Complex regions

[wurzelmac]

For example: -region 100x100+50+50 is "only" a rectangle.
Is there a possibility to make complex regions such as polygons, or are only rectangles practicable?

Thanks in advance,

use -mask rather than -region and build your own mask shape using -draw

Thanks in advance, wurzelmac

To pixelize:

convert rose: -scale 10% -scale 1000% show:

Thanks a lot,
