Description
I created a vector grid with A4 paper dimensions - for scale 1:1000 (297*210) in local TM projection (in meters). After that I created print composer set to A4 paper size and created an atlas, and set map properties to be at 1000 scale with fixed scale option checked in "Controlled by atlas" feature. After exporting atlas as images with world files I got this result:
0.084687767409 0.000000000000 0.000000000000 -0.084677419441 671042.972374848556 5050129.284700106829
From world file it now seems that picture has different x and y scale, which is not true. The difference is very very small (0.084677419441 - 0.084687767409 = -0.000010347968). Units are meters so this value should be rounded to significant number of decimal places. For coordinate system in meters - millimeters should be enough. Result should be something like this:
0.085 0.000000000000 0.000000000000 -0.085 671042.972374848556 5050129.284700106829
Some other softwares (ACAD Raster Design for example) recognizes this as image with different scales in x and y direction and cannot do any operation on it because of that.
