Comparison
-
Does STREAMdiff compare the image or the actual print stream constructs?
First, the print stream is analyzed, and then the changes are verified to make
sure that the difference is a visual change. STREAMdiff looks for visual
differences between the two print streams, down to the pixel level, and will
capture ALL differences between the two files.
-
What is the difference between an image and a graphic?
These are categories describing AFP and Metacode structures. Graphics are line
drawings, shading, charts, tables and graphs that are created using drawing
commands. Images are the remaining elements, such as logos.
-
During visual comparison, why are the changes split into different AFP objects,
i.e. variable text, overlay text, etc.?
Once a visual change is identified, STREAMdiff next delves into the underlying
AFP structure to determine what type of change has occurred.
-
Why are differences marked on the Control file and not on the Test file where
the changes actually occur?
