Does Direct2D have CompositingModeCopy like GDI+? -


i trying move virtual white board application gdi+ direct2d. perviously used graphics::setcompositingmode(compositingmodecopy) "eraser" function, can't find similary interface in direct2d.

thanks.

d2d1_compositing_mode_source_copy, requires direct2d 1.1 (windows 8+, or windows 7 sp1 w/ platform update)

also, pairing id2d1rendertarget::pushaxisalignedclip , id2d1rendertarget::clear() can used "erase" rectangular region. works on windows 7 rtm.
