MS Office seems to use a somehow quadratic interpolation in the two-stops-color gradient case. Open attached document in PowerPoint. It has in the middle a rectangle with two-stop-color gradient and below it a rectangle with three-stop-color gradient. Above is a screenshot of the two rectangles as rendered in PowerPoint. Then open the file in LibreOffice. LibreOffice has only linear color interpolation, same as MS Office uses, if three or more stops are present. So when you want the color interpolation to be the same in LibreOffice as in MS Office, you have to use at least three color stops in MS Office. I have added a screenshot to the file, because MS Office does not export the two-stop-color interpolation the same way to png as it renders it. -- You are receiving this mail because: You are the assignee for the bug.
