Re: Points vs pixels in a bash script

For the record: I believe I have found a solution: tell application "Finder" to get bounds of window of desktop tells me the resolution of the screen in the same units (of course) as tell application "System Events" to get the title of every window of every process lateron. Thanks again

Re: Points vs pixels in a bash script

Don’t you need to find out what the pixels per inch of the display is first? At 72 dpi or ppi, a pixel = a point. Can you get that info first? > On Jun 8, 2020, at 4:43 PM, Gabriel Zachmann via Cocoa-dev > wrote: > > I know this mailing list might not be the perfect fit for my question,

Except that Apple specifically says they're not. From High Resolution Guidelines for OS X

Re: Points vs pixels in a bash script

Just as an aside, points are not Apple-specifc. They are a typesetting unit equivalent to 1/72 of an inch. It's the same unit used for font sizes. -jeff On Mon, Jun 8, 2020 at 2:43 PM Gabriel Zachmann via Cocoa-dev < cocoa-dev@lists.apple.com> wrote: > I know this mailing list might not be the

Re: Points vs pixels in a bash script

Note that your AppleScript returns the size of ALL monitors combined. With four 1920x1080 monitors in a 2x2 arrangement it shows: 0, 0, 3840, 2160 -Carl > On Jun 8, 2020, at 3:44 PM, Marco S Hyman via Cocoa-dev > wrote: > > Using >> system_profiler SPDisplaysDataType >> I can retrieve

Re: Points vs pixels in a bash script

I don’t have an answer for your question, and I know that this doesn’t actually answer it below, but it may still provide some info to help you move forward. The windowing system is always working in points from a coordinates point of view. So window.frame and view.frame are in points, not

Re: Points vs pixels in a bash script

I don’t have an answer to your question, but to add some clarity Points are scale factor independent unit of measurement. On a retina display there are 2 pixels per point. On a non-retina display there is 1 pixel per point. Say Apple comes out with a display with a scale factor of 17. That

Points vs pixels in a bash script

I know this mailing list might not be the perfect fit for my question, but maybe someone has an idea. I have a problem converting points (I think) to pixels in a bash script. I'd rather not write an extra C/Cocoa utility for that. Using system_profiler SPDisplaysDataType I can retrieve the
