Function Documentation

bool CxImage::SelectionAddColor (  RGBQUAD  c  )  [inherited]

Adds to the selection all the pixels matching the specified color.

bool CxImage::SelectionAddEllipse (  RECT  r  )  [inherited]

Adds an ellipse to the existing selection.

bool CxImage::SelectionAddPixel (  int  x, int  y )  [inherited]

Adds a single pixel to the existing selection.

bool CxImage::SelectionAddPolygon (  POINT *  points, long  npoints )  [inherited]

Adds a polygonal region to the existing selection. points points to an array of POINT structures. Each structure specifies the x-coordinate and y-coordinate of one vertex of the polygon. npoints specifies the number of POINT structures in the array pointed to by points.

bool CxImage::SelectionAddRect (  RECT  r  )  [inherited]

Adds a rectangle to the existing selection.

bool CxImage::SelectionClear (   )  [inherited]

Empties the selection.

bool CxImage::SelectionCopy (  CxImage &  from  )  [inherited]

Imports an existing region from another image with the same width and height.

bool CxImage::SelectionCreate (   )  [inherited]

Allocates an empty selection.

bool CxImage::SelectionDelete (   )  [inherited]

Deallocates the selction.

void CxImage::SelectionGetBox (  RECT &  r  )  [inherited]

Gets the smallest rectangle that contains the selection

bool CxImage::SelectionInvert (   )  [inherited]

Inverts the selection.

bool CxImage::SelectionIsInside (  long  x, long  y )  [inherited]

Checks if the coordinates are inside the selection.

bool CxImage::SelectionIsValid (   )  [inherited]

Checks if the image has a valid selection.

bool CxImage::SelectionSplit (  CxImage *  dest  )  [inherited]

Exports the selection channel in a 8bpp grayscale image.

bool CxImage::SelectionToHRGN (  HRGN &  region  )  [inherited]

Converts the selection in a HRGN object.
