I got SVG graphic from friend saved in Illustrator CS6 (16.0.3). Opened it in the same CS6 version on another machine, forced save as, set SVG export format to the same values as origin and files are not the same: in original width="1375px" height="602px" viewBox="0 0 1375 602" after resave width="1375px" height="602px" viewBox="0.0002441 -0.0002441 1375 602" This
This "0.0002441" is ratio of 1/4096. I don't know why it adds it. I know friend is not using any additional settings besides the easy accessible ones. Illustrator
Illustrator according to this 0.0002441 is changing parameters of all objects in drawing. Precision is set to 7 (max).
