There's a software who export content as image and provide a metadata files giving the X/Y position and X/Y distance from those points to box elements within the image.
In the code, all thoses values are computed as: "coordinate_in_pixel * dpi"
My question: I really don't get what "coordinate_in_pixel * dpi" should mean, as dpi don't relate to pixel as in the previous formula. After looking and asking many people, it makes no sense for me and for the few who get a bit my misunderstanding (all graphist/prepress/etc) to have the previous formula, what am I missing ? What is expressed by that computing ? As it is from an open source software with others exploiting those values, I'm wondering what is expressed by that formula and that I'm missing.
