GR_Image * GR_Win32Image::createImageSegment ( GR_Graphics pG,
const UT_Rect rec 
) [virtual]

The idea is to create a new image from the rectangular segment in device units defined by UT_Rect rec. The Image should be deleted by the calling routine.

Implements GR_Image.

BITMAPINFO* GR_Win32Image::getDIB ( void   )  const [inline]
bool GR_Win32Image::hasAlpha ( void   )  const [virtual]

Returns true if there is any transparency in the image.

Implements GR_RasterImage.


bool GR_Win32Image::isTransparentAt ( UT_sint32  x,
UT_sint32  y 
) [virtual]

Returns true if pixel at point (x,y) in device units is transparent. See gr_UnixImage.cpp for how it's done in GTK.

Implements GR_RasterImage.
