Constructor Detail

ImageComponentImage

public ImageComponentImage(ImageComponent iv,
                           ImageComponentUI controls)

Constructor.

Parameters:

iv -

controls -

imageCanvas -

Method Detail

initializeCanvas

public void initializeCanvas()

Does initial setup for the canvas. The imageCanvas in ImageViewControls must be created first.

dispose

public void dispose()

Called when the View is to be disposed

calculateMainRectangles

public void calculateMainRectangles()

Calculates the origRect, orientedOrigRect, and orientedRect from the imageRect and the imageModel.

showSelection

public void showSelection(boolean force)

Draws the current selection on the screen and calls showSelectedArea, showSelectedLine, or showProfile, as appropriate. Thus when it is called, other views will be updated.

showZoom

public void showZoom(org.eclipse.swt.events.MouseEvent ev,
                     boolean in)

Zooms in or out centered on the mouse coordinates.

Parameters:

ev -

in - True to zoom in, false to zoom out.

resetZoom

public void resetZoom()

Resets the zoom to full size. This affects the zoom area whether done in the main view or the zoom view.

showPeaks

public void showPeaks()

Draws red squares around all peaks using the currentLinePeakWidth.

showSelectedPeaks

public void showSelectedPeaks(float[] peaksToColor)

First calls showPeaks to draw red squares, then draws green squares around all peaks in the array using the currentLinePeakWidth.

Parameters:

peaksToColor - An array of TotalCryst coordinates [y0,z0,y1,z1,...] to have a green square. Used in PeakSearchSptView to show the selected peaks in green.

changeImageRect

public void changeImageRect(org.eclipse.swt.graphics.Rectangle rect,
                            float[] areaAsFloat,
                            java.lang.String fileName,
                            ImageModel _imageModel)

Sets a new image rectangle to display along with the new data and name of the file.

Parameters:

rect - The new Rectangle.

areaAsFloat - The new data.

fileName - The new name of the file.

_imageModel - The new ImageModel. If null, then make a new ImageModel.

displayImage

public void displayImage()

Update the image display.
