I'm implementing a spec in which an image is displayed in a Gtk2::Textview. Simple enough to do, but the spec requires optional extras, such as displaying padding around the image and detecting clicks on it.
Taking one problem at a time:
1. Sometimes the image must be displayed its origina
Try creating a new (empty) image of the required size and then use cairo to
fill it with the desired contents. The following link may help you (though
it is in C and not perl, but the API is the same):

Hi Les,
See if this works better for the cat.

Hi Les,
If you put the pixbuf in an image widget and the image widget in an event box
then you can get your mouse clicks from the pixbuf. The event box can then be
added to the textview widget.

How, exactly?
We have Gtk2::TextBuffer->insert for inserting text, Gtk2::TextBuffer->insert_pixbuf for inserting pixbufs, but no equivalent method for inserting an event box (something like Gtk2::TextBuffer->insert_event_box ).
Pe
Try inserting a widget into the textview and capture the clicks on the widget.
In this case, an event box with an image widget and pixbuf.

Two down, one to go!
3. The spec wants the image to be displayable on the left or right of the textview, with any accompanying text at the top, middle or bottom of the image.
I used Gtk2::TextTags with the 'justification' and 'rise' properties set. 'justification' works just fine when there
It sounds like some tricky layout features for the textview. Maybe wrapping
text around images?
Not sure how to go about doing this. One thing to try is putting another
textview in there with the image. Then you can size it to the image height and
could resize it based on the overall window
