      • ignoreNonImageWidths

        public void ignoreNonImageWidths​(boolean ignoreNonImageWidths)
        Determines whether to ignore the width of non-image components when calculating the preferred width (default false, i.e. the maximum of the widths of all components is used). When true, components that do not fit the window will be truncated at the right. The width of the 0th component (the ImageCanvas) is always taken into account.

        public void layoutContainer​(java.awt.Container target)
        Lays out the container and calls ImageCanvas.resizeCanvas() to adjust the image canvas size as needed.
