Function Documentation

long CxImage::Blt	(	HDC	pDC,
		long	x = 0,
		long	y = 0
	)			[inherited]

HANDLE CxImage::CopyToHandle

(

)

[inherited]

Transfer the image in a global bitmap handle (clipboard copy)

bool CxImage::CreateFromHANDLE

(

HANDLE

hMem

)

[inherited]

Global object (clipboard paste) constructor

Parameters:

hMem,:

source bitmap object, the clipboard format must be CF_DIB

Returns:

true if everything is ok

bool CxImage::CreateFromHBITMAP	(	HBITMAP	hbmp,
		HPALETTE	hpal = 0
	)			[inherited]

Bitmap resource constructor

Parameters:

	hbmp	: bitmap resource handle
	hpal	: (optional) palette, useful for 8bpp DC

Returns:

true if everything is ok

bool CxImage::CreateFromHICON

(

HICON

hico

)

[inherited]

icon resource constructor

Parameters:

hico

: icon resource handle

Returns:

true if everything is ok

long CxImage::Draw	(	HDC	hdc,
		const RECT &	rect,
		RECT *	pClipRect = NULL,
		bool	bSmooth = false
	)			[inherited]

long CxImage::Draw	(	HDC	hdc,
		long	x = 0,
		long	y = 0,
		long	cx = -1,
		long	cy = -1,
		RECT *	pClipRect = 0,
		bool	bSmooth = false
	)			[inherited]

Draws the image in the specified device context, with support for alpha channel, alpha palette, transparency, opacity.

Parameters:

	hdc	: destination device context
	x,y	: (optional) offset
	cx,cy	: (optional) size. If cx or cy are not specified (or less than 0), the normal width or height will be used If cx or cy are different than width or height, the image will be stretched
	pClipRect	: limit the drawing operations inside a given rectangle in the output device context.
	bSmooth	: activates a bilinear filter that will enhance the appearence for zommed pictures. Quite slow. Needs CXIMAGE_SUPPORT_INTERPOLATION.

Returns:

true if everything is ok

long CxImage::Draw2	(	HDC	hdc,
		const RECT &	rect
	)			[inherited]

long CxImage::Draw2	(	HDC	hdc,
		long	x = 0,
		long	y = 0,
		long	cx = -1,
		long	cy = -1
	)			[inherited]

Draws (stretch) the image with single transparency support

Parameters:

	hdc	: destination device context
	x,y	: (optional) offset
	cx,cy	: (optional) size. If cx or cy are not specified (or less than 0), the normal width or height will be used If cx or cy are different than width or height, the image will be stretched

Returns:

true if everything is ok

long CxImage::DrawString	(	HDC	hdc,
		long	x,
		long	y,
		const TCHAR *	text,
		RGBQUAD	color,
		const TCHAR *	font,
		long	lSize = 0,
		long	lWeight = 400,
		BYTE	bItalic = 0,
		BYTE	bUnderline = 0,
		bool	bSetAlpha = false
	)			[inherited]

long CxImage::DrawStringEx	(	HDC	hdc,
		long	x,
		long	y,
		CXTEXTINFO *	pTextType,
		bool	bSetAlpha = false
	)			[inherited]

void CxImage::InitTextInfo

(

CXTEXTINFO *

txt

)

[inherited]

HBITMAP CxImage::MakeBitmap

(

HDC

hdc = NULL

)

[inherited]

Transfer the image in a bitmap handle

Parameters:

hdc,:

target device context (the screen, usually)

Returns:

bitmap handle, or NULL if an error occurs.

long CxImage::Stretch	(	HDC	hdc,
		const RECT &	rect,
		DWORD	dwRop = SRCCOPY
	)			[inherited]

long CxImage::Stretch	(	HDC	hdc,
		long	xoffset,
		long	yoffset,
		long	xsize,
		long	ysize,
		DWORD	dwRop = SRCCOPY
	)			[inherited]

Stretch the image. Obsolete: use Draw() or Draw2()

Parameters:

	hdc	: destination device context
	xoffset,yoffset	: (optional) offset
	xsize,ysize	: size.
	dwRop	: raster operation code (see BitBlt documentation)

Returns:

true if everything is ok

long CxImage::Tile	(	HDC	hdc,
		RECT *	rc
	)			[inherited]

Tiles the device context in the specified rectangle with the image.

Parameters:

	hdc	: destination device context
	rc	: tiled rectangle in the output device context

Returns:

true if everything is ok
