Hi everyone,

I am quite new to Power Automate Desktop but have a question regarding the OCR activity.

I would like to understand how to extract text relative to an image as this would be applicable in multipe scenarios.

For simplicity reasons let's say I want to extract the text "OCR Text extraction relative to image" in the green frame and trying to use the "image" in red frame as an anchor point.

So basic idea: Find image > extract from area relative to the image.

Intuitively, I would use " Extract text with OCR" activity and set search mode for "subregion relative to image", then select the red-frame as my image.

Now where do I define the subregion? Are the "X" and "Y" values relative to the found image (meaining I would have to use a negative "y" value to select my green region?

There are several videos and tutorials all using extract data from image file but I couldn't find any explaining this.

So how does the activity actually work?

Thanks in advance and best regards

Nico

Hey Gundam,
I managed to extract the OCR relative to image and from subregion.
It is not very user friendly in my opinion and I don't even know if it is the correct approach approach but it works and as I could not find any other real explanation I made a video on it.
