12.4.6 Text (colour)
You can read coloured dates, numbers and words on coloured backgrounds using this feature check. The
field of view is first converted into a black and white image. It also gives you the option to compare the result
to an expected value. You can also check the print quality of text.
This feature check supports external Teach. Here, the value actually read is adopted as a new expectation
value.
Select the area containing the text.
Always mark only one line. If the text covers multiple lines, you must use several feature checks.
Make sure that the text is marked as precisely as possible.
If the text fluctuates in its location in the image, you can use the "Alignment to text line" feature
check for part location.
