If you are going to rotate/scale etc, it would be best to use the Goo::Canvas. Goo will save it's entire scrolled region to a pdf or svg or png. The Gnome2::Canvas will only allow screenshots of it's visible area, and rotations must be done manually by manipulating the coordinates of the item. But Goo will be slightly slower. So you need to ask yourself what the tradeoffs are. Do you value speed, ability to rotate, or ability to save entire scrollregions to a variety of formats. Goo(Cairo based) is the most advanced ( but still in development), while the Gnome2::Canvas has had it's development status set to frozen, it dosn't save well, but is faster than Goo.

You could also go directly to Cairo and/or a DrawingArea. The only advantage of a canvas type widget, is it's persistence of items. On a DrawingArea, you are writing directly to a pixmap, which has to be reloaded on every expose event, or things disappear. It's tough to drag on a DrawingArea, whereas a canvas makes dragging a breeze.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
