I'm using ImageMagick to resize uploaded images through Terascript. I have a simple BASH script that accepts and argument which is a string that specifies the source file, what to do with it, and the target file. Works ok!
Now I want to create images. This is to implement a 'biological detection' system, or CAPTCHA. So I will create a string, then create an image from the string complete with distortion and noise so that it requires a human to interpret it. To do this I need to use the ImageMagick Convert application and pass to it some arguments like -draw. Easy enough. But then I need to pass the string and some cartesian arguments. This is where the problems come in. The string and arguments need to be quoted, and it appears this is what I am having trouble with. The ImageMagick command to create and image of some text is: convert -size 320x85 canvas:none -font Helvetica -pointsize 72 -draw 'text 25,60 "It works"' -channel RGBA -blur 0x6 -fill darkred -stroke magenta -draw 'text 20,55 "It works"' outputfile.jpg If I enter this into the Terminal it creates an image. However, if I pass this argument to my BASH script using the Command Line action it doesn't work. I expect this is to do with escaping the ' and " but can't seem to find any clues as to what to do. Any help would be appreciated.
