That must be an amazing feeling! Is this a feature that's still in macOS today? Can I see it in action?

- herodotus 7y agoThe feature is there. I assume our code is still used, but it may have been rewritten since I retired. You can use this as an example if you like: https://www.extension.purdue.edu/extmedia/FNR/FNR-269-W.pdf https://www.extension.purdue.edu/extmedia/FNR/FNR-269-W.pdf (which is random, but you need two columns in the PDF). Try select from column 1 near the bottom, across to column 2. PDFs are very diverse. Our algorithm does not always work, alas, but it is significantly better than what existed before. In fact, for some reason, it works well for this document on page 1 and 3 but not so well on page 2! But I no longer have access to the low level tools I used to use to figure out what went wrong.
- amartya916 7y agoThis is so neat. Like someone else mentioned already, this feature has been very useful for me countless times. In fact, when it doesn't work, I tend to blame the PDF itself :). Thanks a ton!
- cfitz 7y agoYup, just open Preview for an image (possibly other documents as well e.g., PDF), go into “markup” mode, and begin to draw with the pen or pencil. Preview will try to “perfect” your drawn check mark, X, straight line, curved line, etc.
- herodotus 7y agoThat's a nice feature! But it was added after we left Apple. I cannot claim any credit for it.
- coldtea 7y agoThat's a different "smart" feature -- the one mentioned has to do with guessing where the selected text continues (when it goes on to a different column, text box, etc). PDFs are more "baked" layouts rather than high level semantic markup, so it's not easy to automatically determine this. The AI is probably a set of heuristics.
