Blueprint, Premium categories, or Rigid (if available) can be enabled

Threshold that defines Mono Lines, Color Lines , Low Density Images and High Density Images can be modified.                             

            Default is 1/10/50 as below :

• Color = - 1 +.“Min. percentage of color pixels”.
• LDI = - 10 + “Min. percentage of non-white pixels”
• HDI = - 50 + “Min. percentage of non-white pixels”

             Meaning:

• Mono is less than 1% color and less than 10% non-White
• Color is more than 1% color and less than 10% non-White
• LDI is no matter the percentage of color more than 10% non-White
• HDI is no matter the percentage of color more than 50% non-White

The value can be modified by increasing or decreasing in 1 using the + and – buttons but also the numeric value can be selected and typed manually as a number, following the rule :

0 <= COLOR <= LDI <= HDI <= 100

Example,  default is changed to 0/20/60 as below.

• Color = - 0 +.“Min. percentage of color pixels”.
• LDI = - 20 + “Min. percentage of non-white pixels”
• HDI = - 60 + “Min. percentage of non-white pixels”

This would mean that:

• Mono is less than 0% color (and less than 20 % non-White) -> this means there will be no Mono Lines
• Color is more than 0% color and less than 20% non-White -> this means anything that has 80% or more of white will be Color
• LDI is no matter the percentage of color more than 20% non-White (but less than 60%)
• HDI is no matter the percentage of color more than 60% non-White
