Imagemagick – Tips and Tricks No. 3

Add a Label to a set of images

First bash script coming up, I’ll explain the best I can: I have a set of images that are all square: w=h. I want to create an image of each image with a label on top,using the filename as the label (without the extension), with a white background, ending up with a 200×250 image with the same name as the original but with “-tab” added. IM will by default squeeze the font size so that the text label always fits. Continue reading

Imagemagick – Tips and Tricks No. 2


The ability to combine a set of images into one image in a variety of ways, essentially replicates the contact sheets of old. Here are a few ways to create a montage. It works best when all the images are the same height and width. IM does not understand page sizes, and will just create a simple image, regardless of the number of images, you can tell IM which images to use though. It also makes sense when testing and creating montages to save the output to a different directory, otherwise your montages will be included in the next iteration! Continue reading

Imagemagick – Tips and Tricks No. 1

Imagemagick (IM) is brilliant! If you want to do something to an image, Imagemagick can do it! Works on Linux and Windows. Can be scripted. Just use Imagemagick for your image manipulation needs.

I have also littered these posts with links to the IM documentation for all the features available with each of the actions. Continue reading

General formatting: colours, borders etc. do help, but even better is to remove all unneeded columns and rows, along with other distractions. For this to work, the top of the last row needs to be visible. Here is a finished example: Continue reading

Digital Slideshow and Clock – Conky / Lua


It is a disgrace really! I have has this running on an ancient laptop for over three years non stop, and not written it up, even failed to write it up on #! Crunchbang forums, where I got all the help from mrpeachy, Sector11, dk75 and others. Time to put that to rights. What is different about this “one”, you ask? Well, we have two conkys running, they are both in the background, so you still have a fully functional PC if you want to use it, you get sexy rounded corners on your image and a nice big digital purple clock.

Xubuntu 16.04 – Repair Nvidia Graphics Install

Don’t know / can’t remember exactly what happened but for some reason my proprietary Nvidia driver stopped working, I lost OpenGL, and with that a lot of functionality on the desktop. After living with it for a couple of months, and there are many different solutions to doing it, I finally got around to sorting it out like this: Continue reading
