| Sep 15, 2013 at 20:15 | comment | added | bill s | @belisarius -- it took me a while, but I've now a added (an updated and expanded version of) this answer to the common pitfalls. | |
| Aug 14, 2013 at 13:21 | comment | added | Dr. belisarius | I think this is a very good topic for this question. Can you formulate an answer there (perhaps including the obvious transformation functions between both coordinate systems)? | |
| Jul 1, 2013 at 5:37 | comment | added | Sjoerd C. de Vries | There's also a difference concerning the position of the center of a pixel. One system starts at the bottom left of a pixel, the other uses the center as reference. | |
| Jun 22, 2013 at 17:41 | comment | added | Simon Woods | I think that's much clearer now. +1 | |
| Jun 22, 2013 at 17:31 | comment | added | bill s | @Simon Woods -- I added more explanation and some references to the help files to try and clarify: row/column are index forms (like a matrix) while position/pixel coordinates are Cartesian forms. | |

I think you mean that images don't use regular Cartesian coordinates. The "first" row of an image is the top row, like matrices. Consider Through@{Image, MatrixPlot, Graphics@Raster@# &, ListDensityPlot}@ IdentityMatrix@5
