Based on the idea
requirements:
- libglm-dev
- libglfw3-dev (only needed if build demo
blur-exp) - libglew-dev
- libgbm-dev
- libegl1-mesa-dev
- libgles2-mesa-dev
- libgdk-pixbuf2.0-dev
mkdir build && cd build && cmake .. && make
after build has done,
use the binary blur_image to blur a image and save as file. show usage by ./blur_image -h
example: ./blur_image -p 10 -r 11 /usr/share/wallpapers/deepin/Garden\ In\ The\ Autumn.jpg -o out.jpg
note: if you run it with a X Server running (which is the most probable case), add sudo at the front.
or you can use render node to do blurring without privilege like
./blur_image -d /dev/dri/renderD128 -p 6 -r 7 /usr/share/wallpapers/deepin/Garden\ In\ The\ Autumn.jpg -o out.jpg
in case if you want to build demo
use cmake -DBUILD_DEMO=on .. instead and after build finished,
use blur-exps to test blurring with windowing system.
