/*
|
|
* the class WS_DATA_ITEM (and WS_DATA_ITEM_TEXT) defines
|
|
* a basic shape of a page layout ( frame references and title block )
|
|
* Basic shapes are line, rect and texts
|
|
* the WS_DATA_ITEM coordinates units is the mm, and are relative to
|
|
* one of 4 page corners.
|
|
*
|
|
* These items cannot be drawn or plot "as this". they should be converted
|
|
* to a "draw list" (WS_DRAW_ITEM_BASE and derived items)
|
|
|
|
* The list of these items is stored in a WS_DATA_MODEL instance.
|
|
*
|
|
* When building the draw list:
|
|
* the WS_DATA_MODEL is used to create a WS_DRAW_ITEM_LIST
|
|
* coordinates are converted to draw/plot coordinates.
|
|
* texts are expanded if they contain format symbols.
|
|
* Items with m_RepeatCount > 1 are created m_RepeatCount times
|
|
*
|
|
* the WS_DATA_MODEL is created only once.
|
|
* the WS_DRAW_ITEM_LIST is created each time the page layout is plotted/drawn
|
|
*
|
|
* the WS_DATA_MODEL instance is created from a S expression which
|
|
* describes the page layout (can be the default page layout or a custom file).
