Member Function Documentation

◆ DrawPage()

void BOARD_PRINTOUT::DrawPage ( const wxString &  aLayerName = wxEmptyString,
int  aPageNum = 1,
int  aPageCount = 1 
)
virtual

Print a page (or a set of pages).

Note: this function prepare print parameters for the function which actually print the draw layers.

Parameters
aLayerName= a text which can be printed as layer name
aPageNum= the number of the current page (only used to print this value)
aPageCount= the number of pages to ptint (only used to print this value)
