Hi. I'm using Magick++ to code an example of the Affine Transformation but
once I build the DrawableAffine object with this matrix: {1, 0, 0, 1, 50,
100} and I use image.write(filename) I got exactly the same image that I
used as input.

I noticed this problem working under MS - Windows using the command convert
-affine 1,0,0,1,50,100 -transform input.jpg output.jpg (by the way, I don't
know what is the role of the -transform option in this command neither if
it's necessary to achive the desired effect in Magick++). By the other hand,
some guys from Java Advanced Imaging (which I was testing too) told me there
was no way of coding the Image's coordinate system origin into a file; I
wonder if your convert -affine command under linux (which is really the only
one that achives the effect) is using some other tricks to do its work.

I'd appreciate somebody could explain me this.

Thanks.
