unix - ImageMagick - how to enforce min/max heights/widths? - Stack Overflow
The short answer is basically just do '200x200' and both dimensions will be reduced to no more than 200 pixels, preserving the aspect ratio.

The '-geometry' option has some weird ways of doing what seems like the same thing, like '^' and '>'; see https://www.imagemagick.org/script/command-line-processing.php#geometry.

Copy GPS coord tags - Wrong Hemisphere!
Add -g1 to last command to see the source of the various GPS tags.


This didn't actually help me; what helped was including *all* the tags that had to do with GPS, except the time/datestamps. I came up with this Bash function to help

<code class="language-bash"># copy EXIF GPS info including altitude from one file to another
exif_gps_from_to() {
exiftool -n -tagsFromFile "$1"\
-GPSVersionID \
-GPSLatitudeRef \
-GPSLongitudeRef \
-GPSAltitudeRef \
-GPSAltitude \
-GPSLongitude \
-GPSLatitude \
-GPSPosition \
"$2"
}
</code>

Deciphering Glyph :: Tips And Tricks for Shipping a PyGame App on the Mac
Luckily the OS ships with the macOS-specific “scriptable image processing system”, which can helpfully convert an icon for you. Make yourself a 512x512 PNG file in your favorite image editor (with an alpha channel!) that you want to use as your icon, then run it something like this:
<code class="language-bash">$ sips -s format icns Icon.png --out Icon.icns</code>
somewhere in your build process, to produce an icon in the appropriate format.

Facebook Knows How to Track You Using the Dust on Your Camera Lens | https://gizmodo.com/
In the course of our year-long investigation into how the social network makes its uncannily accurate friend recommendations to users, Facebook has told us many things it doesn’t do, to ease fears about Facebook’s ability to spy on its users: It doesn’t use proxies for location, such as wi-fi networks or IP addresses. It doesn’t use profile views or face recognition or who you text with on WhatsApp. Most of Facebook’s uncanny guesswork is the result of a healthy percentage of users simply handing over their address books.

In a patent filed two years later, employees on Facebook’s growth team explain why increased user engagement is so important. It leads to “a corresponding increase in, for example, advertising opportunities.”

Hugin tutorial — Stitching flat scanned images
Note, that an alternate approach is to optimize by setting r,v,d,e for all images other than the anchor, which would have only Roll (r) selected in Image orientation and Hfov (v),d,e selected in Lens parameters.


This seems to work, just DEselect these parameters for the "anchor" image.

Paparazzi!
Via: https://discussions.apple.com/message/20348520#20348520
jsd2:

Yes, in fact Paparazzi! was the very first freeware I downloaded and tried. But for the life of me I couldn't figure out how to make it work.

Subsequently, I downloaded at least 12 different freewares that advertised having various wonderful capabilities regarding screenshots and so forth, but not a single one had the capacity to get a screenshot of a long window that extended below the visible screen area.

In most cases, I definitively ascertained that the applications did not have that feature. But in a few cases the software was so confusing and poorly designed that I simply gave up trying to figure out how to make the program work. Paparazzi was one of those cases where I just gave up. I'll return to it now and try to decipher its user interface and try to get it to work again to definitely determine whether it does what I want or not, but I'm not optimistic about my chances.
