pngcopy

Now if only I could do this:

pngpaste - | convert - -resize 50% - | pngcopy

Interesting idea; what is your actual use case for copying a PNG, resizing it and copying it back into the clipboard? Where does it end up?

I am grabbing screen captures on a retina display. Sometimes but not always, I want the resolution halved, and I do this a lot so I don’t want to screen cap to a file, and have to worry about cleaning up trash. One simple solution is to make a simple terminal command which allows me to down sample the clipboard.

like this:

[Cmd-shift-4-space] to copy a window to the pasteboard run terminal command [Cmd-v] pastes the down sampled image in keynote (usually).

This does make me wonder if there's something buried in the OS X API that allows for saving different resolutions. Otherwise, pngcopy would be a whole new thing and expand the scope of pngpaste considerably.

Incidentally, I've been doing the following in iTerm2:

pngpaste - | convert - -interpolate nearest -filter point -sample 50% - | imgcat

And then I just copy the image out of the terminal. But it would be nice to replace that last command with pngcopy. ;-)

pngpaste - | convert - -interpolate nearest -filter point -sample 50% - | imgcat

Ahh, nice.

Looks like someone has raised a PR for it! https://github.com/jcsalterego/pngpaste/pull/15

Assuming it works, it'd be great to have this, for me at least it makes sense to have pngcopy and pngpaste to match pbcopy and pbpaste.

Thanks - I need to revisit things here and merge all the good code and ideas people have contributed.

Just leaving my useless +1 in here 😅

I would love to see #15 merged and eventually make its way to brew

Sorry all, #15 has been closed and I've recommended the author make pngutils and fork pngpaste.
