BITMAPS

aBitmap

)

Allocate a wxBitmap on heap from a memory record, held in a BITMAPS.

Parameters

aBitmap

is from the BITMAPS enum in bitmaps_list.h

Returns

wxBitmap* - caller owns it.

KiScaledBitmap() [1/2]

wxBitmap KiScaledBitmap	(	BITMAPS	aBitmap,
		wxWindow *	aWindow,
		int	aHeight = -1,
		bool	aQuantized = false
	)

Construct a wxBitmap from a memory record, scaling it if device DPI demands it.

Internally this may use caching to avoid scaling the same image twice. If caching is used, it's guaranteed threadsafe.

Parameters

aBitmap	is from the BITMAPS enum in bitmaps_list.h
aWindow	target window for scaling context
aHeight	is the requested image height for the source bitmap, or -1 for any height
aQuantized	if true scaling will be rounded to integers (2X, 3X, etc.).

KiScaledBitmap() [2/2]

wxBitmap KiScaledBitmap	(	const wxBitmap &	aBitmap,
		wxWindow *	aWindow
	)

Overload of the above function that takes another wxBitmap as a parameter.

Parameters

aBitmap	is the source bitmap to scale
aWindow	target window for scaling context
