I have a hard time remembering all those ImageMagick parameters, so I was glad that Stephan posted this: [Wayback/A] Processing a Number of Image Files – Seaside Testing
Via: [Wayback/Archive] Stephan Kämper on Twitter: “Another note to self: How I can resize image files using @ImageMagick. ➙ …”

The [Wayback/Archive] Online GIF rotator does not justify the tool enough as it:
I used it at C13/C14 wiring diagram live/neutral/earth, which originally [Wayback/Archive] had the image from IEC 60320 – Wikipedia: C13/C14_coupler: File:IEC60320 C13.jpg – Wikipedia in original upright position:
The online image editor with this image is at [Wayback/Archive] Online GIF rotator with C13 female cable end that has holes.
The rotated image is now at [Wayback/Archive] ezgif-7-8f95ded85c.jpg (340×600) – hopefully the last link now fails (:

For my link archive: [WayBack] imagemagick – Command line convert webp to jpg? – Unix & Linux Stack Exchange
All these archives contain both the
cwebpanddwebpprecompiled executables, along with thelibwebp.alibrary and C headers (the latter allowing you to add WebP encoding or decoding to your own programs).

I used the tips at [Archive.is] Digitally Free: Censor An Image In GIMP to ensure some sensitive information was redacted from a picture I published on the internet.
dfree got much further than I needed, so I stayed at a Gaussian Blur with an 80 pixel radius which was more than enough to blur out a few rectangular areas but still show the user-experience of the underlying controls.

Blurring is like a hash function: it cannot be undone, but with enough plain text to blur examples, you can reconstruct the plain text: [WayBack] Why blurring sensitive information is a bad idea | dheera.net | Dheera Venkatraman’s web site
As an alternative, randomly add noise or move pixels. I used [WayBack] Censoring image in GIMP – Graphic Design Stack Exchange. For the example on the right, I used “Filters → Noise → Spread” from the Stack Exchange answer.
With enough randomness, it is much harder to construct plain/hash combinations.

Interesting tool:
I wrote a program to clean up scans of handwritten notes while simultaneously reducing file size.

Often, SVG animates a lot better than GIF. Keep this in mind:
Not only should the image be a good candidate for SVG, but SVG should also be a good candidate for the image.
such as:
- Logos,
- non-complex,
- vector-based illustrations,
- user interface controls,
- infographics,
- and icons.

A long time ago, I wrote about Steps for adjusting a whiteboard photo in Paint.NET.
GIMP does an even better job with these steps:
Once: install the clean-whiteboard-photo script
The above steps will add this menu option to GIMP: menu “Filters” -> “Whiteboard” -> “Clean whiteboard photo”
For every picture: make it less ugly

Based on a few links, these are the steps I used to enhance the photo of a whiteboard using Paint.NET:
These are the links I used to come to this list:
