Imagemagick rotate11/3/2023 Here’s how you can use mogrify to rotate images: mogrify -rotate -90 /path/to/images/*.jpg The difference between convert and mogrify is that mogrify overwrites the original image file, while convert creates a new file. Mogrify is another command from the ImageMagick suite that can be used to rotate images. ![]() The rotated-"$file" part of the command specifies the output file name, which will be the original file name prefixed with “rotated-“. The 90 after -rotate is the rotation angle in degrees (90 degrees in this case). In this command, /path/to/images/*.jpg should be replaced with the path to your images. Here’s the command you can use: for file in /path/to/images/*.jpg do convert "$file" -rotate 90 rotated-"$file" done The -rotate option followed by the rotation angle in degrees will do the trick. If you don’t have ImageMagick installed, you can do so by running the following command: sudo apt-get install imagemagick Rotating Images with ImageMagickĪfter installing ImageMagick, you can use the convert command to rotate your images. It can read, convert and write images in a variety of formats. ImageMagick is a powerful open-source software suite that allows you to create, edit, and compose bitmap images. Create a shell_command in HA to ssh into the addon container and run my script, e.g.Ĭommand_1: 'echo "SOME COMMAND" | ssh 'įull disclosure: I’m still working this out myself and currently use the process I described in an earlier post.Before we begin, make sure you have the necessary permissions to install software and modify the images you plan to rotate. ![]() Setup SSH keys between the core and addon containers.Create and test my script inside the addon.This way they are automatically added each time that container is recreated. Configure the SSH & Web Terminal addon by including any needed APKs to its configuration.This is objectively better long-term as the end-user is no longer required to edit the core container. This is another rabbit hole you may consider pursuing as it keeps the HA core container in an unmodified immutable state. The reason behind the removal make sense security-wise, but it’s still a bummer.Īnyways, in the release notes of that change made a comment about using ssh in its place. Unfortunately, this was removed in a release late last year. I used to use the stdin feature of the SSH & Web Terminal addon. TBH I’ve been trying to figure out a very similar setup of running 3rd party shell commands within HA. But still, shell_command - which I use in my automation - has no access to the convert or magick command. ![]() Same thing with my attempt to use the plugin “SSH & Web Terminal” which offers the ability to make Alpine packages available on startup. Well it was available in the bash shell after install - but not from shell_command. But which container? homeassistant? Tried that - didn’t work. What would be the best way to approach this? I searched the forums and found advice to ssh into the docker container and apk-install ist. I already got the automation working using shell_command to curl the snap.jpg from the camera - but for the cropping and rotating part I’d need ImageMagick which isn’t available in the default setup. I want to be able to process a still image taken from my front door camera and process (rotate & crop) it before sending it via Pushover when somebody rings my doorbell. ![]() I’m running the supervised version on a Pi4. Hi, this is my first post and I’m fairly new to Home Assistant.
