| # i3lock blurred screen inspired by /u/patopop007 and the blog post | |
| # http://plankenau.com/blog/post-10/gaussianlock | |
| # Timings are on an Intel i7-2630QM @ 2.00GHz | |
| # Dependencies: | |
| # imagemagick | |
| # i3lock | |
| # scrot (optional but default) | |
| IMAGE=/tmp/i3lock.png | |
| SCREENSHOT="scrot $IMAGE" # 0.46s | |
| # Alternate screenshot method with imagemagick. NOTE: it is much slower | |
| # SCREENSHOT="import -window root $IMAGE" # 1.35s | |
| # Here are some imagemagick blur types | |
| # Uncomment one to use, if you have multiple, the last one will be used | |
| # All options are here: http://www.imagemagick.org/Usage/blur/#blur_args | |
| #BLURTYPE="0x5" # 7.52s | |
| #BLURTYPE="0x2" # 4.39s | |
| #BLURTYPE="5x2" # 3.80s | |
| BLURTYPE="2x8" # 2.90s | |
| #BLURTYPE="2x3" # 2.92s | |
| # Get the screenshot, add the blur and lock the screen with it | |
| $SCREENSHOT | |
| convert $IMAGE -blur $BLURTYPE $IMAGE | |
| i3lock -i $IMAGE | |
| rm $IMAGE |
this worked for me!
how are the time measurements done?
@z3t0 probably a stopwatch or something...
I like it but it takes a bit of time to blur ...bit insecure
You can use imagemagick's import command to screencap as well, reducing the number of required packages.
A quick suggestion to improve the time to render the blurred image, you could reduce the size of the screen cap before applying the blur:
convert $IMAGE -resize 50%
convert $IMAGE -blur $BLURTYPE $IMAGE
Then put back to 200% to get back to orginal size
convert $IMAGE -resize 200%
Thanks !!!
Inspired from this project, here a little boost i3lock++
I know it's been some time since you published this gist. I used this method until today, but because I use an older computer it would take me 2-5 seconds to take the screenshot, add the effect and then run the i3lock. i3lock-blur flickers and doesnt work in my computer.
I've forked scrot and added a blur option and an option to add an icon here: darddan/scrot
Running scrot -B 5 -i icon.png output.png generates a blurred screenshot with an icon over it in about 300 milliseconds.
