If you left-click on the window, you get a menu that allows the full |

Yes, the problem is, I AM using an existing image. Usually, with IM's |
30 |
display(1), I could add lines and text to images but now, all of a |
31 |

32 |
random color from the background. |

There's lots of USE flags associated with Image Magick, most of which I |
36 |
have no clue about. Perhaps I need some transparency support or something. |
