Member Function Documentation

void CanvasMask::draw (  Graphics    g )  [inline, virtual]

Draw CanvasObject on 'g', using internal CCS values. Reimplemented from CanvasObject. { if (image != null) { setupDrawMode(g); if (!getTransformOK()) { transformICStoCCS(); } g.drawImage(image, getX1Ccs(), getY1Ccs(), getWidthCcs(), getHeightCcs(), null); } }

Object CanvasMask::clone (    )  [inline, virtual]

Return an identical copy of this CanvasObject. Reimplemented from CanvasObject. { return (new CanvasMask(image, getX1()+0.5, getY1()+0.5, drawColor, transparency, getZoomFactor())); }

boolean CanvasMask::isInside (  double    x, double    y )  [inline]

{ return inBoundingBox(x, y); }

boolean CanvasMask::isNear (  double    x, double    y )  [inline]

{ return isInside(x, y); }

void CanvasMask::setDimension (  double    w, double    h )  [inline]

Resize CanvasObject to width 'w' and height 'h'. Parameters are assumed Image Coordinate System values. Reimplemented from ScribbleObject. { // overrule super.setDimension(w, h), and do nothing return; }

void CanvasMask::doPixelFit (  double    zoomFactor )  [inline]

Round internal ICS values to nearest natural number. Although the ICS values are changed, they are not converted to 'integer' internally. Reimplemented from ScribbleObject. { super.doPixelFit(zoomFactor); setX1((int)getX1() - 0.5); setY1((int)getY1() - 0.5); setStartX(getX1()); setStartY(getY1()); setTransformOK(false); }

void CanvasMask::setColor (  Color    newColor )  [inline]

Reimplemented from ScribbleFigure. { if (newColor == NO_COLOR) { return; } if (getWidth() > 0. && getHeight() > 0.) { drawColor = newColor; int width = (int)(getWidth() + 0.5); int height = (int)(getHeight() + 0.5); ImageBuffer ib = new ImageBuffer(image, width, height); int[] pixels = ib.getPixels(); for (int i=0; i<pixels.length; i++) { if (pixels[i] != NO_PIX) { pixels[i] = drawColor.getRGB(); } } ib.fill(pixels, width, height); image = ib.toImage(); } }

void CanvasMask::setTransparency (  float    trans )  [inline]

Reimplemented from ScribbleFigure. { super.setTransparency(trans); int scaled = (((int)(transparency * 255)) << 24) | 0x00FFFFFF; if (getWidth() > 0. && getHeight() > 0.) { int width = (int)(getWidth() + 0.5); int height = (int)(getHeight() + 0.5); ImageBuffer ib = new ImageBuffer(image, width, height); int[] pixels = ib.getPixels(); for (int i=0; i<pixels.length; i++) { if (pixels[i] != NO_PIX) { pixels[i] = (pixels[i] | 0xFF000000) & scaled; } } ib.fill(pixels, width, height); image = ib.toImage(); } }

Image CanvasMask::getMask (    )  [inline]

{ return image; }

boolean CanvasMask::isInsideCcs (  int    x, int    y )  [inline]

To be removed. Reimplemented from CanvasObject. { return inBoundingBoxCcs(x, y); }

boolean CanvasMask::isNearCcs (  int    x, int    y )  [inline]

To be removed. Reimplemented from CanvasObject. { return isInsideCcs(x, y); }

void CanvasMask::setDimension (  int    w, int    h )  [inline]

Reimplemented from ScribbleObject. { // overrule super.setDimension(w, h), and do nothing return; }

int CanvasMask::changePoint (  int    index, int    x, int    y )  [inline]

Reimplemented from ScribbleFigure. { // overrule super.changePoint(index, x, y), and do nothing return index; }

void CanvasMask::initMask (  int    pixels[], int    w, int    h, Color    color )  [inline, protected]

{ ImageBuffer ib = new ImageBuffer(pixels, w, h); initMask(ib.toImage(), color); }

void CanvasMask::initMask (  Image    im, Color    color )  [inline, protected]

{ resizeable = false; hasLineWidth = false; hasNoColor = false; image = im; if (image != null) { setWidth(image.getWidth(null)); setHeight(image.getHeight(null)); setColor(color); } transformICStoCCS(); }
