![]() ![]() content you dont control, theres API for that. If you only need sampling from your own windows theres API for that, which would speed up your solution and in theory shouldnt cross Catalinas privacy rules.Ħ. Ill agree its pretty a pretty ugly workaround and thats why I dont use it myself.ĥ. The built-in Apple method requires the user learns to click on select color and then the eyedropper but the reat is handled for you and is allowed on Catalina. Using a commandline tool to take the screenshot to which I assume is saving to disk is wasteful and eats into the users write allowance on SSDs, not to mention you have the time involved in writing and reading.ģ. The problems that I can see are as follows.Ģ. Yes and that works to hide the cursor from the screenshot, but I’m taking a screenshot a few times a second in a timer when the screen is being sampled, and this causes the magnifying cursor to flicker and be very difficult to use, so it’s not an option I can use unfortunately.Īt this point I think you should stop for a moment and seriously consider your options. files passed to command line will be ignoredįiles where to save the screen capture, 1 file per Fjellman: u present UI after screencapture is complete.

It needs to always be shown, but be hidden from the screenshot, which is exactly what macOS does with NSCursors. I need a way to treat the cursor as a “layer” on the screen. The problem with that is that it hides my custom magnifying glass cursor. For my own solution, because it’s designed to allow the user to grab a sample from the image they’re editing, I convert the mouse location to a coordinate on the image preview and sample there, completely avoiding any screen shot mechanism. There’s issues with some custom eye dropper controls as some of the techniques for grabbing a values from the screen are blocked on Catalina.It’s cumbersome, yet for handling the color selection, efficient. You can get a eye dropper control for FREE, by using select color and clicking on the eye dropper icon.When the selection is complete or the process is cancelled, I call to show it again. I use a window (which follows the cursor) to show an enlarged area and the current highlighted color.
