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  bTransparency = false 
) [inherited]

Bitmap resource constructor

Parameters:
hbmp : bitmap resource handle
hpal : (optional) palette, useful for 8bpp DC
bTransparency : (optional) for 32bpp images only, imports trancparency
Returns:
true if everything is ok

int32_t CxImage::Draw ( HDC  hdc,
const RECT &  rect,
RECT *  pClipRect = NULL,
bool  bSmooth = false,
bool  bFlipY = false 
) [inherited]

int32_t CxImage::Draw ( HDC  hdc,
int32_t  x = 0,
int32_t  y = 0,
int32_t  cx = -1,
int32_t  cy = -1,
RECT *  pClipRect = 0,
bool  bSmooth = false,
bool  bFlipY = 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.
bFlipY : draws a mirror image along the y-axis
Returns:
true if everything is ok

int32_t CxImage::Draw2 ( HDC  hdc,
const RECT &  rect 
) [inherited]

int32_t CxImage::Draw2 ( HDC  hdc,
int32_t  x = 0,
int32_t  y = 0,
int32_t  cx = -1,
int32_t  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

HBITMAP CxImage::Draw2HBITMAP ( HDC  hdc,
int32_t  x,

bool  bSmooth 
) [inherited]

renders the image into a HBITMAP handle

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:
HBITMAP handle, NULL in case of error
