Doing the math, that's 644 pixels wide and 726 pixels high. Thus, I wrote a small script to rotate a JPEG image by 90, keeping the EXIF header. exiftool keeps it, but it's not very handy to use. This creates an image that's composed of the six screenshots, with a 1-pixel border around each. The problem with jpegtran is that it does rotate the image, but it discards all the EXIF header data.
Choose the storage: Insert the SD card into the computer. Choose the Home Assistant OS that matches your hardware (RPi 3 or RPi 4). Select Other specific-purpose OS > Home assistants and home automation > Home Assistant. To create a montage of six of these images, in a grid that's two screenshots wide by three tall, I can use this command: $ montage acronia.png \ Choose the operating system: Select Choose OS. In my case, my screenshots are already the same size: 320x240 pixels. The -loop option sets the number of times the GIF will loop.
Now, choose File > Open Image and pick an image on your Raspberry Pi. The general syntax of the montage command looks like this: montage First of all, you can try it out by opening up your terminal ( Ctrl+Alt+t) and typing the following: convert -delay 10 -loop 0 image.jpg animation.gif The -delay option sets the amount of time (in 100ths of a second) between frames. For slightly more power in your image editing, open Mirage (Menu > Graphics > Mirage).

ImageMagick is a full suite of tools, and the one I use here is the montage command. The Raspberry Pi Touch Display is an LCD display which connects to the Raspberry Pi through the DSI connector. To do that, I use the ImageMagick montage command. Let's say I wanted to share a montage or "image grid" of several screenshots. While you could use a desktop graphics program like GIMP or GLIMPSE to adjust or combine photos and graphics, sometimes it's just easier to use one of the almost dozen tools from ImageMagick.įor example, I frequently find myself creating image montages to share on social media. A Raspberry Pi Compute Module 3 Lite (or non-Lite with eMMC for advanced users) Two cameras for the Raspberry Pi with short cables (V1 cameras in our case) A. ImageMagick is the "Swiss Army knife" of manipulating images on the command line.
