Member Function Documentation

wxBitmap * CBGDDKernelBitmapItem::RenderItemToBitmap (  wxSize  szBitmap  )  const [protected, virtual]
 

Function : CBGDDKernelBitmapItem::GetWxBitmap Author : Mikhail Tatarnikov Purpose : Gets the wxBitmap representation of the currently stored KernelBitmap Returns : wxBitmap* - the required version of the KernelBitmap. Exceptions: Parameters: [in] wxSize szBitmap - the size of representation. Notes : Since the KernelBitmap stored in the item can be of considerable size, we have to speed up the drawing (and scaling). It's done by caching the bitmap representations.

Reimplemented from CBGDDCachedItem.
