Action: Read Screenshot Contents (no input variable?)

[HCC]

Hello,

Normally an OCR recognition module needs a path to know which screenshot
file the module should read from, e.g a path like this :

/storage/emulated/0/Pictures/Screenshots/20240330-155845.png

But the Macrodroid action"Read Screenshot Contents" has no option to specify a fixed
path (or variable) to the input file.

-How does the Macrodroid OCR module know which screenshot file it has to read?

It takes the screenshot then reads from that.

Ok, very helpful, thank you.
Is there a visible sign on the phone screen (or a sound) when MD takes the screenshot?

-I'm asking because the output array variable is always empty when trying the
"Read Screenshot Contents" action (the Macrodroid log file shows no errors and the MD Helper log is empty).

It's designed to not show anything to the user.

To use e.g. the "Take Screenshot" action the smartphone must be rooted.
-Does the device need to be rooted for the "Read Screenshot Contents" action to work?

I don't use a rooted device.

On old devices root access is needed to take screenshots so yeah you need root.

Read screenshot contents works without root.

Make sure you allow time for the action to complete before continuing the macro ie add a wait after it, if you haven't already.

The screenshot action on old devices requires root, it's not the case anymore though.

I'm not sure for this specific action but most of the time the macro will block until the action is done.

I've just checked with no wait after the Read screenshot action and it still works fine.

So I think you are right.

Thank you for pointing this out.

I tried it with different texts on the cell phone screen like browser, file browser,
X-plore, Macrodroid etc. - The Macrodroid log file always shows no errors
and the output array variable "temp" is always empty .
