Optimizing JPG and PNG files for the web

Fri, 05 Jul 2024 00:00:00 +0000

I often post images on the web but I rarely think about optimizing the files properly before uploading. Here is a solution for how to do it programmatically in the terminal.

Asking ChatGPT for help

ChatGPT is great for some things, including suggesting program code for well-known problems. However, while it came up with something that worked right from the start, it took a few iterations to come up with a solution that does what I want. I wanted it to work on all image files in all the subfolders (using a recursive search), reduce the images to maxium 1920 pixels, and optimize them without recompression.

Making image parts transparent in Python

Mon, 07 Aug 2023 00:00:00 +0000

As part of my year-long StillStanding project, I post an average image of the spherical video recordings on Mastodon daily.

Average images

The average image is similar to an “open shutter” technique in photography; it overlays all the frames in a video. The result is an image that shows the most prominent parts of the video recording. This is ideal for my StillStanding recordings, because the technique effectively “removes” objects that appear in the recording for a short period of time. That means that people, cars, and animals do not appear. Since I stand still, the average image may look like a photography, but you can see that my face is blurred.

Shell script for compressing PDF files on Ubuntu

Sun, 23 Aug 2020 00:00:00 +0000

I have previously written about a shell script) for compressing PDF files in Ubuntu. Here are some variants of the script.

Low, mid, and high resolution

Low resolution for screen:

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.6 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=out.pdf in.pdf

I prefer the “ebook” mode, which has slightly higher resolution:

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.6 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=out.pdf in.pdf

And then there is the high resolution for printing:

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.6 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=out.pdf in.pdf

Since I don’t need to print things very often, I generally find the “ebook” mode to be a good balance between size and quality.
