Functions
Surface8u	convertHBitmap (HBITMAP hbitmap)
Vec2f	toVec2f (const ::POINTFX &p)
	Converts a Win32 POINTFX fixed point point to a cinder::Vec2f.
void	ComDelete (void *p)
	A free function designed to interact with makeComShared.
template<typename T >
shared_ptr< T >	makeComShared (T *p)
	Creates a shared_ptr whose deleter will properly decrement the reference count of a COM object.
void	initializeCom (DWORD params=COINIT_APARTMENTTHREADED|COINIT_DISABLE_OLE1DDE)
	Initializes COM on this thread. Uses Boost's thread local storage to prevent multiple initializations per thread.
Surface8u	convertGdiplusBitmap (Gdiplus::Bitmap &bitmap, bool premultiplied)
Gdiplus::PixelFormat	surfaceChannelOrderToGdiplusPixelFormat (const SurfaceChannelOrder &sco, bool premultiplied)
	Translates a cinder::SurfaceChannelOrder into a Gdiplus::PixelFormat Supports BGR, BGRX, BGRA. Returns PixelFormatUndefined on failure.
Gdiplus::Bitmap *	createGdiplusBitmap (const Surface8u &surface, bool premultiplied)

Function Documentation

Surface8u cinder::msw::convertHBitmap

(

HBITMAP

hbitmap

)

Converts a Win32 HBITMAP to a cinder::Surface8u

Note:

Currently always copies the alpha channel

Vec2f cinder::msw::toVec2f

(

const ::POINTFX &

p

)

Converts a Win32 POINTFX fixed point point to a cinder::Vec2f.

void cinder::msw::ComDelete

(

void *

p

)

A free function designed to interact with makeComShared.

template<typename T >

shared_ptr<T> cinder::msw::makeComShared

(

T *

p

)

Creates a shared_ptr whose deleter will properly decrement the reference count of a COM object.

void cinder::msw::initializeCom

(

DWORD

params = COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE

)

Initializes COM on this thread. Uses Boost's thread local storage to prevent multiple initializations per thread.

Surface8u cinder::msw::convertGdiplusBitmap	(	Gdiplus::Bitmap &	bitmap,
		bool	premultiplied
	)

Copies the contents of a Gdiplus::Bitmap. premultiplied determines whether the result should be premultiplied by alpha

Gdiplus::PixelFormat cinder::msw::surfaceChannelOrderToGdiplusPixelFormat	(	const SurfaceChannelOrder &	sco,
		bool	premultiplied
	)

Translates a cinder::SurfaceChannelOrder into a Gdiplus::PixelFormat Supports BGR, BGRX, BGRA. Returns PixelFormatUndefined on failure.

Gdiplus::Bitmap * cinder::msw::createGdiplusBitmap	(	const Surface8u &	surface,
		bool	premultiplied
	)

Creates a Gdiplus::Bitmap which wraps a cinder::Surface8u. Requires surface to confrom to SurfaceConstraintsGdiPlus and throw SurfaceConstraintsExc if it does not. Caller is responsible for deleting the result.
