scaling a tile pattern?

[junge]

Hi

I would like to know how it is possible to scale (or generally manipulate the geometry of) the built-in patterns? For example if I generate a picture with a patternfilled rectangle:

convert -size 500x500 xc:white -tile pattern:bricks -draw 'rectangle 100,100 400,400' mybricks.png

and I would like the pattern to be resized so the bricks are twice as big as the default size. How do I do that?

I have tried the -scale option, but it seems to scale the whole picture no matter how I use it, even if I use parenthesis.

Regards Junge

compare

convert -size 500x500 pattern:bricks mybricks.png

with

convert -size 250x250 pattern:bricks -scale 200% mybrick2.png


you need to reduce down the -size in proportion to the desired scaling
