How to Auto-Hotpoint a Diagram

In DocuStudio, hotpoints can be automatically applied to a diagram using Optical Character Recognition ("OCR") algorithms that detect and apply hotpoints.

Note: auto-hotpointing is not 100% accurate when hotpointing 
raster images (.jpg, .png, .gif, etc). 

The OCR algorithms rely on the quality of the callout numbers in the image to map callouts numbers to item numbers in the bill of materials. For example, the algorithm(s) may apply numbers like '7' or '1' to lines in the diagram that look like they could be item numbers. 

Note: unless using an .svg image, there is always some manual
review and repair required for hotpoints.
