Paste/Record measurement on the image in photoshop
I have read the forums but did not find the answer I was looking for.
I have images I took with a microscope which show scale. And I have set the desired length measurement with the help of that scale. Now, I can measure where I want on the image and record the measurement, but the results show in a box (something like an excel spreadsheet). However, what I want is to record that measurement ON the image. For example, I want to draw a line on a sample, the sample is 250 µm, I want the@ line to be labeled as a 250 µm line so that the user can read it quick.
Something like what's shown in this image I got from the web. It shows the scale on the bottom left, and it shows the length of the corroded area < This is what I want.
Any help will be greatly appreciated, I've been looking for this since last night.
