)
|
|
RESIZE(int), ALPHACOLOR(hex), BOUNCESTEP(int), LARGE(bool)
|
|
ANIMATION(bool), FRAMETICKTIME(float)
|
|
```

Running on my Ryzen 4700G with [wellenbrecher](https://github.com/bits0rcerer/wellenbrecher) 1280x720 and three workers,
|
|
i get around 1,5Gbit/s localhost traffic.
