Im messing about with images on terminal. This is just for future reference.
Raw
imgManip.md

Using ImageMagick via CLI is esoteric but some google-fu sorted me out.

convert (originalfile) -resize ##% (outputfile) will resize an image by the percentage given. Better than using -scale as it keeps the image quality up. Replace ##% with HxW to make the image resize into dimensions that best fit H or W. eg, a 1024x768 original ran through -resize 80x80 will have width of 80 and height within ratio.

Converting from one imgage type to the next is simple as well. convert png myjpeg.jpg will convert myjpeg.jpg into a png.

Using jp2a as a neat tool to output images via ascii and ansi color codes into the terminal is fun and entertaining, but fleeting.

If I want to save the output for future use and display, I have two options. The first outputs html via jp2a . jp2a --zoom-term --colors --html (originalfile) > newfile.html will put the HTML output from jp2a into an html file. If, instead, I want to save the ansi codes and ascii decorations without formatting into html, I can simply pipe the output of the command jp2a ---colors --zoom-term (originalfile) > newfile.txt and be done.
