I get that. Thank you.

Stupid me. Thank you so much

Thanks. When I try your code, it runs well. However when I try to make an output as a variable: infile="overlay.png" outfile="overlay_cleaned.png" width=3 w2=`convert $infile -format "%[fx:w-2]" info:` h2=`convert $infile -format "%[fx:h-2]" info:` convert $infile -background white -flatten -fill ...

Doesn't Imagemagick support that?

This one is cleaner. Thank you so much

Can I adjust the width of the line in pixel?

Let's say that I have a vector image. What should I do?

I have tried to do that myself, and haven't succeeded. I ask you in a seperate thread viewtopic.php?f=1&t=26191&p=114987#p114987 and you say there is no way. So can you help me again? Thank you.

Sorry for my bad English. I have checked the dictionary again and edit the post to make it clearer. Hopefully this time you won't be confused.

The blue line isn't in my image, maybe it's from the forum or the image host. I don't know.

So I can't do that, is that right?

I have an image like this: http://www.upsieutoc.com/images/2014/09/02/overlay.md.png I want to convert it to dash line only. I have tried convert input.png -draw "stroke-dasharray 10 3 3 3" output.png or convert input.png -draw "stroke-dasharray 10 3 3 3 path 'M 10,40 L 90,40'" output.png as in http ...

Although it's still an indirect solution, your command is more intuitive. Thank you.

Say I have a picture with caption "A", I want to change it to "A and B" without knowing A? The only way I know so far is then edit the old caption. Is there any better solution?

Sorry for making you confused. I'll try to explain better. These are three images of the output when the argument of octagon is 1, 3 and 5: http://upanh.biz/images/2014/07/30/1.png http://upanh.biz/images/2014/07/30/3.png http://upanh.biz/images/2014/07/30/5.png The point is, when you enlarge the ...

If I want to customize the width of the output border in pixel, what should I do? I can change the argument in the octagon kernel, but I would like to control exactly how wide it is. Because this is the border, I would like when it is enlarges, it is aligned it in the middle, not in left or right ...

so what operation should I use?

How can I do this with another color besides red? Say black. At first, I think I can change all the red to black, but the output is all black. However, when I change to other colors like orange, the output is good. I have tried changing some other color in other positions in your code but haven't ...
