Hi,

I know I'm gonna get a lot of stick for this, but I'm really struggling trying to get a rectangle made over an image. So far I have read this page:

http://www.imagemagick.org/script/comma ... .php?#draw

From what I understand about the co-ordinate system, I need:

convert ./wintercard1.jpg -fill white -stroke black -draw "rectangle 0,0 50,600 gravity South" ./wintercard1_new3.jpg

However, that makes a vertical (600px high, 50px wide) rectangle. My rectangle needs to be at the base of the image, and 50 high + 600 wide. Can someone suggest what I'm doing wrong? Maybe I'm mis-understanding how the coordinates system works?

TIA!

Andy

In your code: 0,0 = rectangle top left corner 50,600 = bottom righthand corner so you are getting what you as for; try -draw "rectangle 0,0 600,50 gravity South". I do not know if gravity has any effect in the draw command.

you probably need to put -gravity south outside and before the -draw command

Hi,

Thanks for the replies guys. The box is the right size now, but the damn thing is refusing to draw at the bottom of the image :/
I've also tried "South" (ie uppercase S)... and that doesn't work either

TIA

I still do not know if you can use -gravity with draw as it is referancing the top left corner.

This will work:

I can confirm that

convert logo: -fill red -stroke black -gravity southeast -draw "rectangle 0,0 100,100" show:

does not honor -gravity.

I think -gravity is only sensitive in the following context for -draw

So using -composite as Bonzo said is likely the best way.

gravity only effects text and image placement (and justification! - sic). It is not part of SVG so is not really used for other primitive draw commands.
