[Qgis-developer] setting size of mapcanvas / map via python in plugin

[Richard Duivenvoorde]

Ok, found it sort of... using python you can resize the Qt-parent
component that QgsMapCanvas inherits from.

Now implemented in HtmlImageMap Plugin: ability to set mapcanvas size,
hence setting output size of image of the map.

Regards,

Richard
