IUP_SDK_API IdrawCanvas* iupdrvDrawCreateCanvas ( Ihandle * ih )

Creates a draw canvas based on an IupCanvas. This will create an image for offscreen drawing.

IUP_SDK_API void iupdrvDrawKillCanvas ( IdrawCanvas * dc )

Destroys the IdrawCanvas.

IUP_SDK_API void iupdrvDrawFlush ( IdrawCanvas * dc )

Draws the ofscreen image on the screen.

IUP_SDK_API void iupdrvDrawUpdateSize ( IdrawCanvas * dc )

Rebuild the offscreen image if the canvas size has changed. Automatically done in iupdrvDrawCreateCanvas.

		long	color,
		const char *	font,
		int	flags,
		double	text_orientation
	)

Draws a text. x,y is at left,top corner of the text.

IUP_SDK_API void iupdrvDrawImage	(	IdrawCanvas *	dc,
		const char *	name,
		int	make_inactive,
		const char *	bgcolor,
		int	x,
		int	y,
		int	w,
		int	h
	)

Draws an image. x,y is at left,top corner of the image.

IUP_SDK_API void iupdrvDrawSetClipRect	(	IdrawCanvas *	dc,
		int	x1,

		int *	x1,
		int *	y1,
		int *	x2,
		int *	y2
	)

Returns the last rectangle set in iupdrvDrawSetClipRect.

IUP_SDK_API void iupdrvDrawSelectRect	(	IdrawCanvas *	dc,
