Imagemagick scripts for easy image manipulation.

[viking60]

Imagemagick is..magic but it has a somewhat steep learning curve. It is well worth learning about it and probably you won't bother anyway so we made a script to jump to the good stuff without having to understand it.

You will find the discussion here

You can copy the script above and put it in a file called berserkimg.
Then put berserkimg in /usr/local/bin and chmod it to 777
as root:

Code: Select all

chmod 777 /usr/local/bin/berserkimg

After that you can start the script in a terminal by simply typing

Code: Select all

berserkimg

Using it is simple:
Go to a directory where you have pics that you want to work with.
Then start berserkimg and pick a function like rounded corners by entering 1.

The first thing the script does is to list all your images in that directory just to show you what you have to work with.


Here you find the picture to edit and give a name and extension to the output file.

So if want to manipulate baby.jpg with rounded corners we enter 1 and write:

Code: Select all

baby.jpg rounded_baby.png

make one space between the entries and that is it - the magic will happen and pop up the result on your screen.

Once you close that pic you are back to the menu and can work with other pictures.

You can always go to the directory and see the fruits of your work in rounded_baby.png.

You can call the out file whatever you want and give it other formats than png, of course.

Here is a pic made with the silent movie effect:
