![]() It used to be possible to crop images automatically by including the command-line option convert -crop 0x0. This command makes it possible to scale, compress and otherwise manipulate images of many different types, including both bitmap (jpeg, gif etc.) and vector formats (pdf etc.). Necessary? Not at all! But I do have fun doing it.Imagemagick is an open-source collection of graphics utilities which includes the convert command. I regularly use functions ranging from a mktest() function, that creates an empty $1.test.js file for me, to more robust createDirectory() functions with a specified language to create entire components, classes, functions, or CSS module scaffolding for me. As with all programming, the possibilities are endless. custom_commands.sh on your system, put it to good use. There we go, using just one line we were able to resize the card images to exactly the height we’d need, while converting them to a more optimized format and severely reducing the size of our assets. Make sure that second argument is in a string, otherwise it will see it as multiple arguments. For me, the most commonly used flag is -resize, but you can find the entire list of parameters available to optionally add at. This allows us to add any additional parameters from ImageMagick that we would like applied to the images. custom_commands.sh we are going to write a function called ctwp() (“Convert to weppy,” I whisper to myself every time I type it). Once we restart (or restart bash), this is going to give us access to any functions we place inside. bashrc, we are going to add this line (I added it below my aliases, but honestly anywhere is fine): We’re going to make a new file in our computer’s home directory. But, we are going to take this an unnecessary step further. Perfect! Now we can do that for every image. webp for us.Īnd the requirements to solve our problem:Īs you may have already derived, we could easily convert and resize the images in one command using ImageMagick:Ĭonvert bull.jpg -resize 圆00 bull-optimized.webp
