MATLAB App for measurement of images
Step 1: Click load. This will allow you to select an image (jpeg,png,tif,etc).
Step 2: Click V-Scale. Draw a line the length of 1 vertical unit in the image.
Step 3: Click H-Scale. Draw a line the length of 1 horizontal unit in the image.
Step 4: Click Set Origin. Place a point where you want the origin to be set.
Step 5: Click Line. This will allow you to draw a line and will output the length and angle.
To add more lines: click line and draw another line.
To see line endpoint coordinates: Click on the line of interest, it will display coordinates below the image (origin must be set!)
To move lines with arrow keys: Click on the line of interest, use arrow keys to navigate.
To set precise length and angle: Click on the line of interest, change value of angle/length. Click enter.
