Constructor Detail

ImgPreviewPanel

public ImgPreviewPanel()

Creates new form ImgPreviewPanel

Method Detail

loadImage

public void loadImage(java.lang.String fileName)

loads an image from file and puts it into mBufferedImage

paintComponent

public void paintComponent(java.awt.Graphics g)

custom paint method that ensures proper display ratio of images

Overrides:

paintComponent in class javax.swing.JComponent

doImageRescale

public void doImageRescale()

ensures that the image is displayed with the correct ratio as the internal frame is resized

setCrop

public void setCrop()

Sets the video data crop values from the ones calculated from the preview image selection.

doCropCalc

public void doCropCalc()

Calculates crop from current selection rect

setRectfromCropSettings

public void setRectfromCropSettings()

Updates the crop rectangle used in the preview panel based on the current crop values. This is called when detect crop is used and thereafter when the panel is resized.

getPixelPanelScale

public double getPixelPanelScale()

Gets panel coords to actual image pixel coords scale value. Returns the scaling value as a double.

getPixelCoords

public java.awt.Point getPixelCoords(int x,
                                     int y)

Gets the image pixel coords from the corresponding points in the preview panel, by applying the scaling value.

initComponents

private void initComponents()

This method is called from within the constructor to initialize the form. WARNING: Do NOT modify this code. The content of this method is always regenerated by the Form Editor.

formAncestorResized

private void formAncestorResized(java.awt.event.HierarchyEvent evt)
