Class   : RenderLargeImageCommand
Command : renderLargeImage

This command allows the user to enable the rendering of images
larger than the screen.

Synopsis:
None <- renderLargeImage(width=None, height=None, border=0,
                          outputFile='test.jpg', backbuffer=True)
width, height   : to specify either the width or the height.
border          : (default 0) specify the size of a border can be any

buildFormDescr(self, formName)

source code

descr <- buildFormDescr(self, formName): this virtual method is implemented in the classes derived from Command. This is where the inputFormDescr is created and the description of the widgets appended. If a command has several inputForm buildFormDescr should build all the inputFormDescr and you do a if / elif check to know which one to create. formName : string name of the form corresponding to this descr.
